Get matched with top swamp cooler installers and replacers in Northridge, CA

"Great service. They quoted the job in advance based on my description of the job so the cost was as expected. The repair team, Dave and James, were punctual. They needed to take apart one unit to cap the valve. They were neat and quick to clean up of any the dust/dirt resulting from their work and disassembly of the unit. They were quite helpful and explained what would be required to fix or replace the heaters so we're informed on our options going forward. Their office admin/scheduler, Cherish, was excellent with communication and follow up."

"I own a laundry and needed two new swamp coolers. I called DNA and Andrew came out and from our first meeting was very professional. He was knowledgeable and able to answer all my questions which put me at ease. These guys did a bang up job. They were clean and made short work of removing my old units and installing of the new ones. I would highly recommend DNA for future work."

"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."

"Perfect. The service man, Mike Cohen, clearly knew what he was doing. He explained why the installed heater needed to be replaced; actually, I have some experience in these matters and had thought that the 10-year old heater needed to be replaced. Mr. Cohen had a replacement in his van and he replaced the old heater in about 1-1/2 hours: no muss, no fuss. I didn't dicker price because I had done some prior research. The price was competitive."

"Never having had air vents cleaned before I was a little unsure of how it actually worked and have nothing to compare this to.  I liked B very much, he was very helpful on the phone and while he provided the service.  He offered good suggestions and tips.  He seemed very professional, arrived when he said he would and finished an hour or so sooner than he thought he would.  He was responsive to questions before during and after and seemed to know what he was doing.  He did spend some time in his truck talking on the phone but I did not feel it impacted the service he provided.
The amount of dust raised by this activity drove me out of the house for over an hour.  We all developed bloody noses over the next few days although I ran the ventilating fan for well over two hours.  I am assuming that this is a normal part of having vents vacuumed out with a giant hose but I was not prepared for it!  I don't think that this was the fault of the service provider but it would have been nice to know before hand which is why I am posting this here.
The price was high but not out of the range of what other providers quoted to me and seems to me to be appropriate given other quotes.  I give $$ a B only because 3 days after I had the work done there was a deal for the same work for about $300.
