A-1 Heating and Cooling
A/C Repair & HVAC Contractors in Los Altos
Average rating: 5 out of 5 starsOctober 10, 2014
“I had a whole new furnace, ducts and air conditioning unit installed by A-1 The workers showed up when they said they would, were very respectful and cleaned up each day after the job. It took them only 3 days to do the full installation. There was a problem with one of the A/C parts and the owner sent someone right away and ordered a new part to get the problem fixed. I was not only impressed with the initial work, but you truly know a company is good with how they handle any problems that arise afterward. I would highly recommend A-1 to anyone looking for Hvac service!”

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 Los Altos, CA home and other homes.

When should you hire local HVAC companies?


Generally, Los Altos 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 California HVAC contractors. Read reviews and see how an HVAC contractor might approach your Los Altos, CA home’s heating and cooling challenges.
