"Brandon came out on a Sunday and looked over the job site for details needed to present an estimate. Within a day I had the estimate with 3 options from low to high, all of which were reasonable the only difference being what equipment I wanted to install. Option #1 and #2 were lower end brands that were less expensive but since the difference in price betwee Option #1 and Option #3 was about $1400, I went to Option #3 which was their top tier brand, Carrier that clearly is an industry leader and trusted brand for longevity. I was installing a SINGLE ductless to cool a standard bedroom size room with a 18,000 BTU unit. The job took a total of about 5 hours since they were mounting the unit in a second floor bedroom and they needed to run the power/refrigerant lines two stories down to the compressor mounted on the wall. Everyone from Office Staff Jim to installers were absolutely wonderful to deal with. You can trust this company."

"I am writing this review after a year because I wanted to test it out and provide an honest review. We replaced our AC unit with a new one with the help of NathanD. He was extremely professional and offered us the best price compared to all the other companies we considered. The installation process only took half a day, and they also installed a Google Nest for us. Additionally, they assisted in fixing our broken circuit board in the garage. Overall, the workmanship was excellent, and NathanD answered all of our questions. He even followed up with us after 2 months to check on our satisfaction. We initially found him through Angie's List."

"Nick Sinclair handled my project. He was really great. I had no clue that you had to have a permit in order to install a furnace or water heater. An inspector came out and told me that I would need a permit. They had to drive from Orange County to Riverside County in order to get the permits. These guys stopped everything, drove out there and took care of all the permits. They installed everything promptly and it was just the perfect job. Their prices are fantastic."

"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."

"We received about six estimates over the course of a year before choosing to work with Darrow and Mirsky Heating & Air Conditioning. His bid was considerably less than the others, but we chose Mirsky over the bigger companies because he is a real person who treated us like real people and more than just a sale. Darrow took the time to explain he recommended the system he installed and why we didn't need all the bells and whistles other companies were trying to force on us. The work took a full week with permits, when we'd been quoted 2-3 days (by everyone), but we didn't mind. The rule of the triangle says fast, cheap or good -- pick two. Darrow didn't charge us a penny more than the original estimate, despite the many surprises our old setup and the inspectors presented. It's only been a week or two, but our new system is shipshape and working great, just in time for the first heatwave of summer!"

"The problem was resolved by cleaning a sensor for which they only charged me half hour labor. He also wrote me a letter when we filed with the licensing board. He suggested that I get a different type of connection from the gas. I wanted to give him some more business because he only charged me 50 bucks. So, I had him come out and do that. He showed up on time and didn?t jerk me around. He didn?t give me an inflated estimate and he did what he said he would do. I am pleased with him."

"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

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. 

Costs range from $3,000 to $7,500, depending on system size and efficiency.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.
