"Great professional service. Showed up next day to fix my AC. They found and repaired the previous work done by another company. If you want the work done correctly and you want to pay fair pricing, call them. The previous company I used were not honest and sold me fixes I did not need and did not repair the things that needed to be repaired. I think they did this so they could continue to come out and charge me for things like adding freon to my AC but never repairing the leak which I eventually found myself. The leak was in an outside line, highly visible (once I knew what to look for). I called AC Dave and they fixed it right away and my AC has never worked better."

"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"

"Darrow and his team did an excellent job! During a 100+ degree heat wave, our 2nd floor A/C failed. My prior A/C man had recently retired and I was scrambling.... reviewed Angie's List and made several calls. In several cases, I found myself as caller #10 in the queue. Darrow took the call personally, however, and was able to see us late that day. As a businessman I'm used to moving slowly, assessing, considering alternatives, etc. On this occasion there was no time, had to go with my gut. Mirsky Heat & Air really came through. They spent several hours (6-9pm) testing different options but ultimately found the compressor required replacement. They were able to return a day later and install the replacement. Their price was fair, Victor (his associate) was extremely knowledgeable, their work was first rate... and their response during a crisis was a life-saver! We highly recommend Darrow and his team... they're the Real Deal!!"

"Joe was punctual, polite, and very helpful. He took a little while to diagnose the problem with the heating unit, but once he figured it out he had the part ready and the installation underway (he first told us what the part would cost and asked permission to go ahead with the repair- which I appreciated). He tested the unit when he was done to make sure it was the right fix, which it was. Then we asked if he could also look at the air conditioning unit while he was here, since it stopped working at the end of last summer. He took some more time to fix that one, which was even harder to diagnose. But, he kept testing until he found the problem, and in the end we had 2 operable units that will save us from another service call in the busy summer season. It was worth the money.

"The dealer wanted $950. Precision did it for $600, as quoted using original mfg. parts. Owner asked what else was wrong with the car and I told him that Toyota wanted to clean the injectors....well the owner here said that cleaning injectors was the biggest scam in the auto industry and went on for five minutes as to why.   When I picked it up, he said my steering was making a small knock and that was the rack and pinion and I could wait until it got worse before having it repaired.  This is a small shop but has integrity.... a rare commodity."

"Cal Climate was prompt in response for scheduling my appointment and they followed up with an email reminder/confirmation. My condo heater had not been heating the bedrooms well during very cold nights. Mike came out to check on my heater, he was extremely professional and knowledgeable. It happened that my system was working fine the day he arrived (it was a warm day) and he was unable to identify the problem after performing a number of tests both inside and with the unit on my roof. Mike suggested that if it happens again, he will come out promptly to take another look. I highly recommend Cal Climate!"

Boiler Repair questions, answered by experts

Probably not. Moving a boiler to a new location is a very different prospect from replacing it in the same spot, and significantly more expensive. Plus, boilers are typically carefully positioned in proximity to pipes and radiators when installed. Homeowners may want to move boilers to free up space, prevent freezing problems that have happened in winter, or solve a noise issue—but it’s a much more costly proposition.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

Regular inspections, cleaning, and checking of exhaust systems maintain safe operation, ensuring efficiency.

Leaks, pressure loss, air in the system, burner failures, and thermostat malfunctions are common problems that require professional repair.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.
