"Exceedingly STELLAR work; BEYOND professional decorum elicited by the company’s OWNER AND staff MEMBERS (specifically the technicians that performed the installation). Overall, we HIGHLY recommend this company to neighbors, family, friends, coworkers & even strangers in our community that may be in need of any HVAC or others services for their homes and/or businesses. Financially, they were on par with our anticipated costs for the work we needed done. FAST, QUALITY WORK that we’d NEVER hesitate calling on again for any future needs that this EXCEPTIONAL, ‘5-star worthy’ company provides! Thank you especially to Ron, Carlos and Brandan… we truly enjoyed meeting you and the pleasure of your company while you worked diligently in our home was all ours. Perhaps this review seems “over the top”or contrived, but we truly wanted to reward this company properly with a review that sufficiently and congruently matched their “talk with the walk” behavior. As you (a co-consumer) know there are so few these days that that elicit good, old- fashioned business ethics. We want you to know this was honestly a job TRULY well done!"

"Very knowledgeable owner-operator. Prompt and personable. He repaired our 30-year-old central ac unit and did not try to upsell us to a new one. He was very thorough in his inspection of our system. I will use him again when we decide to replace our ac."

"I wanted to clean a second floor dryer vent hose that was loaded solid with lint. It was worse than I thought! Packed solid! It became evident that this was a messy and dangerous situation as it was a fire hazard. Through Angi I found Everclean and the co. was a perfect fit. HVAC companies don’t do dryer vents. Justin from Everclean was awesome and got the problem straightened out. He even discovered the dryer vent had become disconnected from outside dryer vent door! I can’t fit through the narrow attic hatchway as my shoulders are a bit too wide, so I depended on Justin. Finally, everything is buttoned up, and our clothes now dry in half the time. Cost was moderate and was money well invested. Dryer vent fire danger is now negligible compared to before. Along with neighbor hatred danger. I would hire Everclean again if needed again."

"I needed an HVAC company for both my heat pumps. for house and garage shop. I looked on Homeadvisor and found Bill Aitken Heating. Thank you Homeadvisor! Bill was not only professional, but friendly and courteous. He explained everything he was doing right down to how the newest equipment he used. Bill was very thorough checking out my HVAC system. I will need to look no further for a contractor due to Bill's excellent work. I highly recommend Bill."

"I turned to finding a dryer vent contractor on this website when I was unsuccessful in finding one through Google. Either the company didn t call back or didn t show up. My current HVAC contractor stopped cleaning dryer vents. When I began the search, it was very late at night. Y&M Airduct Service phoned me the very next morning. They were rated very well and see why. They are honest and explain everything in detail. There were a few things I knew that needed to be addressed, such as the attachment to the hose behind the dryer and the vent that had been broken to the outside of the house. Everything has been fixed and/or replaced at a very reasonable rate. Not only was this experience very positive but have decided to not renew my contract with my exiting company that I ve had for over 10 years. I will be having Y&M perform all of my HVAC needs. If you decide to hire Y&M Airduct Service, you will have everything done right the first time. No hidden agenda, no hassle and piece of mind knowing one less item is taken care of."

"Seems the basic cleaning does not work well for my situation. Noticed lots of loose dust ball around opening of vents right after service is done. The promotion price is good. But feel the work to replace missing dryer cap is expensive. Technicians are helpful and knowledgeable."

Heating and Air Conditioning questions, answered by experts

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it. 

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.
