"These guys are great. They came to assess the situation (problems with our oil furnace) and thoroughly reviewed options. We went with them for a furnace replacement, as well as a heat pump to replace our standard a/c units. They came in much cheaper than the two other companies we consulted (one of which we had used for almost 50 years (since the house was new). We're thoroughly happy with our new HVAC setup, and even the fancy Nest thermostat. Highly recommended!"

"Sila installed a new Lennox HVAC system 2 years ago and when there was a leak today they showed up within hours! Not like some places that would have many excuses and complain about Fri being too busy. Their Tech Calverton is a special tech, knowledgeable, polite and willing to go the extra mile. Not only did he fix the leaking problem he took his time to adjust dampers to ensure all rooms are toasty! This has always been a problem for us and not fixed until now. It takes a patient problem solving tech to make a happy customer! A special thanks to the service manager ,Doug Bines , who always seems to help when needed."

"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."

"They installed central air conditioning in our house. They gave us the best price for what we wanted. Their installing technicians were extremely careful, clean, helpful and quiet. They installed a whole house  (2 floors) system with 12 registers in 3 days. The air handler was installed in the attic and compressor was installed outside. I would recommend them to my best friend and I would use them again if I move to another house."

Heating and Air Conditioning questions, answered by experts

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.
