"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"We were very pleased with the work that the Genove technicians did. They removed our 40-year-old gas boiler and associated water heater and replaced it with a new system. They tested the new system carefully, put explanatory tags on all of the relevant pipes and faucets, and cleaned up well. The team members were polite and worked hard. We had similarly good experiences when Genove technicians came to repair our central AC system. They were knowledgeable and efficient, got the system going again, and the price was fair. We continue to use this company for heating and AC repairs."

"We could not have been more pleased. We needed to replace our first floor AC, which is a split-type ductless system, about 17 years old. We had an idea of what the cost would be from an online site: [*** Link removed ***] We got 4 bids, 3 from A rated Angie's List contractors to install a Mitsubishi system (top of the line). Except for one, which was off the charts, the bids weren't that far apart. While Unique was not the lowest bid, we chose them for three reasons: (1) Jason (their rep) was the most savvy about the Mass Save and Mass CEC Air Source rebates, which were quite significant (he handled all the rebate paperwork for us); (2) Unique was able to do the job in a week; and (3) Unique included all the electric work into the total bid (rewiring was required). The installation team (John and Quinn) was excellent. It took them a day and half, They were quiet, neat, professional, highly respectful of our homes and proud of their work. We had worried that they would have to remove wooden ductwork which had been recently painted, but they managed to snake the new hoses through the existing ductwork without disturbing anything. Unique had an electrical contractor on site who replaced the breakers on our electrical panel, installed a higher capacity wire from the panel to the AC system, and replaced the cutoff switch on the outside. We were quite pleased with Unique's work, and would definitely recommend them to others."

"Morris Heating and Air Conditioning staff quickly worked me into their schedule even though I was not a current customer. Service Pro Christos called when he was in route. He walked me through his troubleshooting and diagnosed incorrect wiring left by another HVAC service technician during furnace work in the winter. Problem resolved in 10 minutes. I am a Morris Heating and Air Conditioning customer now."

"I have a two-story single family house. Last year, Druziako HVAC replaced my first floor AC with a Carrier heat pump. I quoted 5 companies, and Druziako was honest and gave me best pricing. The heat pump worked great in summer and winter. This year I hired them again to replace my 2nd floor AC. The whole team are friendly, helpful, and very patient. Installation went smoothly and quickly. I cannot be happier with the pricing and quality of the work. I will recommend them without any doubt. Thank you very much!"

"It was quite a surprise to find black mold growing in our mini-split heat-pump/ac units over the weekend! The situation was quite dire with the system emitting a bad smell and the fact that I have asthma and mold allergies which posed a serious health risk! After being told by the company that originally installed the system, “We don’t provide deep cleaning service for these units, try looking on Angie’s List (boo on Sila!)” I landed here. While other companies did respond to my bid, Atlantic Heating and Air Conditioning was the most responsive and was able to send out a team on one day’s notice (the wait for other service providers was up to three weeks!). The tech team, Josh and Zack, arrived on time and called me 1/2 before arrival as promised. They were very respectful, kept a clean work space and (since we are in the middle of a pandemic) wore masks and were very careful about the usual COVID protocols. The four units in our home are now SPARKLING CLEAN! We are 110% pleased with this job!! We will hire Atlantic as need be in the future for our heating and cooling needs. I have given up on the company that originally installed the units and will post a truthful review about them in an appropriate space online. I would definitely recommend Atlantic to family and friends. (photos attached to this review show one of the units before cleaning - did not think to take after pictures. Suffice it to say, no more mold:)"

"Peter and Mark were very professional. I needed to replace the HVAC dampers and the communication with Peter was excellent and we had all questions answered ahead of time so we didnt have any last minute surprises. They showed up on time and installed the dampers and the HVAC control panel. Very thorough and clean with their work. I've already recommended them to my neighbors."

Air Conditioning FAQs, answered by experts

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.
