"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"

"I had 4 estimates.  The first vendor said he would be unable to test for leaks and said he would install new system and gave us a one line estimate.

 The second vendor said he could fill with freeon for $800 with no warranty or put in new system for $15k with no itemization,  He only attached a pressure gauge to outside line and was going to charge my very elderly Mom $105.  When I called owner and said that no diagnosis was made and this is ludicrous, he dropped the charge.

 The third vendor spent well over an hour explaining why his company is great and then said the charge would be approximately $9,500.

the fourth vendor was Mick Sinclair and what a completely different experience. I first called and spoke to Nick, his son.  I told him I did not know what to do.  Although both Nick and his Dad were booked solid he said he would get back to me.  Mick called and scheduled an appointment. He measured the pressure and tried to fix the valve. He then actually removed the outer shell of the condensor and noted that the motor was not working at all.  He tried to fix the motor and added a booster to no avail.  He refused to charge anything for the diagnostic and attempted repair - nothing!

Note, that not one of the other three vendors checked the motor.

Mick then said he would email a quote which he did in a very timely manner. His wife sent the email and I spoke to her and she was as nice as Mick and their son, Nick.

Mick spent 1-1/2 days performing the complete installation, including sealing asbestos and many other things.

There are literally no words to explain the excellent service we received from Mick. He is also very kind.

My 92 year old Mom and I are grateful for you.  You are truly a professional.

Thank you!

"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."

"The technician was very helpful in describing what the problems were (ON/OFF dial attachment broken off and clogged water level indicator). The fix for the clog was simple/cheap/quick but the broken dial required a new front panel which required an order and revisit. Still worth the cost of the fix and much cheaper than a new dryer.

Boiler Repair FAQs, answered by experts

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

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

Deciding whether to repair or replace your HVAC system largely depends on its age, the cost of repairs, and its overall performance. If the system is over a decade old and requires frequent or expensive repairs (e.g., totaling over $5,000), replacement is often the more cost-effective choice, especially if the warranty has expired. It is usually worth repairing a newer system, but if it is approaching the end of its typical 15- to 25-year lifespan, replacement might be a better long-term investment. Signs that you may need a replacement include increased humidity, higher energy bills, uneven heating or cooling, and excessive dust. Before deciding, ask your HVAC contractor to check if any parts are covered under warranty, which could save you money on repairs.

If your radiator turns on every time you turn on your hot water, your problem is likely your motorized three-port valve that’s attached to your boiler. When it malfunctions, the valve isn’t closing properly, so the water begins to flow to your radiator, thus kicking off the heat. To fix this, hire a boiler repair tech near you to replace your valve.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.
