"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"

"I emailed several places and they called me within the hour to talk me through the whole process and made sure I understood everything in my own terminology. Their prices were super competitive that it was a no brainer to scheduled them on the spot without other comparisons. My technicians Bob and Bret were super friendly and were very professional. Left no mess, updated me when needed and gave me advice on how to keep it clean throughout the years until the next recommended service. Overall we are very pleased and will be coming back to them for future HVAC Cleaning needs!"

"Would absolutely recommend John Mullen and his company. From the first time I called John he was very responsive and professional. I had called multiple other HVAC companies to install a vent through a brick chimney and were having trouble finding someone who would even come take a look to see if they could tackle the project. John didn't hesitate and came out and talked to us to find the right solution. Once we were ready for the job we were able to schedule him within about two weeks and he called the day of to see if they could come a bit earlier than planned. I truly appreciate the quick and professional communication throughout the whole process. The guys that came with him to do the work were also professional and they got the job done quickly. The price we paid was very reasonable for the length of time they spent and the difficult job of drilling out through brick."

"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

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.
