"Twice a year AC Dave comes to inspect our heating and cooling equipment. Their people always show up on time. They are well prepared because they know our house as we have retained them a little of ten years, since we acquired the house. There is always a good explanation at the end of what's up, like equipment that's still good, but obviously getting old, and may have to be updated or replaced. We're glad to have AC Dave as a reliable back-stop in case things might go awry, but so far so good."

"Albert was very polite, helpful and showed me some easier ways to maintain my system. He also offered suggestions on how to best utilize the 2 systems we have to best advantage. I was notified when he would arrive (along with a photo), then an update (as he was early), and work was completed in a timely, efficient manner. I would definitely use Southland Heating again!"

"Setting up the appointment was easy. They offered to come out the next day but I needed to wait until Friday, my day off. Mike showed up on time. Did a good professional job removing and installing a new 50 gallon water heater. Mike also tested my water pressure and noted it was too high. For an agreed upon small additional charge he replaced my pressure regulator and a shut off valve."

"The BEST phone call I have made this year for a service needed in my home was to Mirsky Heating and AIr. I called in the middle of a So. Cal heatwave because my thermostat had stopped working and I needed to replace it. How often does an AC company, in the middle of a heatwave, tell you they can come the same day? NEVER!! Except for Mirsky..Darrow told me that he would try to make it work..and he did...which I will be forever grateful!!! He checked in with me during the day to assure me that he was coming and not to leave work until he was more clear on the time he would be at my home. He showed up with another Mirsky employee named John..they were both super friendly and so helpful. Darrow found the problem and within 45 minutes, the thermostat was replaced and everything was up and running again. I can't say enough how grateful I am to Darrow and Mirsky Heating and Air...I am giving their contact info to all of my friends and will be calling them again for anything heating AC related."

"It was excellent. Chris Shay was excellent. He fully explained, was courteous and polite. He could see and understood why I had a previous bad experience with the install and cleaned up the mess that wasn't his that had previously left behind plus fixed other issues. He shared the pictures with his manager who also agreed that it was negative experience. He found that my account had fallen in the cracks and rectified the service that had been neglected. It was above and beyond my expectations. I look forward to him coming again to check up on the unit in 6 months. He also suggested and then installed an air cleaner which should help me with my health issues. All was accomplished today instead of being scheduled at a later date. I was very happy with him as he provided excellent service."

"They sent me a guy who was probably did plumbing for ten or fifteen years. Heating and Air conditioning, he did about three years. I had the heating and air conditioner for twenty years, and also bought this unit. The price is really high for an air conditioner. $12,500 if you want it down right. $4000 in the attic. It was $16500 investment. He didn't have what I wanted to hear. The gauges to calibrate anything. Nothing needs calibrating and told him the problem with the thermostat, and since he left he just turned it way down, I am trying to get eighty degrees, and keep it normal temperature. He is trying to get seventy eight, seventy five. Certainly its going to pump a little more colder. He didn't give us a reason why that thermostat isn't working right in the afternoon. He didn't have that answer, or the reason that you could adjust it. Can you adjust that? He had no idea of any adjustments of the thermostat. I didn't ask. I wanted to keep it all the same. I don't know, he didn't had the experience in heating and air, but he had the experience in plumbing. He didn't, and what he wanted for $85, its steep for me, when I just paid $16500, and for the attic ventilation system. I thought he would say $50 or $60. I paid him, and I went to Right Choice to do everything, complimentary. Something to help us out. I didn't ask them, but I would hope they would offer. He wasn't knowledgeable, and didn't know the answer. He wanted a $1000, it takes care of maintenance. Like he just came to the house. That is what he wanted to sell me. I gave him an soda pop, and wanted to see what he wanted to sell me.They sent an really knowledgeable installer. The parts are all knew. I would think they would have followed up, but nothing. Maybe that isn't a lot of money. I wrote a $12,250 check to them. Its a lot of money. I would want them to come out and make the air flows correct."
