"I had to replace a water heater quickly. Gave me a competitive quote with a water heater with desirable specs within a day and scheduled me the day after. Technician was knowledgeable and efficiently performed the work. Water heater performs just fine. Cleaned up workspace and took a few mins to walk through water heater and maintenance after."

"I would highly recommend HPC Services! They responded quickly when we called for an estimate on a new heat pump. The gentlemen who were in our home installing the unit were professional and polite and very nice to our little dogs. Sergio stayed and answered all of our questions until late in the evening. They offered us a free duct cleaning and that was completed on Monday after the Friday install. Emmett worked quickly and professionally. He was so very nice and easy to talk to. I was most impressed with the fact that they offer a Veterans discount. If are looking for an amazing company for any HVAC work, I urge you to give them a call!! Karen Hamner"

"I spoke to Walt about doing an estimate to remove mold that resulted from a leak in our garage roof. Although we were slightly outside of their service area, Walt was agreeable to coming out as I was having difficulty finding and/or receiving a response from other companies with the proper mold removal certifications. Walt was able to fit us into the schedule quickly and was friendly and professional during his visit to perform the air testing and gather the necessary information to provide an estimate for the mold remediation. He contacted us promptly both by email and phone with the estimate and was able to schedule the job, all within a few days.
Kurt supervised the job and went above and beyond the call of duty. Prior to his arrival, we had not yet been able to confirm the source of the leak in the roof. Our roof is quite complex, having many different angles and being steeply pitched above the garage. A roofing company had attempted to locate the leak, but had been unsuccessful as well. Although this was not part of the service, Kurt (an experienced roofer) spent considerable time trying to find the source of the leak himself using our garden hose. He was able to isolate the area and when we called the roofers back, they concentrated on that area and were finally able to repair the roof. It's been a little over 6 months since all the repairs were completed and we've had no further water damage or mold growth. I gave AHS a rating of "N/A" for pricing as I cannot compare their pricing to other companies, who had an opportunity to provide additional estimates, but never responded to inquires. We highly recommend American Home Services.
