"Early summer we had problems with our A/C system. Kenny and several other employees responded quickly and resolved several problems with our system. He ordered a new part and returned promptly to install it."

"Just too expensive for what you get. Feels like a big company nickel and dime move. I get having a trip charge. Which was $109. But then to have the tech who was great btw (not his fault), but was tentative about fixing the problem because of creating more damage. Another $160 for a simple diagnostic charge, again without fixing the problem. I already knew the diagnosis. So he basically did a Band-Aid fix (greased the Knob) and still charged me over $280+ for what equated to be 10 minutes of work. It was ridiculously high for the service provided. Next time I?m going to an independent, local guy."

"We had Sean and his team install a full house ductless heat pump system. I cannot recommend them enough. They were friendly, organized, efficient, and were sweet to my zoo of pets. Their work was done beautifully. I am picky about placement and how things look and they knocked it out of the park. I’m very happy with the job they did."

"Wood flooring and so much more. Carpets torn out, subfloors repaired, including work at doors and windows. Impeccable attention to detail. No threshholds, smooth perfect and tight seams from room to room and door to door. I love a crew that doesn't have to hide their transitions under a threshhold. Work ethic--- amazing, here on time, every time, every day. Added on recessed ceiling lighting in 2 rooms and ceiling lights in all rooms. Brutal attic work on over 100 degree day. Seamless experience in every way. They clean up the site at the end of every work day. They haul away whatever needs hauled away. They are friendly, talented, welcome input and do what needs to be done to exceed all expectations. (there were none!). I have more jobs scheduled: decking (including relocating propane tanks), house addition, complete renovation of two bathrooms., fencing. My go to crew for everything."

Heating and Air Conditioning FAQs, answered by experts

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

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
