"I’ve had the pleasure of working with Bill and Cool Air Technologies on several occasions and they never disappoint. They’ve done a HVAC replacement as well as an entirely new HVAC system install with impeccable results. They were professional and communicative; answering all my questions and working through any issues promptly. I will look nowhere else for my HVAC needs and highly recommend them to anyone considering their services."

"It went spectacularly well. Efficient, environmentally responsible equipment, and Steve and Martin are super competent installers. Alex Fish, who sold me the system, checked in daily while the work was going on, and was always available by phone or text if I had a question. Couldn't have asked for a better experience. Highly recommend them."

"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!"

"Brandon came out on a Sunday and looked over the job site for details needed to present an estimate. Within a day I had the estimate with 3 options from low to high, all of which were reasonable the only difference being what equipment I wanted to install. Option #1 and #2 were lower end brands that were less expensive but since the difference in price betwee Option #1 and Option #3 was about $1400, I went to Option #3 which was their top tier brand, Carrier that clearly is an industry leader and trusted brand for longevity. I was installing a SINGLE ductless to cool a standard bedroom size room with a 18,000 BTU unit. The job took a total of about 5 hours since they were mounting the unit in a second floor bedroom and they needed to run the power/refrigerant lines two stories down to the compressor mounted on the wall. Everyone from Office Staff Jim to installers were absolutely wonderful to deal with. You can trust this company."

"I needed my HVAC system urgently repaired, the technician arrived promptly to resolved the issue. They were professional and knowledgeable and gave me honest recommendations & also was very helpful. Highly recommend! Thank you!"

"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."

"SOUTHLAND HEATING AND AIR IS UNIQUE AS FAR AS I KNOW IN THAT AFTER A SERVICE CALL THEY SEND A "FEEDBACK EMAIL" IN WHICH YOU ARE ABLE TO GRADE THE SERVICE YOU JUST RECEIVED. THE FIRST "CHECK UP" BY ANOTHER EMPLOYEE DIDN'T GO SO WELL...BUT THANKS TO THE FEEDBACK EMAIL...JUSTIN READ IT AND RESPONDED TO MY CONCERNS QUICKLY. HE TOOK CARE OF THE PROBLEM WITH SPEED AND FAIRNESS. FIVE STARS!!!"

"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!"
