CoolWave came out the same morning I called. Our AC had completely stopped during a heatwave and they had it fixed in under 90 minutes. Friendly, professional, and very reasonably priced. Absolutely recommend!
Called about a furnace issue early in the morning and a tech arrived by 10am. They explained the problem clearly, gave me a fair quote, and fixed it same day. CoolWave will be my go-to HVAC company from now on!
Used CoolWave for our office HVAC maintenance contract. Their team is always on time, thorough, and professional. Since working with them our system runs more efficiently than ever. Excellent company, highly recommend!
