The folks at Bay Heating Service are polite, prompt, and great to deal with. They replaced my furnace about 10 years ago, and this past spring they installed a new central air system. I was impressed with the fact that they’re super clean when they do a job for you. For example, they protected my flooring by covering it with rubber mats. The service is absolutely wonderful!
