Air Plus Heating & Cooling installed my air conditioner to begin with and they did a very good job, Since then, I have asked them to come back twice to check it out. There have been no problems after they have left. Their pricing is normal. Their customer service is very good and responsive. The two times I have used them, the technicians showed up on time. They were also communicative and explained what they were doing. I will continue to use their service.
