Mark is great, he responds quickly pricing is very fair & he does what he says, I had a new ac/heat system installed in my daughters condo in mission valley & Mark has great pricing, was there when he said he would be, did exactally what he said he would do & answered any questions I had along the way, as for the work, it came out great ac is ice cold, him & his crew are profesional & clean up when there done, I would highly recommend you call him if your looking for a new ac/ heating system or just have an issue with your existing system.

Mark was spot on in getting the job done on time and the final bill was actually less than the quoted price. I was in shock. I have never seen this happen from any AC company in my life. I would highly recommend Mark's Heating and Air to anyone

I can not say enough great things about Mark! He is so sweet and so quick! I recommend to EVERYBODY! I will be telling everyone about this guy hes amazing! Thank you thank you thank you so much for everything!

Spoke to Mark about installing ductless units in our 1950's home. He came out that same day, gave us honest advice and a great price! I was not expecting that. His guys came in and installed the units with great class! They were very respectful and really worked well together. I honestly couldn't be happier. Definitely saved their phone # in my contacts.

Starter capacitor on the heat exchanger went out during our 100°+ heatwave. I called 4 companies with 3 day to a week response times. Called Mark and he came out the same day. 20 minute fix. And he found a duct problem in the house and fixed that too. Very reasonable prices. Nice clean service vehicle. Mark was very pleasent. He's in my contacts now.
