The staff from Peterson Heating & Cooling helped install return air lines and maintenance for my entire HVAC system. They also performed work on my thermostat, as well. I have been with the company for around three years and in my opinion, the staff has always been professional and friendly. The pricing for their work is average. Since that average pricing comes with excellent quality and service, I would say that they are very competitive. I would definitely recommend them to other people and I will continue to use them for my HVAC system, as well as for any other issues that they might be able to provide service for.
