Best boiler repair pros near Paramount, CA

"Excellent heating repair service! The technician diagnosed the issue quickly and restored warmth to our home in no time. Very friendly and professional throughout the process. Highly recommend them for fast, dependable heating solutions."

"This was by far the best experience I've had when it involves repairs. My heater had been broken for a year. Because I'm on a fixed income, I couldn't afford to replace it. Quotes from others all recommended replacement. HD Mechanical gave me an estimate for repair and it was fixed right away, an at a fair price. Brandon and Tim are the best and are professional and dedicated to getting the job done without trying to upsell to unnecessary replacement. It works fantastic. They also happened to fix my ac as well, with no cost to me. If you are a woman alone, hire this company. They're honest and fair, and provide great service"

"On Monday, May 12, our A/C wouldn't turn on and was scrambling around trying to find someone to fix our A/C ASAP since this weeks forecast weather is going to be hot.  I called a few repair companies and the closest appointment is on Wednesday.  Left a message with this company and Nick called me back.  Nick came over to fix our A/C on the same day.  He was prompt, friendly, professional and got our A/C working.  I highly recommend this company and I will use their services again.

"The water heater stopped working on a Sunday afternoon. They were able to get a technician to my house in about 45 minutes. Mario quickly evaluated the problem and fixed it. Very thorough and professional!"

"Everything from my first telephone call to the final handshake was perfect. Darrow Mirsky arrived at my house the morning after the evening when I called. He was at all times courteous, prompt, and very clear about all my options. My options were to replace the old condenser which had failed or to install an entirely new unit. I chose the latter based the 30+ age of the existing unit, getting a 10 year warranty, and better efficiency to mitigate the price difference. Darrow put no pressure on me at all in making my choice. Emilio, who did the actual installation, was also terrific. Both Darrow and Emilio answered all my questions patiently and clearly. Emilio worked diligently such that the entire job was finished within two days after I called. I very highly recommend Mirsky Heating and Air Conditioning. First rate."

"Very well, technicians were very thorough, and explained repairs in detail.

"This company was the second i had out to look at repairing our tankless hot water heater. For over a week the hot water would turn off randomly.  Baltica was my second opinion  for the repairs and i felt really lucky to have found them on Angie's list. The first company told me i needed to replace the entire 5 year old unit for $2200.00. Baltica answered all my questions before coming out,  Marius assessed the condition once  he came out,  the unit was flushed and clean out valves were installed he was very professional.  How nice to work with a company that stands behind their service.

"Very prompt, professional, and fast. Diagnosed quickly, fixed quickly, and didn't leave a mess behind for me. Super friendly technician, noticed things and struck conversation just to show a personal, polite side. Would definitely recommend."

"After many roofing estimates that were incredibly high and came with either no financing or high interest financing, I stumbled upon Zen Builders. Simon was attentive, knowledgeable, and on top of his game. My roof was completed in three days, it's beautiful, and there were NO LEAKS when the rains came a few days later. The workers were professional, considerate, and the clean up was amazing. No trace of having construction in my yard. Because I was so happy with the work, I mentioned to Simon that I would love to have him come back and do a few more projects. I ended up with an even better financing option (both loans are well-within my budget) and a GORGEOUS new patio cover complete with a surprise ceiling fan in the middle! The patio is now white, and they painted the trim of my house to match. They also fixed my heating/AC ducts, insulated my attic, and for free, added plywood, so I can actually store items up there. I have never had an issue getting ahold of Simon or his sister, Kineret (Kerry). When there was an adjustment needed to the air ducts, the workers came out quickly (amid the COVID-19 quarantine) and simply fixed it! I couldn't ask for more! All work took less than a month to complete and I never felt pressured, ignored, or bamboozled. I have recommended Zen Builders to many of my friends. I hope they recover from the imposed quarantine to continue to provide excellent service."

"Excellent customer service and fast! I highly recommend them, if you need a new system or maintenance this is the company to call!!!!"
