"I hired Onofrio to replace my gas furnace and install a new AC unit. A few months later when I had a minor gas leak in the pipes (unrelated to their install), they came out within a few hours to fix the leak. What REALLY impressed me was how they came to bat for me when the gas company initially said that it could be as long as next day to turn my gas back on after the repair. This was during the coldest days of the winter and I was very grateful that Onofrio stayed invested in me until everything was remedied."

"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."

"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 FAQs, answered by experts

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

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

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.
