"I hired northeast heating and cooling to replace my aging heating A/C system. This was a fairly large job, seeing it was a Multi floor house with two independent systems running both upstairs and the main floor. They also explained to me how adding a heat pump system to the house would help make heating my house less expensive during fall and spring. They replaced the entire upstairs duct work and reconfigured the entire house to run balanced and efficient. I couldn't be any happier with the work that was done in the house I would highly recommend them. Thank you Guy's for your hard work and dedication to get this system working amazing!"

"The representative came on time and listened carefully to my thoughts of a split ductless system. He suggested full house central air and showed me how it could be done, have ducts i stalled and cost less than a ductless system. His experience of over 20 years as a technician as well gave me a lot of confidence. He made a general proposal and came back in a few days for my convenience and I signed the contract. The duct crew finished in one day and were careful, explained things and left no mess. Then the ac was installed and tested in one day. Again polite, clearly communicated. Once the system started up late spring I am so glad I did this! No more noise from room ac, no shutting doors to keep one room cool. The humidity is normal and makes a huge positive difference. I highly recommend HARP. I switched my heating system to them as well after my experience with the AC i stall. Thank you HARP!"

"I had purchased a new digital thermostat and needed it installed. Ramon & his son installed it within an hour, replaced the outdated wiring to the gas furnace and made sure it was working. Overall, a great experience and a fair price."
