A new Air Conditioner on your old duct system?

When you purchase a new air conditioner from Precision Comfort Systems in Indiana, you get some hard-to-find custom services. Think about this. While you’re investing a few thousand dollars for a new air conditioner, your investment could also include an upgraded duct system! See our new video that shows how custom duct fittings are made in our shop. See how we can custom design important duct parts for your home. This service can make a big difference for your new air conditioner.

A new furnace is just as important as a new air conditioner. Both systems rely on your duct system to transport the proper volume of comfort to each room. Many homes have a wonderful new air conditioner or new furnace. But the old duct system remains inadequate for proper comfort distribution. Precision Comfort Systems is in the custom sheet metal, duct fabrication business. Most of our competition use store-bought ducts and duct fittings. But we create some very custom fittings to increase your comfort and energy efficiency. We gain our experience through the hundreds of custom new homes for which we design and install the best in comfort systems. Most contractors only work in existing homes, replacing air conditioners and furnaces. Most have never built a new duct system on any job!

We are different. Watch the video.

When Precision Comfort SA new air conditioner should get new duct fittingsystems examines your old furnace and air conditioner, we take pride in going the extra step to evaluate the duct “fittings”. These are the pieces that connect the furnace or fan cabinet to the duct system. This is where the highest air volume and air velocity is found and it’s also where a new custom duct fitting can make the most improvement. Many times, when the duct system is accessible, we are even able to make changes downstream in the duct system to help a particularly uncomfortable area in your home. Remember, even the best new air conditioner or furnace is DOA if it is unable to deliver the comfort to the rooms where your family spends their time.


Vectren Natural Gas: Special offer for new gas meters

Your neighbors heat their homes with natural gas heat but your home does not even have a natural gas meter? What’s up withIs natural gas heat better than electric heat? that?

If your neighborhood already has homes with a natural gas meter, you are very lucky. You have the great opportunity to choose between your current electric heat pump or a natural gas furnace.

Precision Comfort Systems is working with Vectren (sometimes better known as Indiana Gas) to finally get a natural gas meter to your home. Heating with natural gas instead of an electric heat pump has many advantages:

  • Natural gas heat delivers a warmer register air temperature.
  • Natural gas heat costs much less to heat your home compared to your old heat pump.
  • If homes in your neighborhood have a natural gas meter but your home does not, chances are it will be valued a bit lower. If you sell your home, it may not sell as quickly as comparable homes with a natural gas meter.

Precision Comfort Systems has been selected to participate in a very appealing rebate offer to cut the cost of installing a natural gas meter for your home. In fact, getting a new gas line to your furnace location could be $zero! This covers one of our biggest obstacles in upgrading homes like yours to natural gas heat. Let us show you how to get instant rebates starting at $1100 toward your natural gas upgrade. And there are several other rebates to get even more than $1100!

How do I know if my home qualifies for these instant rebates?

This is a very easy test. If your home has never had a natural gas meter from Vectren, but there is a Vectren gas line on or near your property, you should qualify. Check with your neighbors closest to your home to see if their natural gas meter is from Vectren.

Call Precision Comfort Systems for a no obligation site visit to determine if your home qualifies for this limited time offer. We will also discuss how much it would cost to convert your heating system to natural gas and how much you could save in your heating costs. Call Ryan at 317-867-2665.

This is the perfect opportunity to catch up to the neighbors. Call us and we will make this an easy upgrade for your home and a great investment for your family.

When to use Emergency Heat on a heat pump

Emergency Heat setting can double billsEmergency Heat sounds like a wonderful feature for a heating system. It sounds comforting to push the “Power Boost” button during the blizzard. Especially in times of a winter emergency as defined by our central Indiana weather personalities on TV. I am waiting for the day I hear, “… that’s right Bob, we are bracing for our first 2 to 3.6 inches of snow tonight and we will be tracking it throughout your evening TV shows and by the way, you should be rushing to your thermostat and switching into Emergency Heat as soon as possible!

What is Emergency Heat and when should you use it? An Emergency Heat switch is found on most electric heat pump thermostats. Sometimes it is abbreviated as “Em.Ht.” and sometimes it is called Auxiliary Heat (Aux.Ht.). Gas furnaces do not have this feature. The Emergency Heat switch is very easy to understand; it simply turns off your heat pump. But you do not want to do this unless you enjoy electric bills that are twice what they should be.

Your heat pump is a very efficient means of heating your home. Read my previous blogs about heat pump efficiency. All heat pump systems in Indiana also have backup heating coils to assist the heat pump in very cold weather. The backup coils are similar to a much less efficient, portable space heater or the type of heat coils you would see in an old toaster. Electric heating coils are only about one-third as efficient as the heat pump. But fortunately they only account for about 15% to 20 % of your home’s total winter heating needs in Central Indiana. The more efficient heat pump is responsible for most (80% to 85%) of your winter heating. Unless of course you make the mistake and turn off the heat pump!

Do not turn off your heat pump! Some nasty advice is given, even from heating contractors who do not know any better, that you can use the emergency heat setting on your thermostat and “give the heat pump a break when the weather gets cold”. Well take it from me. This switch named “em. ht.” is misnamed. It has nothing to do with getting extra heating capacity or serving as a cold day setting. It should be named, “DOUBLE OR TRIPLE MY BILLS!” When you switch to “em. ht.”, you turn off your heat pump and now the more expensive backup furnace (toaster coils) are heating your home at two to three times the cost.

Don’t do this! Allow the heat pump to run and love it. New heat pumps are very efficient and they are designed to run non stop when you need it most so your heating bill is normal. Even older heat pumps are much better than the electric furnace. Heat pumps are so efficient that even if you need to raise the thermostat a degree or two on the worst winter days, you will still be better off in the normal heating mode and not switching to emergency heat.

If your heat pump is too old, then its ability to move heat may be less than what it should be. Call Precision Comfort Systems, your Central Indiana heat pump specialists, to evaluate your current heat pump. We can tune it up or eventually replace it so you are getting the most from the current heat pump technology.

When are you supposed to use this switch? If you find that your heat pump is not working (read how to test this on your own) then you can switch to emergency heat until a technician from Precision Comfort Systems can visit your home. Or perhaps a part needs to be ordered. Our technician may leave your system in the emergency heat mode for a short time until the heat pump can be repaired.

What if it is very, very cold? Cold weather is still no reason to turn off your heat pump. A heat pump is slightly less efficient in cold weather than it is in normal 20 to 30 degree winter weather, but it is never less efficient than the backup heat. So switching to Emergency Heat will always increase your bills. And most heat pumps will, in the normal heating mode, automatically use all the electric backup heat if necessary to heat your home. You do not get extra heat when switching to emergency heat. (If your heating contractor has custom wired your system to “save” some backup heat capacity solely for the Emergency Heat setting, there is no reason to do this and it should be changed back.)

Most important, be sure you have someone servicing your heat pump, that understands heat pumps. Call Precision Comfort Systems, your Central Indiana heat pump specialists, to service your heat pump.

Home Humidity Solutions for Health & Comfort

Trust your nose. Especially in the humid summer months, is your home humidity where it should be for the best health and comfort? How do you control home humidity? What is the right humidity level and how do I read humidity? The easiest answer is to trust your nose. Do you smell mildew or dampness in the basement? If you do, you are probably growing some things in hidden places that are creating these odors. Improve your health and comfort with proper humidity control.

So far, this summer has been the perfect example of why you may need to pay more attention to the humidity level in your home. The weather this season has been extremely humid, but only moderately hot. This is not a good combination for most homes and especially if you have a basement you should consider additional dehumidification to improve your health and comfort. Normally, when it gets hot and humid in the summer, your air conditioner will run frequently enough to take moisture out of the air. Your goal is to condition your home to about 75 degrees and about 50% relative humidity. But if the weather is mild and your air conditioner does not run enough, you may have humidity readings closer to 60%. If you are at 60% RH or higher in a basement you are not going to be happy.

In my home, I have run two portable dehumidifiers in the past to help keep the humidity levels in the comfort zone. Unfortunately, these units are not made well and only last 2 to 3 years. They are also not very efficient. Recently, I changed to a “whole house dehumidifier” system and for the first time my family is now experiencing true summer comfort. The basement is a healthy 51% RH and the upstairs is an amazing 42% RH to 47% RH. Dry air is very comfortable! And I can only imagine that any mildew in the basement has now been starved of it’s necessary diet of moist air. The whole house dehumidifier we chose was a high efficiency model which means it uses less electricity for each gallon of water it removes. Also, we have now raised the temperature setting at our thermostat which will save more money.

DBest Home Humidity for health and comfortid I mention the water removal? Wow! It has a clear hose that drains the water and I watched this the first day. I could not believe how much water it was sucking from the air in my home as well as the moisture stored in all the walls, furniture, clothes, wood floors and everything else. After a couple days, it settled down and it now runs only occasionally to keep the house at the perfect humidity level for our comfort and I presume, health.

I suggest that you purchase a temperature/humidity monitor at the home center. If you discover (or even if you simply suspect) that your home humidity is too high, call Precision Comfort Systems to see if a whole house dehumidification system will work in your home. It sure helped mine!

Indiana hot weather air conditioner service

Hot, humid summer weather… you know it’s coming! The only good thing about  the Indianapolis area getting hot and humid is… we all have something to talk about.  And what’s more, almost all of us will finally agree on something; It’s HOT and we love our air conditioning! At Precision Comfort Systems, our Indianapolis air conditioner, AC service calls have been increasing. The AC service department has been busy responding to all the No Cooling calls in Westfield, Noblesville, Fishers, Carmel and the other communities surprised by our early heat this year. Much of the time the service technician spends on an AC service call is answering questions like, “Is it OK if my AC is running non stop?” “How can I lower my high air conditioning bills?” Where should I set my AC thermostat temperature?”

Precision Comfort Systems AC service technicians are the best and they know the answers to most air conditioning questions. But I thought I would help them out by answering some of the most common air conditioning and summer comfort questions. Here are the questions we hear the most during the hot summer weather:

Why does my air conditioner never turn off on the hot days? It’s OK. In Central Indiana, air conditioners are sized for normal summer conditions of 15 to 20 degrees warmer outside than inside. So if it gets 20 degrees warmer outside than your thermostat setting, you will most likely see your AC running all the time. But even in extreme weather if you can cool your home 20 degrees less than say 100 degrees, your will still maintain a reasonably comfortable temperature for mid and late afternoon. And then by evening it should start to catch up. If you cannot maintain at least 15 degrees cooler than the outdoor temperature, Call Us!

Is my air conditioner size too small? It could be, but do not judge your AC size on the hottest day of the year. In Indiana, 95 degrees outside temperature is very rare. Normal is more like 88 to 90 for a hot day. If your AC will not maintain 75 degrees inside when it’s 88 degrees outside it may be too small or it may not be working properly. A Precision Comfort Technician can determine this and tell you the truth.

Do I need a new high-efficiency air conditioner or just an AC repair? We try our best to get the full life out of your current air conditioner. AC life expectancy is about 13 to 17 years (average 15 years). Some repairs can make a big difference and it is very much worth the cost of AC service. But eventually you need an honest technician to tell you when it’s time to upgrade to a new, higher efficiency, more dependable air conditioner.

What are some easy ways to save on air conditioning costs? Here are two very easy and free AC tips. On bright hot summer days, close the drapes or blinds on the sunny side of the home. Solar heat can account for 50% of your AC costs and air conditioning load. Also, if you are air conditioning today and you plan on air conditioning tomorrow, do not open your home tonight. The night air is cool, but it is still humid. Summer humidity in Indiana can cause you AC bills to double.

Where should I set my air conditioning thermostat temperature? This is a tough one. Summer comfort is very subjective for each of us. (I think we are more sensitive to temperature in the summer than we are in the winter.) The first thing to note is that your home thermostat(s) may not be perfectly accurate, so do not get too set on an exact number. Cool to your personal comfort level but keep these things in mind; 1) you normally only have the ability to cool 20 degrees from the outside temperature, 2) each degree you lower the thermostat you could add 10% to 15% to your air conditioning bill, 3) if you wait until late afternoon to “cool down” the home, the AC may not be capable of reducing the home temperature during peak conditions.

Hope this helps. Keep Cool! If your AC fails, call Precision Comfort Systems! We offer much more than AC service repair. When you’re having comfort problems, we offer an honest evaluation of your heating and cooling system as well as your entire home. Our trained technicians have the experience to find your problem, and it’s not always a new system. And don’t forget, we offer free second opinions!

How to Cool Hot Upstairs rooms with a new AC

The hot summer days and especially the nights bring back one of the most common home comfort problems: a hot upstairs. Despite your air conditioner repair man saying the AC is tuned up and running properly, the bedrooms on the second floor are so hot, many in the family choose to sleep downstairs. Better yet, if you have one, you may find relief 10 to 15 degrees cooler in the basement! How can a home’s air conditioning system become so imbalanced? How can you fix a hot upstairs during a hot Indianapolis summer? How can you improve the air conditioning in the second floor rooms?

First let’s mention the things that will not help your hot rooms in the summer:

  •  A new air conditioning system will not likely help.
  • An air conditioning system tune up will not help.
  • Closing all the downstairs registers may help the hot upstairs a little, but your air conditioning system may suffer from inadequate airflow.
  • Attic fans are overrated and can cause more problems sucking air conditioned air out of your home.
  • More attic insulation helps, but only if you have very little now. Adding more to an adequate amount will do very little.
  • Ceiling fans are a mild consolation. They circulate the warm air but do not cool it and even add a little heat to the room.

So what is the solution to a hot upstairs where the second floor rooms need more air conditioning? You need a heating contractor that understands air duct design. Most HVAC dealers replace heating and air conditioning systems, but do not design and install new, premium air distribution systems in new homes. Precision Comfort Systems is the top choice for Indianapolis area builders when it comes to a balanced home air conditioning system. Let Precision look at your air conditioning system to see what changes are needed in your duct system to finally improve your hot upstairs.

When is the right time to do this? The ideal time is when you purchase a new air conditioner and or furnace. Thus the reason for the title of this blog… How to Cool Hot Upstairs rooms with a new AC. Do not make the mistake of simply buying a new air conditioner without having a duct design specialist examine your duct system. The first 10 feet of your duct system can be the most important factors and a Precision Comfort specialist will always consider your total home comfort when quoting a new air conditioning system. We even offer a complete home inspection that can identify other major sources of your summer discomfort.

Are you ready to get serious about your hot upstairs? Call Precision and let’s look for a new duct route to the hot second floor rooms. Let’s see if a second, high efficiency air conditioner can be used for the upstairs. Let’s see if we can add a zoning system to the entire home. You need a Precision air distribution design specialist when you buy a new air conditioner!

Hot Upstairs in the Hot Summer Weather?

Do you have a hot upstairs during the summer air conditioning season? I’m sure it is of little consolation for me to tell you that you are not alone and that this is one of the most common air conditioning problems we hear about. What should you do if your upstairs is much hotter than the downstairs? Do you need a more efficient air conditioner or a larger air conditioner? Before I suggest solutions, let’s discuss why the upstairs is so uncomfortable during hot summer weather.

Cooling the upstairs of a two-story home is a challenge for many reasons. The downstairs is usually closer to the air conditioner fan and it gets most of the airflow. The thermostat is usually downstairs, it senses the plentiful cool air in the downstairs, and shuts off the air conditioner before the upstairs is cool. The upstairs has a hot attic above it. The ducts to the upstairs are commonly undersized considering the extra distance from the fan.

Another very significant factor is when a home has any two-story room (foyer, great room, etc.) that allows much of the downstairs heat to flow into and gather in the upstairs. Worse yet, homes with an upstairs open loft or balcony may have sitting areas in this heat collection zone. The cool conditioned air delivered to these open rooms will often fall to the downstairs via the quickest route possible and add to the premature cooling of the downstairs thermostat.

Here is the bad news first. A new high efficiency air conditioner or a larger air conditioner will not help this imbalance. Do not accept a sales proposal based on this claim. The most common reason for the hot upstairs is the lack of air flow to the hot rooms. They are normally farther from the furnace than the downstairs rooms and need larger ducts. If your ducts are accessible, we may be able to make some changes to help cool your upstairs better. Good duct design during home construction is what Precision Comfort Systems is known for. We can apply our new home design experience to your home if your ducts are accessible.

Here are some tips if we cannot change the duct system:

  • Close all the blinds upstairs during the day.
  • Close basement registers. Close the downstairs registers closest to the thermostat but do not close all the downstairs registers.
  • Try running the AC fan in the “continuous” mode. If it helps great, but if it is only a slight benefit, remember that the fan is costing a bit more to run all the time.
  • In the rooms that are two stories high and open to the upstairs, try a ceiling fan to counter the upward heat flow. In other rooms, use ceiling fans only when you are in the room and only if they help. They cost money to run.
  • Check your attic insulation. Many attics need more insulation added after many years of storage, maintenance traffic and sometimes even weather damage to the old insulation.
  • Call Precision Comfort Systems to see if your home is an easy candidate for a zone system or maybe even a new, second air conditioner dedicated for the upstairs. This is the ultimate fix if your home layout allows it.


Geothermal in below zero temps

Just a quick  blog entry, before our very cold below zero weather sets in this weekend. Yes, your geothermal heating system is the best in the world. That is… it is the most efficient system you could have chosen for your home. But some geothermal owners confuse efficiency with capacity. Even though geothermal is very efficient, we still size these heating and cooling systems just like all the other systems.

What does this mean? When does my geothermal heat pump, my standard heat pump or my gas furnace no longer keep my home at the 72 degrees that I normally request?

The industry standard for Central Indiana (guidelines from the Air Conditioning Contractors of America) is to maintain 70 degrees when it is 2 degrees outside. We say, 2 degrees is the “design temperature.” So this means a properly sized heating system would be able to maintain a 68 degree temperature difference. But we normally plan for and size for colder weather. With a Precision Comfort heating system, you should be able to maintain 70 degrees even in temperatures below zero.

How far below zero?

Every home is different and other variables like wind and solar heat will influence this. As you know (look at the date of this blog entry) our forecast is for -15 degrees below zero with a 24 mph wind. If your home is exposed to the wind, you may not be able to maintain 70 degrees in your home at these conditions. As long as you are staying in the sixties during these extreme conditions, your system is likely working perfect, as designed.

Should you have purchased a larger system with more heat capacity? No. We size for 99.9% of all winter hours in Central Indiana. If we sized systems for the extreme (as the weatherman said today… “Barbaric Cold”) then it would be much too large in all the other normal hours.

Be patient and the weather will warm to normal.

Miracle Amish heater savings?… Not!

Amish electric heater! Miracle heat! Amazing new technology! Free electric heater! Energy Saving fireplace heater! You’ve seen these full page ads in the newspaper and since they continue to show up, I can only guess that they are so successful that thousands of buyers are being ripped off every day. In fact, the soon to be disappointed are probably in a hurry to take part in this scam since it is a limited time only, free offer and their zip code is miraculously and thankfully included in the next region recently opened for new orders. Well in terms of electric heating efficiency, you guessed it… this is a not a new and amazing miracle heater.

Here is the 2013 update of my perennial, portable electric heater review. Since Precision Comfort Systems in Westfield is known as the heating and cooling specialists in the Indianapolis area, we get many questions about the energy savings claimed by full page ads featuring plug in portable electric heaters. Despite giving you enough text for a long breakfast read, most of these claims are very misleading. In fact, for many families, these plug in portable heaters can actually double their energy bill.

Here’s the truth. When you create heat with electricity, you have only a few options. Most whole house electric heating systems in the Indianapolis area are heat pumps. Heat pumps and especially geothermal heat pumps are fantastic! The only other electric heat option is to put electricity into some type of “resistant conductor” and this causes the conductor to glow warm and thus gives off some type of heat. You are already familiar with this type of electric heat. It’s in your toaster, your hair dryer, electric stove top and oven, electric clothes dryer, incandescent light bulb, heat lamp… you get the idea. I like to refer to it as simply toaster heat.

Here’s the science. All electric resistance toaster heat is exactly the same (poor) efficiency. You will always get (a relatively small amount) 3413 units of heat (BTUs) for each unit of electricity (kWh) you put in. No variations. No miracles. No new efficiencies from the Amish. Compare this to a heat pump at 2 to 3 times the efficiency or a geothermal heat pump at 3 to 5 times the efficiency. So adding one of these plug in portable electric heating units normally increases your family’s energy costs.

There could be one exception where you would save some money. If you can tolerate your home at a low (example) 55 to 60 degree temperature and then use a portable electric heater in a single, small room kept at 70, you might save some money. But this depends on the type of heating fuel and heating system you use. You may only break even for all the discomfort of a cold home.

One more comment. By electrical code, if the advertised portable electric heater plugs into a normal wall outlet, it can only be 1500 watts maximum. So it is never “more powerful” than the same 1500 watt unit you can buy at the local discount store for as little as $12.00. (That’s right, only $12. That’s not a misprint. Compare to the $300 and $400 price for the quaint, country built, rip off heater.) If you really need a little “spot heat” in your home and do not mind a little increase in your energy costs, look over the choices in the discount store and upgrade to a heater that includes several built-in safety devices. Read more on Portable Electric Heater Safety.

Or, your best solution for any home comfort problem, call Precision Comfort Systems. We are the heating specialists that tell the truth.

This has been my annual portable electric heater review and now I will file it away until next year. With the outrageous profits being made in this scam, I’m sure the ads will continue. By the way, your zip code, regardless of the number, has just been added to the list of zip code areas from which we are now accepting calls.

Time to close crawl space vents

With a name like EnergyManDan, you can imagine how frequently I am asked, “How can I save a lot of energy with minimal expense and minimal time invested?” Typical need. We all want the easy easy. Fortunately, there are a few energy saving measures  that are actually this easy and valuable. One great example is to close your crawl space vents for the winter. When I drive through neighborhoods, I cannot help but notice how many homes still have their crawl space vents open. This is a huge mistake in terms of trying to keep your home comfortable and your energy bills low during the winter. Here’s the scoop.

Home foundations are typically a basement, concrete slab or a crawl space. Of these, normally the crawl space is the only one with vents to the outside. Venting the crawl space is no longer a good idea in our energy efficient homes with heating and air conditioning ducts in the crawl space. These spaces under the home should be considered a “conditioned space” which means they are heated in the winter and “conditioned” in the summer. This post deals primarily with winter heating but here is another post about summer.

Think of your crawl space as a short basement. It should  be insulated around the perimeter on the inside of the crawl space walls which makes this a heated space in the winter. Many homes with a crawl space will have heating ducts in this area and these ducts perform best when they are in a warm space in the winter. Crawl space vents need to be closed, sealed and insulated to keep the cold winter air out of this area. Note that simply closing the louvers from the outside will seldom seal this opening properly. In addition to closing the louvers, you should go into the crawl space and seal the opening with a tight fitting plug and then add insulation.

Allowing cold air into an otherwise conditioned space can increase energy costs, cause the heated air in the ducts to be cooled, create cold floors and even add to the dryness of your home. If you close your crawl space vents and you are still having comfort issues, call Precision Comfort Systems. We are the home comfort experts in Noblesville, Westfield, Carmel and all other Indianapolis area communities. We discover the real reasons you are not comfortable!

Closing crawl space vents for the winter is an easy to understand energy saving measure. But what should you do with these vents in the summer? That concept is a more difficult topic and worthy of a separate blog or two. Fortunately, you’ve come to the right place for the answers to these questions. Here is more information on summer moisture problems from crawl space venting.
