"I had a great experience working with Cool Air Technologies. Bill and Trish McIntosh are fantastic. Great personal service and super friendly. When I first met Bill, I explained to him that I had recently purchased a new home and was in the process of making some upgrades to my existing home so I could covert it to a rental. I didn't have any air conditioning so that was my priority but I was considering replacing the original furnace at the same time if the price made sense. However, I didn't want to invest in a high end system since I wasn't going to be living there myself. Bill quoted me a great price for the A/C and new furnace so it made financial sense to do them both at the same time. One of my other quotes was literally double for the same scope of work. Bill came in with his crew and they were professional and efficient and completed both A/C and furnace installs in about 7 hours, including running all new piping and electrical for the A/C. I would absolutely recommend Cool Air Technologies and the personal service that Bill and Trish provide and I will definitely be giving them a call in the future for my new home. Thanks Bill for the great work!"

Customers say: Quick response

"I was out of town when my air conditioner stopped working. My mother called 2 companies to check it out. The repair men were interested in selling us a new unit not fixing it. I found NT Electric & HVAC online through Home Advisor while I was out of town. The company had good reviews. I called Nathan and scheduled an appointment. He assessed the problem and fixed it! I would highly recommend Nathan and his company. He does what s best for the customer. His prices are fair and reasonable. I would use him again."

"Unfortunately, I needed an HVAC company to fix my AC during a heat wave. Most companies were 5+ days out before they could even diagnose our problem. Called 3 highly visible companies, from their marketing, who said they wouldn't even work on our unit. I went with a referral from a neighbor, mistake. This company took a week to get to us then the tech went MIA for 5 days with no contact when he said he would be back tomorrow with parts. Won't mention their name as there could have been multiple uncontrollable reasons why. I then did a lot of research on different companies across multiple review websites (including Angies) and Excel Air stood out. Once I spoke to the office staff, great experience, they had a tech out to our home in 2 days with our problem diagnosed. Our tech's name was Lucas who was efficient with his time, talked me through what was going on and gave us our estimate which we were happy to move forward with. Lucas fixed our problem in under 20 minutes. Me being me, I watched each step and saw the quality work. He even put in a fuse to ensure the same problem didn't happen again to our transformer. Once he fixed everything and got our new thermostat power, our AC has been working perfectly ever since. I'm now a really big supporter of Excel Air. Their office staff worked with our insurance company after hours and actually updated us (what company does this these days) the entire way. I can't tell you how impressed I was from their office, Lucas and most of all their successful resolution of our problems with our AC. Thank you Excel Air!"

Heating and Air Conditioning questions, answered by experts

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.
