Evan with RSP arrived at his prescribed time and was nothing short of kind and competent in his job. I had my free inspection and maintenance of my A/C-heat pump system purchased last year. RSP has made several service calls in recent years and each time I have found the personnel very personable and expert in their work skills. Thank you again!

Josh H.HVAC Maintenance
Our experience with RSP has been excellent on all counts. In addition to installing our replacement geothermal system, they made sure we got the guarantee benefits we were entitled to from the manufacturer. We enrolled in a maintenance plan with RSP and they have been superb in following through with the twice a year maintenance visits, always. As a result, our geothermal unit functions as it is supposed to. Couldn’t be happier with RSP!
Klay K.Cozy Club
