I would suggest NOT using this company. I had been using them for the last 10 years as they installed my A/C. Something has change now and I will not ever use them again. I paid them $190 to come out and tell me what is wrong with my A/C. The outside fan motor stopped working. The problem is they gave me a quote for just replacing the motor, but you must also replace the fan blades and they did not tell me that information.

I only found that information after I had another company come out to replace the motor and fan. I asked for a $95 refund as they only told me half the information I was paying them to provide as part of the service call. I talked to the service manager (Melanie) and she said no refund would be given as they did come out and I would only been given all the information if I used them to do the work.

I feel like they are given out quotes for a lower price to get the work and then hitting people with more changes after the fact. The quote from them was $925 to replace just the motor but just fan blade part was $260. So the quote should have been $1,185 or more. I guess they did not want to give me the higher price up front.

The smoothest process I can recall in replacing a major home system. Patrick, Levi and Anthony were wonderful and installed an upgraded Carrier heat pump with the allergy and asthma features I need. Keep up with annual service and an emergency is unlikely until your unit gets old, but they will respond. I'm a repeat customer of many years with Bob Heinmiller. There is no reason to go anywhere else.

I give Patrick and his team my highest recommendation - they recently relocated our A/C unit to accommodate a backyard pool project. Patrick and his team are super pleasant and easy to work with. They completed the job in a timely manner and kept me updated from start to finish. They're pricing is very competitive and the final project cost was on par with their original quote.

I can't say enough good words about Bob Heinmiller Air conditioning. From the moment the units were installed until having one replaced because a faulty mechanism. The professionalism and one on one interaction with the service manager makes it easy to recommend this company to anyone seeking a good a/c company. Service: A/C system repair
