Supreme Air did an amazing job installing this new Fujitsu mini-split system. They worked all day Sunday in the blistering heat to ensure we had AC that night. They are reasonably priced and their knowledge about mini-splits is second to none. I highly recommend them without hesitation.

"Charged $2,000 (that's right, $2,000!) to install a new sprayer faucet and soap dispenser in Boston. $1,500 went to labor, which took less than 2 hours. I'm sorry, but $750/hr is outrageous. I did pay it because I wanted to expedite solving the problem for the tenants, but I now regret as their dishwasher is not working and I suspect the plumber failed to reconnect everything probably."

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly.

"I was told that the fee to simply come into my house to assess my furnace (that was not working) would be $260 on a Wednesday afternoon... and I was told this fee would not be absorbed into the work if I chose to have it done. If this company charges such an exorbitant assessment fee, I could only believe they would inflate other fees as well. I hired another local company for half that fee to assess then repair my furnace. Shame on Heritage Home Service."

"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

Heating and Air Conditioning questions, answered by experts

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces.

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak.

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

To make the most out of your AC, consider implementing the following best practices:

Choose the right size AC for your home to ensure your unit runs as efficiently as possible.
Choose a window with shade, as direct sunlight can cause your AC unit to overheat.
Clean or replace the filter at least every two months.
Inspect the AC’s fan and straighten it if necessary.
Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues.
Turn off (or adjust the temperature) when you leave the house.
