"Bill called me first thing in the morning (7:30) after I sent out a request very late the night before. I had one others HVAC contracter make two trips to my home but could not figure out the problem? Bill had two of his tecknisions come out that morning but the problem still eluded them. The next day Bill came to my house and within 10 minutes he had it figured out. He explained exactly what the problem was and got my furnace up and running at 100%. He called back that night to check with me and make sure. Everything was OK."

"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 highered Bruce and his team, we're very happy with the service. They installed a couple new baseboard heaters to our existing unit to add more heat to a few rooms that's were cooler than we liked. We're very happy and much warmer. Bruce and his team were responsive and open to everything they were doing. Fast and efficient highly recommended!"

"We received professional and detail-oriented service during our complete HVAC installation. I couldn't have been more pleased with the quality of work and price! There was a mix up with the new furnace and the owner rectified it without question. While they were here, I received a quote for connecting a stand-by generator for propane, and the owner noticed what I have been extremely nervous about for several years, which a well-known company that is in Salem and rhymes with Slicer had installed new gas piping in our basement using plastic flexible pipe and several regulators. We have been smelling propane in the basement ever since of which Slicer was not able to rectify. Thank goodness for Quiet Corners! Now all the gas piping is black iron, and there are no more regulators in the basement; hence I am no longer scared about our house blowing up! My wife also noticed that the gas burners on the stove light easily now and produce an excellent flame (she was afraid to use our stove previously). Great service all around, and prompt attention to detail. The service crews were fantastic and took great pride in their work. I can't thank them enough for the outstanding job they did at our home. We now feel safe, warm and comfortable. :-) I plan on being a loyal customer and fan of Quiet Corners for many years to come!"

Heating and Air Conditioning FAQs, answered by experts

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

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.
