"Donny and his team are the best, They installed a new HVAC system for us in the Fall and made some updates to our other systems. When we needed help with a fan noise issue they came out quickly and fixed the issue with really creative and innovative ways of problem solving. Incredible."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"Excellent service. Very prompt. Called Mike and he came out within a hour. Mike is very experienced, having dealt with many HVAC companies, these guys are tremendous. New exactly what was wrong and fixed it like a professional. Cost was better than I even expected. Forget the others and call MTL. Iâ ll be using them from now on."

"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 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."

Heating and Air Conditioning FAQs, answered by experts

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

It depends on the specifics of your warranty. The motor is likely not covered if you’re working with a limited warranty. The same goes for other components like the compressor and evaporator coil. Some extended warranties will cover the blower and fan motor, so read the fine print before signing up. Additionally, the manufacturer may offer a warranty for the parts, including the motor, though there’s likely to be a strict time limit for this coverage.
