What Customers Are Saying

"Very professional service. Installed A/C unit when my old AC died. He understood my situation and scheduled it promptly. Pricing was very reasonable. Highly recommended."

HK — Delaware, US

"Sunil arrived at the agreed upon time. He was very thorough in his search for the cause of my HVAC failure. He presented an estimate prior to performing the necessary repair. I highly recommend ProActive HVAC for HVAC service and repairs. Professional and reasonable."

Ronald Branch — Delaware, US

"I'd give five stars to ProActive HVAC Services. They were responsive, professional, and solved my problem quickly. The team was on time, explained everything clearly, and didn't upsell me on things I didn't need. Will use them again."
