"Joyce Cooling and Heating installed a new high-efficiency Lennox furnace and air conditioner. The installation looks great and was professionally completed. The furnace is working fantastic and is so quiet we can't even hear it running. We are warm and comfortable all the time and the new high-efficiency design should save us money for many years to come. The technicians answered all of my numerous questions."

"Mike and his team were extremely professional and came up with a great solution for our home. We have baseboard and a combination of central air in the attic for the second floor and a minisplit for the 1st floor has been life changing for my wife who has bad allergies. Best investment we ever made."

"Steve and his team are real pros. Jason came out and talked us through the various install options, with a lot more thought and consultation than the other two contractors we talked to. In the end, the quote was higher, but we felt we were getting a better product, backed by a better company. Steve (the owner), Travis and Mike (installers) were pros too. Keeping us up to date, starting/completing the work on time, etc. The crew were super clean throughout the project. They even hooked up everything and reprogrammed my ecobee3 smart connected thermostats. Jason spent an hour on the phone with me about the unit and i know any of them would stop by if we needed more help. We were worried about what we heard about the noise factor with high velocity units and these guys take great care to design the lengths and add sound-dampening material to the last 3 feet of the vents. The whole system is super impressive. Couldn't recommend them highly enough."

"Through the several steps of getting this generator project done Palmer was on time and on task always. Their communication is outstanding from Michelle's initial visit and proposals through tank delivery by Corey and most centrally through all of Steve's installation work and coordination with inspectors, electricians and me. Two weeks later first power outage and everything worked like a charm. I just started with Palmer four months ago and added oil delivery and service to my generator work and I've been pleased with everything in the office and field. Very grateful."

"I called NRG Management and talked to Andrew around 9:30 AM, he was in my town by 11:00 AM. My heating system had seen the end of a 30 year run, and my family was without hot water. Andrew gave me a price for the job completed that beat any of the other companies quotes, I checked reviews and I felt comfortable to do business with Andrew and NRG. Andrew said he would be over by 7:00 PM to do the install, after he finished his workday. Andrew showed up with a new Buderus boiler, a Riello burner and 4 circulator pumps, a zone board and tiger loop with flex lines, all new plumbing with copper lines. This guy is Superman, after a full day's work he came to my home and did the install so my family would have heat and hot water, he finished at 4:30 AM, WOW. Andrew replaced my whole system the same day I called, he did a clean first rate job, and beat every other quote, my boiler room looks clean and professional. I highly recommend NRG Management and Andrew, the level of expertise on the equipment recommended and the install was second to none. I got my moneys worth, plus some = 1 HAPPY CUSTOMER. 5 Stars Thanks Andrew, The Harvey's"

"I found Comfort Air online and reached out to install central AC in my mother's condo. Patrick got back to me promptly, was very receptive in answering all of my mother's questions, and was able to start job within a couple of weeks from first call. The job took two days total, and my mother was impressed from start to finish! I highly recommend Comfort Air."
