"My review for my service representative & the company MAXAIR LLC. Steve, was my representative for the service call and he arrived within the time slot that I was given. He was a very helpful & a nice guy. He got my humidifier working. As the digital panel had a light flashing to replacing the water panel on humidifier. He had the filter with him so he was able to replace the water filter panel. I set up a full service call on my furance. I was glad that I did that to get my furance ready for fall/ winter. He said showed me where to replace the furance filter. Then I decided to take advantage of the service plan that they offered. I was very pleased with my results through Maxx Air and Angi's List to help with my humidifier/ furance problem. Now I will be all set for my next visit."

"They did a great job installing a new hot water heater in 2015. In 2021, I noticed water at the base of the tank (possibly a problem with the drain valve). I filled out the online service request form but did not hear back. In the past three weeks, I have called the service line, and cell phone number listed on their profile several times. I was able to leave a message once (approximately two weeks ago). All other times the voice mailboxes have been full. I have not received any response to the online service request form, nor the phone message I left. It is disappointing and frustrating to spend 1k on a hot water heater, but then simply not to be able to reach anyone or get a callback. If the business is shuttered or overwhelmed for any reason, it would be professional and appropriate to post a message to that effect, at the very least."

Heating Oil questions, answered by experts

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

Regular inspections, loop flushing, and checking heat exchangers help extend system lifespan.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt.

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

Yes, including optimizing settings and suggesting upgrades if needed.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.
