"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"

"This is the second time we've called on Nick.  He answers his own service calls and was again able to come out the same day.  He arrived around his estimated time, was very thorough in his evaluation, and repaired the problems quickly in a no-nonsense manner. In my last service call to him, I had called several other providers, they were either unavailable or wanted to change out the entire system.  Nick was able to come out that same weekend day, offered a reasonable solution to my problem, and charged a very reasonable fee.  I knew whom to call this time for my HVAC problem.  I would definitely use Nick again in the future and would not hesitate to recommend him to family and friends.

"My parents were on a road trip in the middle of summer from TX to CA. Their A/C went out in the middle of the Mojave Desert. We called Precision Auto Works based on reviews. They fixed the car the next day and were extremely friendly. My parents were able to drive the car the next day, with air conditioning. The mechanics even helped to fix a few minor issues on my VW Jetta for free while we were waiting for my parent's car. Very friendly people, with exceptional knowledge about VWs.

"This could hardly have gone better.  Our washer decided to wet itself all over the place yesterday.  Called this AM, spoke to a friendly phone rep at E-appliance, and they sent out a repairman this afternoon.  Robert arrived within the specified window and quickly found the problem (fill sensor hose had detached on the inside).  Simple fix.  No BS, no trying to sell us repairs we didn't need.  He made some recommendations for how to prevent problems in the future, and even banged out a dent that had been in the front panel of the washer for years.  Should we ever need appliance repair again, it will be an easy call.  Thanks guys!

"Had a fantastic time working with Home Comfort USA. Their associate, Max, was prompt, very professional, and provided a personal touch to his service. He not only identified and repaired broken components of my home air conditioner but also advised outside factors affecting the unit along with advice to improve the unit's performance over its lifetime. The unit went from nonfunctional to running better than it has for years inside of an afternoon. Max went the extra mile to make sure that my family and I were taken care of and to provide a personalized experience. I definitely recommend working with Home Comfort USA."

"This is the second time we hired Zohar and his people to do remodeling and construction work for us. Last spring he remodeled our master and guest bathrooms and did a great job. This time, the job was much bigger. Zohar worked with us to architect a new kitchen. He is very creative and has seen just about every kind of kitchen, so he gave us a wonderful way to change our kitchen and to open it to our den. He did computer renderings to give us a visual view of his ideas. Sofia, who runs the office, was a wonderful help. She did all of the ordering and scheduling, and even took time on a Saturday to help us shop for counter top granite and back splash tile designs. We were new at it, and her help was greatly appreciated. We ended up with a beautiful new home and an amazing kitchen that my wife and I both love. Zohar is a man of his word, and takes his reputation seriously. Whenever there was an issue, during the long and complex construction period, he had it corrected promptly, and if it was an error on his part, he had it fixed at his own expense. As the job progressed, we did expand the scope in several areas. Zohar and Sofia worked with us and provided us with delta quotes for the extra work. We are thrilled with the end product and the quality of the work that he and his team did. My kudos to Zohar, Sofia, Ruven (foreman), and Nelson who did most of the drywall and painting. I highly recommend Best Builder's Group for any remodeling needs you might have."

Boiler Repair questions, answered by experts

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

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

Over time, a radiator can leak if turned off due to the built-up air pressure, which can cause water or coolant to leak. If your radiator leaks when it’s off, turn your whole system off and bleed the radiator, then turn it back on. If it’s still leaking, you might want to have an HVAC professional look at the issue.

Costs depend on issue severity, parts needed, and labor rates.

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.
