I would highly recommend GB heating. Good pricing and excellent installation. Service was above and beyond. If you need HVAC work in the Contra Costa area GB should be your choice.

We had two split units installed, the team was very professional in both the original and follow ups that we've managed through with them.

What an absolute joy and delight and relief to have Boris from GB Heating some to our rescue. After another company said our HVAC was not repairable and estimated between $20-30K for new system we were lucky to get a recommendation from a friend for Boris. He came out with positive attitude and reassurance (and no diagnostic fee!!) and within minutes found the problem. By next morning 7:30 am he already sourced the part and drove over to replace it. When that heater kicked in I was really happy. He also helped me with the best thermostat and checked for flow and monoxide in the vents. He saved us so much money and grief. An honest conscientious contractor is a rarity these days!! Don’t hesitate to call.

Boris from GB Heating was on time and knowledgeable in trouble shooting my gas wall furnace. Is great that he provided me with other options. I will definitely, call on them again when in need. Thanks again and appreciate your expertise.
