Featured Reviews for A/C Repair & HVAC Contractors in Walnut Creek

B Green Service
A/C Repair & HVAC Contractors in Walnut Creek
Average rating: 5 out of 5 starsDecember 5, 2017
“Great company! After confirming with PG&E that the awful smell from our vent was not a gas leak, we called B Green Service late in the evening and got a call back first thing in the morning. Dan was helpful, a good communicator, and arranged for a team to come out immediately. The workers were courteous, prompt, also great communicators, and immediately figured out the situation. They were upfront with the potential costs, and their recommendations, solved the problem (a dead rat), and also disinfected the vents for us. We are very pleased all around, and are happy to recommend them to all our friends and family!”

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 Walnut Creek, CA home and other homes.

When should you hire local HVAC companies?


Generally, Walnut Creek 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 Walnut Creek, CA home’s heating and cooling challenges.
