"I had AC Dave preform three jobs for me over the past few years. (1) New ducts a few years ago. (2) Installed a mini-split heat pump in master bedroom this year. (3) Then a few months later I had him remove my old Central AC and replace it with an 18 SEER heat pump and new coil, all the while leaving my old furnace in place as a back up. Dave and his guys did a great job on all three projects, completing each one in a day. Highly recommended."

"This was absolutely the best service I could have imagined. My vents went from filthy to spotlessly clean. I feel as if I can breath again. The value for the services provides was excellent. The technician, Elie, was fantastic. He was so service oriented and treated my wife and I like his own family. He worked with us on pricing so it was affordable and he gave us a ten year "club membership" for only $999.00 which gives us ten years of maintenance, twice a year for the next ten years to keep our heating and cooling systems updated and clean. I strongly recommend The Right Choice Heating and Air. They are fantastic. Thank you, Elie, for everything and keeping my family healthy! You're the bomb!"

"I can't possibly rate this company high enough. I am very pleased with the professionalism of the office staff and the professionalism and promptness of my service person, Chris. My preventive maintenance window was from 10:00 a.m. to 2:00 p.m. and Chris arrived at 10:00 a.m. He set about to check out my A/C system, added R22 (is it still called Freon?) coolant and cleaned my A/C unit. What was also refreshing is that I did not get a hard sell for any additional products, services or systems.  I am a new customer and will be a repeat customer. I asked if they also maintain and service heating units and received a yes answer. They will see me again for sure."

"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!"
This is the outdoor unit that offers 17 SEER Hyper efficiency and super quiet operation of 54db's compared to 80 plus on older units
notice the low profile, this is about 14 inch wide instead of the traditional 36 wide.

"We received about six estimates over the course of a year before choosing to work with Darrow and Mirsky Heating & Air Conditioning. His bid was considerably less than the others, but we chose Mirsky over the bigger companies because he is a real person who treated us like real people and more than just a sale. Darrow took the time to explain he recommended the system he installed and why we didn't need all the bells and whistles other companies were trying to force on us. The work took a full week with permits, when we'd been quoted 2-3 days (by everyone), but we didn't mind. The rule of the triangle says fast, cheap or good -- pick two. Darrow didn't charge us a penny more than the original estimate, despite the many surprises our old setup and the inspectors presented. It's only been a week or two, but our new system is shipshape and working great, just in time for the first heatwave of summer!"

"Ken came out an gave us an estimate. We knew immediately we would go with his service based on the quality of the brand Lennox and the price. The price was way less than the other 2 companies that we had called to give us a quote. Ken was a super nice guy and went the "extra mile" in every way. The crane on time and not noisy or an eye sore the morning of the installation. I definitely will be telling others about him.

"Lost our heat on a very cold late afternoon. Called 3 places. NRG was the only company that returned our call. Sent someone within an hour. Determined that our 28 year old unit needed to be replaced. Benjamin spent at least and hour on the phone to order the new unit and arranged to have it installed the next day, Thanks to all involved. Curtious, punctual, and professional."
