"Gordon, Harrison and Louis did an absolutely fantastic job with installing a brand new HVAC system into my old house. The house was not designed to include AC so they had to be very thoughtful in the process of figuring out the best way to install all the equipment. They were on time every day and always kept me informed any issues and next steps.. They did it and we will enjoy the benefits of keeping cool this summer."

"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!"

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."

Heating and Air Conditioning questions, answered by experts

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.
