“Phillip was very honest and competent. He has a great personality, and arrived at the expected time.“

“Our HVAC system was serviced on the rescheduled date and time. They service tech was professional and gave use suggestions on ensuring we change the filters more often. Hopefully the office when sending jobs to technicians will stop putting last minute jobs on the schedule. Remember that people have to take a half day off of work when they have a scheduled appointment with you, so if you cancel on them for an Emergency job your customer has lost 1/2 days pay.“

“Payman was fast, responsive, gave me through details regarding every step of the process with reasonable price“

“I highly recommend Harts Heating and Cooling. Our A/C stopped working yesterday and as the high daytime temps were supposed to climb even higher this week, I really wanted good work done quickly. I chose Harts based on my community's Face Book Group recommendations page due the many recommendations. Jason exceeded my expectations. He arrived exactly when he said he would, was honest with all the possible causes, and allowed me to watch as he diagnosed the problem...explaining everything as he went. It didn't take long to find it was just a bad capacitor. He replaced it and then checked the refrigerant (which was a little low) so he added to spec. He took the time to check over everything and make sure things were working perfectly before leaving. He thoroughly explained all the work he did. He was very courteous and professional. If you need your A/C serviced, please give them a call and support our local small family businesses.“

“Proprietor and assistant acquiesced to satisfy my concern and anxiety about the detailing of townhouse before professional photographer is brought in to shoot pictures for multiple listing service. Technician laid drop cloths and placed plastic sheeting on vinyl siding to avoid residue landing on siding in the course of cleaning compressor. I found technician and assistant cordial, patient, ethical, conscientious and proficient. I am very satisfied with the cleaning, diagnostic, re-charging of freon gas and my overall experience with proprietor and assistant.“

“If you want competence and knowledge, call Alpha Aire. 24 degrees outside with no heat. Scott had it working in record time. He came highly recommended ~ I highly recommend him to you. I am ashamed to say I rarely take the time to write reviews. This man deserves 5+ stars!!!“

A small job because of his . honesty and integrity. He is to be commended by the company cause could see others just want to replace an older unit. Misplaced invoice otherwise would cite his name.
