Josh was polite and straight-forward.Last year I had a problem with my A/C losing its gas charge, Oppo Heating & Cooling, Inc serviced it and added 3pounds of gas and stopped the leakage .Gave them a chance and the experience was great.Too many of these companies are not straight forward, but Oppo Heating & Cooling, Inc was honest.I recommend them fully.

We called the day before for an appointment and they called 45 minutes after their appointment was suppose to be starting to let us know they couldn’t make it. There is snow but as a healthcare provider, we still have jobs to do and people depend on us. We don’t have heat right now and they were a huge disappointment. I would not recommend since they are not dependable when they are needed. They should explain they are only 24 hours if it fits their schedule.

I had a great experience with Josh at Oppo Heating & Cooling, Inc.. He was timely, friendly, professional, knowledgeable, and explained everything he was doing while he did it. Price was more than fair and I will call again if needed!
