"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."

Customers say: Quality work

"I'll start by saying that I have severe allergies. and respiratory issues Jason and Mike were not only NADCA certified, but friendly, knowledgeable, punctual, and most importantly... honest. I had spoken to others that said they would "fix" it", but Cornerstone came, evaluated my system and, rather than charge me unnecessarily, they provided me with other options that they did not even offer. That's service!!! I look forward to scheduling them when my system is actually DUE for a cleaning. Thanks gentlemen!"

"When we were ready to build a new house, we had intended to install a geo-thermal system because of its extreme energy efficiency, but when the bids came in, the cost was too high. On the very day we were researching what our next best option would be, Bill McGinley (who we had interviewed a month before, but who does not install geo-thermal) called out of the blue with an idea for us to consider. He was at that time installing his first two Acadia Cold Climate Heating and Air Conditioning heat pump system, and thought we should consider it. He gave us the website, and we did our research, and it was exactly what we needed. About the same energy efficiency as the geo-thermal system--at one third the cost. We hired Bill. Bill and his team worked in brutally cold, windy and icy conditions to get this complicated high-tech system installed. Also, because our timeline was left short because of the repeated weather delays, they had to do it all with the carpenters, electricians, plumbers, insulators and me all underfoot and in the way. Yet they were friendly and accommodating toward everybody and kept the environment upbeat and amiable. Which is not to say the job was without its surprises and obstacles. When Bill got a better idea of the size and shape of the house, and how well it was insulated, he downgraded us to a smaller system that saved us more than $2000. But, then that same super-tight insulation also required us to have an air exchanger installed to keep fresh air flowing through the house. They installed that, and still came in well under-budget. I have to say, though, that through this house-building experience, I learned a lot about just how badly the building industry is hurting. Most of the companies bid low and campaign hard to get the contract, and then charge you frightfully high time-and-materials for every little thing they can convince you was not part of their contract, and those bills don't come in till near the end of the job, destroying your budget and your trust. Not Bill. If a change was no big deal, he just did it. Even for some that were a big deal--like having to move the air exchanger exhaust vent because the building inspector did not understand that it was simply exhausting house air into the garage--he did not charge extra. If a really costly change had to be made (like the air exchanger), he could be talked down to a price that made me feel better about it. When I decided to make a change--like expanding from two to four zones, Bill gave me a great price. If I had a complaint of any kind, Bill would talk it through with me until it was resolved to my satisfaction. Bill has been back several times to tweak the system (or reset it when we failed to read the instructions. He is unshakably patient, kind and cheerful. We could not be happier with McGinley and Sons and would enthusiastically recommend them without reservation."

"I hired TCC three weeks ago to install a heat pump mini-split systems for my 4 BR home. Their quote was competitive, their install went as planned, and the technicians were super knowledgeable and worked hard to do it right. I am thrilled with the results. I have recommended them to family already and TCC will get more business."

Heating and Air Conditioning FAQs, answered by experts

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air
