‘Tis the season!

August 26, 2011

It’s that time of year again!… Or is it?… It’s time to start thinking about the winter and whether or not your furnace is going to make it through! I know it’s been one of the hottest summers we’ve had in a long time and most people are reading this going “are you kidding? Why would I be thinking about heat right now?”. The bottom line is; if we have as cold of a winter as they are predicting, everybody is going to be calling at the same time to get an estimate on replacing the furnace. Because, as most of you know, it never fails; your furnace will go down at the same time as everybody in Central Indiana.

Furnaces have really come a long way. They used to just be that “box inside”; but now they are so much more. What with variable speed blowers, multi-stage heating, extremely quiet operation, and so on. You’re getting much more than “box” that blow heat through your home. You are getting the “brain” of your home comfort system. The furnace controls the volume of air, heat, and dehumidification that is delivered to your home. Variable speed blowers are a no brainer when you are replacing your furnace. They are able to ramp up or ramp down depending on the temperature levels in the home. In the winter you can get “cold blasts” of air with your typical “single-speed” blowers; variable speed blower eliminate this because they are constantly circulating the air in the home and keeping a “more average” temperature. It’s kind of like cruise control for your system.

When you hear people talk about multi-stage, two-stage, and single-stage heating; they are referring to how many levels of heat the furnace has. The best way to explain this is; a single-stage furnace will put out 100% of its capacity 100% of the time. A two-stage furnace has a low setting and a high setting for heat. On mild days, a two-stage furnace runs at a lower capacity (1st stage) to take the chill off. When 1st stage can’t keep up; it goes in to 2nd stage. Multi-stage or “variable capacity” furnaces work much like the cruise control system of high-performance automobiles, automatically making adjustments as necessary to allow maximum fuel efficiency. They typically start at 35% of capacity and can ramp up or ramp down in 1% increments.

There are so many options out there. Make sure you contact the professionals at Control Tech when you are ready to make a decision. Keep in mind most estimates require 60 to 90 minutes to properly size a system for your home! We can’t make a 20 year decision in 15 minutes! When you call; please ask for me or mention this article!

Control Tech gets some new “additions” to the family!

June 22, 2011

For many years, Control Tech’s “Comfort Consultants” relied on driving their personal vehicles for work. In June 2011, we decided to change this. We have added 4 Chevy Cruze’s to our line-up. We felt as though this would give our customers a better piece of mind when they opened their front door and were greeted by one of our Comfort Consultants; they were able to see a clearly marked Control Tech vehicle in the background. Much like the products we provide; these vehicles are fuel efficient and sleek. As always, we strive to be the best at what we do and we continue to improve ourselves every day.

It’s so humid in here!

May 25, 2011

It’s that time of year when we start getting calls about the home feeling clammy, yet the air conditioning is working fine. People start spening all kinds of money on portable dehumidifiers in the local big box stores. The problem is; they usually only take care of a small area or room in the home. What if you could dehumify your entire home for a fraction of the cost that it would cost to buy a bunch of portable dehumidifiers?

We provide several options for dehumidification; most of which can be installed directly into your duct system to dehumidify the entire home. Otherwise, some of the units can be used as a stand alone and remove up to 135 pints per day which is 50% more water per kilowatt hour than the leading portable dehumidifiers!

There are several ways to help dehumidify your home by simply installing the proper furnace and air conditioner when it comes time to replace them. The first item that will help reduce the humidity in your home is a variable speed blower on your new furnace. First off, when the fan runs at a lower speed, it has a better chance to pull moisture out of the air since it is moving the air at a slower speed. Plus, the longer the system runs, the more moisture is removed. Second, a variable speed blower only uses as much energy as a 75 watt light bulb to run, while a traditional “single speed” blower uses 700-750 watts to run; so there is huge energy savings! Lastly, with a variable speed blower, it does a better job of filtering the air since the particles are constantly moving at a slower speed the filter is able to catch more of the particles and dust; which can dramatically improve the indoor air quality in your home.

When you are looking at getting a new air conditioning system; consider what is called a “2-stage” air conditioner. It’s like having two systems in one! These air conditioners will run at 67% of it’s full capacity 80-85% of the time when you need cooling, but the temperature outside is moderate. Then, it can run at 100% of capacity on those “hottest” days of the year. The great thing is, when it runs in the lower stage; it only consumes 1400 watts of electricity. In comparison, it’s like running a hair dryer. When it has to run at 100% of capacity on those hot days; it consumes approximately 2200 watts of electricity. Keeping in mind, a typical “single-stage” air conditioner runs at approximately 2200 watts all the time.

The bottom line is, the slower we move the air, the better the dehumidification. Also, the more efficient your system is, the more money in your pocket!

So… How Much is a New Air Conditioner?

April 13, 2011

This question may be on your mind this spring or summer. Especially if yours is not cooling and its 95 out. Well, before I answer, I’d like to ask a few questions. What is your average heat gain in the summer? What is your peak heat gain? What are the dimensions of the indoor and outdoor units? What is the size of the suction line? The vapor line? The distance between indoor and outdoor units? The wire size? Breaker size? Where does the condensate exit? Do you know internal friction rate of your duct system? What is the latent load requirements of your home?

Ok I could go on, but the idea is there are several things that need to be taken into consideration when selecting a new air conditioner or comfort system. That is why a visit from a trained professional to look over your home is necessary. In the old days it was sometimes acceptable to just put in a box that gives you cool air in the summer and another box that gives your warm air in the winter. With high energy costs and expensive materials, it is more important than ever to have a system that keeps your home comfortable, your energy cost low, and runs reliably for many years. The new way is to give you a customized comfort system, matched to your home and your needs; installed by people who understand the reasons for doing things a certain way.

So, back to my question, how much is an air conditioner? Send us an email or give us a call! (Clay) clay@controltech.biz 317-873-3737

Free Energy!

March 31, 2011

Where would you keep your thermostat if the utility companies decided not to bill you this year?

If you are like me, you’d probably keep it a bit warmer over the winter and a bit cooler over the summer. You and your family might take longer showers. You might get a garage heater, or a snow melt system for the driveway and the porch. You might not be so concerned if the kids leave the lights on or come in and out the door all day.

Have you or anyone you know ever gone on a stay-cation lately due to high gas prices?

Energy cost can have a dramatic effect on our lifestyles and habits. That is one of the great hidden benefits of a high efficient comfort system. Geothermal & solar offer extreme reductions in the amout of energy it takes to heat and cool your home and provide hot water. So extreme in fact that you can change your habits and still see huge reductions in the monthly bills. For the more conventional person, gas furnaces come in efficiencies up to 98%. Compare that to the old 80% furnace in most peoples homes and you can keep it warmer and still save. Heat pumps and air conditioners are the exact same way. You and your family can be more comfortable and keep a bit of your hard earned dollars in your pocket instead of the utility company’s.

 You can also make a difference to the planet. Installing a geothermal system in a 2,000 square foot home is the equivalent of planting about 20 trees per year; reducing your carbon footprint. You might not get a Nobel prize but I think we would all like to be good stewards of our Earth.

Many people will have to replace thier air conditioners this summer due to failure. That is an obvious opportunity to investigate a high efficient comfort system. I will be out there to replace your air conditioner and get you cool, but I will also want to tell you how much more comfortable you can be with a high efficient system. Even if your current system is not that old, you can see how much you’ll save with our new energy savinigs calculator below.

It Gets Late Early Around Here

March 23, 2011

               My dad used to say that before daylight savings time. Since central Indiana has adopted daylight savings time, now our air conditioners have the greatest demand later in the day. For many people, the air conditioner works its hardest right after we get home from work when we want to be comfortable. Often times this is also when we are cooking, doing laundry or going in and out the door. Sometimes the demand is as much as 40% greater at that time than the average for the rest of the day. To make the problem worse, most existing air conditioners are either working or not. They are unable to adjust to the changing demands of our homes throughout the day. Some new comfort systems have two stages or more to adjust to the demands of your home. Combined with variable air flow, these systems are like two air conditioners in one. One very efficient and small air conditioner for the majority of the time, and another large air conditioner for those evenings when the heat, humidity and people in our homes can make it very uncomfortable.
