We have used O'Connor for over 15 years. Every time I have called, they have been nice, professional, fast, and very good at diagnosing and fixing the problem.

They talk and listen to me, where other companies would only listen to my husband. I would give them a thousand stars if I could.

O'Connor Heating & Cooling was able to diagnose my problems with my old (30 year +) furnace immediately and recommended a new model that would be more efficient and give me a better peace of mind instead of putting a band aid on a failing system. It was replaced the following day quickly with extreme care in moving the new and old furnace across my kitchen floors. In addition, it is great to see a company that gives back to its community and those that are struggling. I consider every dollar I spent well worth it.

Pat replaced my furnace , AC unit for $1500 less than my quote. He also replaced my Hot Water Heater and I didn't have to wait. He was there first thing in the morning. Best in town!
