"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 just moved to New Hampshire from Connecticut so I use HomeAdvisor which listed McGinley and Sons. I saw all FIVE STAR ratings and I'm giving them the same only because I cant go any higher or it would be 10 stars. The business owner fully explained to me in my home during the quote what would work best in my condo. The crew (sons & coworkers) were an amazing team to watch at work and since I am retired manufacturing production manager I know when team works and knows exactly what they are doing. The most important thing I can say is they are all experts in this HVAC field. The task I had was to install a split unit installed, 2 heads, 18000 BTU living room & 7000 BTU in the master bedroom in which everything was done in less then 1 working day. Trust me, this is who you want if your questioning who to hire for your heating or AC job. My Thanks again McGinley & Sons, I thank you for a job well done above our expectations."

Heating and Air Conditioning questions, answered by experts

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.
