Al was professional and very courteous to my wife and myself. He took the time to explain what was wrong with our air-conditioner. He explained that a new a-coil was needed. Thank you to hiring such a great tech. This is what good business is all about. Adam please pass this review on to Al. Services: Cleaning, A/C system maintenance

Been using them for a few years now, they put in a new furnace and AC. Everything was quick and easy with no pressure. Everyone I've encountered has been professional, courteous and kind - from the receptionists in the office to the techs that come out. The prices are reasonable and techs are very knowledgeable and friendly. It doesn't feel like it's "just a job" with them, they take pride in their work and seem to really enjoy what they do. Highly recommend this business for your heating and cooling needs!

We had a great experience using Official Heating and Cooling. Very professional from the beginning to finish. Had a new furnace and air-conditioner installed. Alfredo and his team showed up on time, finished up by 3, left our home without a trace of debri, and took the time to familiarize me with how to maintain our new units. We also had our ductwork cleaned. Same experience. Showed up exactly when we were told he would, cleaned our ducts and was done by noon.
We did our research before we chose Official. We read reviews, noted that all technicians were NATE certified, insured, and licensed, had a BBB A+ rating. This was a huge investment for our family, we needed a company we could trust. We are very happy with the service Official provided.

I had a great experience today with Official. Our furnace gave out in the middle of the night and it wasn't until this morning at 8:00am when the temp had already dropped to 52 degrees that we noticed it. We gave Official a call and they had a servicemen out by 12:30. He was knowledgeable, kind and helped us with the issue right away. Only an hour later we had new parts ordered, picked up and installed. Can't thank them enough for quick service. We will be using them again in the future for our vents and ducts to be cleaned.
