"From the very beginning, Lonnie in sales provided me with a first class presentation and quote. The installation was scheduled and Steve, Dalton and Bob were on time and the job was completed in a timely fashion. The work was performed in a professional manner and they took the time to answer any questions i had. I might recommend Wade Heating and Cooling for all your HVAC needs"

"We hired Bactronix to clean the HVAC ducts in our house. Technicians Masson and Shawn arrived on time, did their work unobstrusively and efficiently, and answered all my questions politely and fully. They sent over before and after pictures of the ductwork by e-mail afterwards. Their work has made a positive difference to the air quality in the house, and we appreciate their services."

"My air conditioner stopped producing cold air Saturday evening, but I noticed so late that I had to wait until Sunday to try to get it fixed. I called the company I typically use for my HVAC and was told it would be $230 for them to even come to my house because it was a weekend. I completely understand a weekend being overtime, but I didn?t want to pay the additional fee so I told them I could wait until Monday to have it fixed. A technician was supposed to call me back to schedule a time for them to come on Monday, but they did not end up returning my call on Sunday. While I waited for the other company to call me back, I looked at Angie?s List to see if there were any highly-ranked companies I could use instead. John Mullen Home Repair was one of the companies I had planned to call Monday, but I noticed the hours said they were still open so I called at 6:00 PM on Sunday, fully expecting to schedule them to come Monday. John answered and said that he was on another job that he expected that to wrap up shortly and that he had another stop to make after that, but he thought he could get to my house around 7:00 PM. At this point it was about 85 degrees in my house with all the windows open, so I agreed to have him come out even if it meant an additional weekend charge. Around 6:45 PM I received a call from an employee of John?s saying he would be at my house in about 15 minutes. In talking to John, it seemed like he was going to be the one who came to my house, but I?m assuming he ended up sending someone else because he would have gotten to my house later than his estimated 7:00 PM. Having had to wait many hours for various service people to show up for their appointments, I was very impressed and pleased that they cared so much about meeting the appointment time. He showed up right around 7:00 PM and almost immediately diagnosed the issue as a blown capacitor. My air conditioner is fairly old and has actually blown a capacitor before, but the previous time it broke I used my typical HVAC company who charged me $250 for the capacitor on top of the labor and additional weekend charge (because of course it broke at the beginning of a 4-day holiday weekend where every day was in the 90s). The guy from John Mullen charged us $100 total for the capacitor and the labor. I was very pleased with that as well, so I mentioned that I?m probably going to replace my AC unit sometime in the next year and would be interested in using John Mullen. He said he noticed that the unit was older and that we could probably just run it until it dies, but explained a few of the newer units they have and the pricing for those. He wasn?t pushy at all and didn?t try to sell me on anything immediately, which I appreciated. To summarize, it took John Mullen Home Repair about 1.5 hours from the time I called them to the time they left my house after fixing my air conditioner, all for $100. I am very happy and would definitely recommend using them."

"A great company, from the estimate to the install they were on time, informative and very professional. I really think I could not have found a better group of professionals to replace my current heat pump and air handler. Kudos to this company, I highly recommend you give them a shot at your HVAC needs. If their service is as punctual and professional as they have been for the install, I'm not sure you could find a better fit. Thank you Air Systems Mechanical and please say thank you to your team of guys for me who installed my system, they were outstanding! I found my go too for all my HVAC needs."

"They installed our HVAC system two years ago and they service it every 6 months. We have the furnace checked in the winter and the air conditioner checked in the spring. They are very reliable and professional and they do a great job."

"Very professional and high-tech serviceman. He did not rush. He took the time to diagnose the problem with the heat exchanger in our furnace. We have a very old furnace in a property we rent. He made us feel comfortable the furnace can make the winter. Would highly recommend Kennilhan. Great company."

Heating and Air Conditioning questions, answered by experts

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.
