"The guys that installed my central air (and ductwork) were great to work with. They worked with me to get the system installed the way that I needed for extra storage space in my attic and were very pleasant and took care of my home. They also gave me a great deal! I would happily work with them again."

"We came home from an outing on a Sunday night and found our air conditioner not working. I found John Mullen on Angie's list and liked the reviews. I contacted John and he asked me about my schedule on Monday. He fit us in on Monday morning. I wasn't home but my wife was. She said that John was so nice that she assumed that he was a friend of mine. I told her that I never met him before. He fixed the air conditioner and I am relieved that it didn't cost us a ton and we avoided 85 degree heat with an air conditioner. I would use John again. He was dependable, came out with in 12 hours of being called, and my wife does not always comment on how nice someone is unless it is absolutely true. Thumbs up for John Mullen, I have just found a go to guy for everything!"

"We have worked with Jeff for years. He has previously installed full furnaces and air conditioners, and two prior mini-splits at our house. He just used him again to install a third mini-split. As always, he was responsive and easy to work with. His crew are very polite and professional. They work very cleanly, leaving no dirt at all in my daughter's room after installing the mini-split. They balanced the needs of the equipment well with our desire to conceal any lines as much as possible. I would absolutely work with Jeff again."

"Mr. Sullivan was very knowledgeable, helpful, and prompt. I had a broken valve on one of my radiators and it was replaced in no time. He arrived at the time he said he would and completed the repair work in a timely fashion. I would highly recommend his services to anyone. He said I would have heat by the time he was finished and I did. Thank you so much."

"Highly recommend Kenders HVAC! Both our furnace and air conditioner broke down at the same time, which was a huge stress, but the team at Kenders handled everything flawlessly. They showed up right on time, gave us a very reasonably priced quote, and managed the entire process from beginning to end in less than a week. Their team was professional, efficient, and left everything spotless. If you want honest, high-quality, and fast service, look no further than Kenders!""

"Water had been pooling in front of my garage by the storm drain.  I called and they were able to come out the same day.  The service technician confirmed that the drain was blocked by ice and that the water would eventually stop pooling when the ground/ice finally thawed after the long cold winter we had experienced.  Weeks later it thawed out.
The technician was polite and answered all my questions. I would recommend this company and have continued to use them.

"From the beginning talking with Chris to the end the process was amazing. Carlos Frank and Brenden arrived on time, removed and cleaned the all the registers, and of course the air ducts. A problem arose that was not caused by them, but the AC had an issue and they stayed as long as it took to resolve it. Paul was a huge help during this and even followed up in the evening. Phone calls were returned promptly, questions answered without hesitation and problems resolved! I haven't seen this from any company in ages."

"New furnace and AC installation. Shaun and his crew did a great job installing and the cleanup. The cost of the installation was very reasonable. One very important thing was Shaun and his crew interacting with me, the customer. Thank you Shaun, Rob and Bryan (Squirrel) for a job well done."

Air Conditioning FAQs, 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.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.
