"I’ve had the pleasure of working with Bill and Cool Air Technologies on several occasions and they never disappoint. They’ve done a HVAC replacement as well as an entirely new HVAC system install with impeccable results. They were professional and communicative; answering all my questions and working through any issues promptly. I will look nowhere else for my HVAC needs and highly recommend them to anyone considering their services."

"This review is about Air Duct Professionals and I want you to know that I finally found a company that was honest and professional. Because when I was at the end of my wits trying to figure out who was telling me the truth, I called Ed Mack the owner and he was reassuring that my home was not that old to be having all these problems. He referred me to a website for the Air Duct Cleaners Association and read about what air duct cleaning really does. So I had Air Duct Professionals come out to the inspection and they have an actual HVAC guy on their staff. Immediately looking at how new and well maintained our air system was in the attic, he told us those other companies were trying to scam us. Air Duct Professionals did a great job cleaning out all of our air ducts and dryer vent and cleaning up after themselves. I whole-heartedly recommend this company for their professional work and honesty."

"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!"

"Sam, who came out to give me an estimate for a new system, found out that the old fan motor was the culprit and recommended that we just repair the motor. He explained things in detail, helped us to save money in a genuinely sincere attitude, I was impressed how good his service was, and I recommend him for any HVAC issues. I will be using him in the future."

"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

Heating and Air Conditioning questions, answered by experts

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.
