Palmer Gas & Oil Company
A/C Repair & HVAC Contractors in Londonderry
Average rating: 5 out of 5 starsJanuary 21, 2014
“We recently changed our carrier of home heating oil. It took us a while to get an appointment because we waited to long to call. In order for Palmer to put oil in the tank they had to inspect the tank and piping which I respect very much. We had them clean our furnance and was quite pleased, it was the best cleaning my furnace has had. The gentlemen explained to me the problem we were having with the furnace and what needed to be done. I would highly recommend this company to take care of your heating needs. I felt that they treated me honestly.”

What do HVAC contractors do? HVAC stands for heating, ventilation and air conditioning. An HVAC technician or contractor specializes in heating systems, air duct cleaning and repairs, insulation and air conditioning for your Londonderry, NH home and other homes.

When should you hire local HVAC companies?


Generally, Londonderry HVAC contractors or HVAC installers work with or run companies that repair or install heating systems and a/c services for homes.

Local air conditioning companies can help with a wide variety of air conditioning services, including both a/c installation and a/c repair. Air conditioning contractors, also known as a/c contractors, get extremely busy in the summer when temperatures are highest. For larger jobs, like installation, you might want to hire a/c installers during the off season like spring or fall. You should also try to do the same for heating services. Heating installers and heating contractors might be more available in the summer or fall for larger projects.

Ask HVAC contractors about these residential heating and cooling technologies:


  • Tankless hot-water pumps
  • Residential air cleaning devices
  • Ductless air circulation systems
  • A desiccant enhanced evaporative air conditioner system (for hot and humid climates)
  • Heat recovery systems (which cool the air and heat water with no extra energy use)

Find HVAC contractors, heating companies and air conditioning installers on Houzz. Look in the Professionals section of our website and search for New Hampshire HVAC contractors. Read reviews and see how an HVAC contractor might approach your Londonderry, NH home’s heating and cooling challenges.
