"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!

"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

I was in and out quick all fluids topped off, and potential problems brought to my attention, no sales pitch just good old fashioned honest people. We'll do business with them again. Highly Recommended

"During a heat wave we came home after being away for several days to an unresponsive AC unit. We called California Comfort first thing in the morning. Chris already had several repairs booked but he promised he would come before the day was out. He kept his promise, arrived at 6:30 pm and in 15 minutes had our AC unit up and running. To top it off when he found out we were new to SoCal and Riverside, he spent several minutes visiting and sharing his list of things to enjoy in the area. He was professional, knowledgeable, and friendly. We will definitely hire him again if and when the need arises."

"I can't edit previous review so posting new one: I am revising my previous review. After posting my first review, Danny in Customer Service at Home Comfort USA contacted me. Danny very patiently listened to my situation and frustration and told me he would look into it, but wouldn’t “leave me hanging” and would call back. He did call back and fast-tracked a HVAC technician, Jad, to come out, who was great and called in a higher-level technician two days later. Then the higher-level technician came out a couple of days after that and found we did need a leaking core replaced and said Danny would call me. Danny did call me and went above and beyond to get the part replaced under the manufacturer’s warranty. Two days after that, Home Comfort USA came out, replaced the core, tested our HVAC, and mitigated the labor. We are now VERY happy customers with Home Comfort USA and very grateful for Danny’s great customer service and intervention. I am writing this review on a day in the mid-90s with our HVAC system keeping us VERY comfortable. Thank you."

Install Boiler questions, answered by experts

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

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.
