Here’s a revised and enhanced version of the customer feedback, following all your requirements: I can't say enough good things about Harmony Heating & Cooling. When I woke up to a cold house in Westminster, I was really worried and started calling around for emergency AC and furnace repair. Clarence was the first technician who could come by within a couple of hours. He quickly checked everything and gave me a fair quote to fix the heating issue. Once I agreed, he left to grab the needed parts and was back soon after. By early afternoon, my furnace was working again and the house warmed up fast. The whole process was smooth and surprisingly quick. Clarence was very patient, explaining each step of the AC and furnace troubleshooting in a way that was easy to understand. He also shared helpful advice about upgrading to a smart thermostat and keeping our humidifier in good shape, which was new for us. On top of that, he even replaced our furnace filter at no extra cost! I really appreciate the excellent service and fast response. Five stars for sure!

We had Harmony Heating & Cooling repair and upgrade our heater in our newly renovated 1919 house in Westminster. After dealing with some really cold winter nights, we were eager to have our heating system working properly before another cold snap. The team took care of everything quickly and efficiently. Kai explained all our options for the repairs and was very thorough, keeping us updated from start to finish. Lucas was the technician on site who managed the heater installation and gave us helpful advice about where to place the new units for the best heat flow throughout our home. We had originally planned for fewer units, but Lucas recommended adding an extra one for better warmth and comfort, and he was absolutely right. He was able to get the extra unit delivered the same day, which really impressed us. Lucas and the crew did an amazing job working through thick old walls and tight ceiling spaces to make sure all the wiring was neatly hidden. The finished work looks great and blends in perfectly with the rest of the house. The scheduling manager, Clarence, also helped a lot by bringing in extra technicians when the project got bigger. Thanks to their teamwork, the repairs were finished just in time for the weekend, so our family stayed warm and cozy when the cold weather hit. We highly recommend Harmony Heating & Cooling for anyone needing heater repair or installation in Westminster. They gave us great advice, excellent service, and our home is now comfortable and warm. The new system is quiet and works perfectly.

A small but respected company

Very good

Amazing John is the best

John is a great man of integrity and honesty!
I give him 5 stars for outstanding service!

They use a third party scheduler and the right hand doesn’t communicate with the left hand. It seemed convenient at first but they showed up, the tech had incorrect notes on the job at hand, left, and then charged us for no services performed. Then it was very difficult to reschedule and would require additional payment.

I've known Charles professionally for years and he's the kind of person you want for HVAC. He's highly experienced, smart,honest, reliable, and fairly priced. I've referred him to any of my customers that need HVAC work and he's been incredible!

Charles was very prompt when our furnace started experiencing an issue. He suggested that we replace our system as it was the original from when the house was built. He was able to get it done the next day at a very reasonable price. I would highly recommend his services.
