"Drew from Legacy Plumbing came out IMMEDIATELY to our rescue because not only were all toilets and showers unusable because water would flood downstairs but we had a birthday get-together with family happening within the hour. Drew was very knowledgeable and quickly fixed our clog and we needed a replacement part for an obvious leak. Legacy Plumbing is super honest, and you don't feel like you're getting ripped off with unnecessary b.s.. This is the second time we've called and because of the great job he did on our last major issue with our old pipes, we called him again. The cleanliness, effeciency, and honesty of this company is why I felt compelled to rave about them and let people know in a review. Definitely my plumber and business to recommend from here on out."

"This is a small company. The wife answers the phone and makes appointments. She was very prompt in returning my call, friendly and professional. On the day of the appointment she texted me when he was on his way so I would know when to expect him. I never know what to expect when someone shows up at my door. One time I hired someone who just stood there staring at me when I opened the door and I had to ask if he was who I assumed he was. Not Mr. Utor. He was clean and professional, introduced himself and handed me his card. He immediately picked up on my bare feet and kicked his shoes off before he stepped inside, which always makes me and my light carpet happy. The repair went smoothly, he had a well equipped vehicle and didn't have to run to the store to get parts like some of the folks I've hired. He asked me about my air filter and took a look at it just to make sure. I'm pretty good about changing it but when he pulled it out it did indeed need to be replaced. I had one on hand and he installed it for me. I didn't shop price at all so it wouldn't be right for me to comment on that other than to say that I feel that what I paid was fair. Professional, punctual, friendly, efficient, a very pleasant experience. I don't hesitate to recommend HVAC-Utor."

"I've had Ron service our in-unit furnace for several years now and have always found him extremely conscientious and professional. He also replaced the furnace a couple of years back when it broke and that bigger job also went very well, with a cost that is in line with prices quoted on the Internet. Unlike some other contractors where the agreed time is just an indication of when you can expect to start waiting, Ron has often called on the day to ask if he can show up early, which is great because I'm not waiting around all day."

"My AC went out the last week of August. I called Supreme and they were out right away to make an assessment on my 20 year old unit. After educating me on what was wrong and how the old units are being phased out in California they gave me two options. Buy a new unit or replace the compressor. I opted to replace the compressor. The best part is they didn’t try to pressure me into buying a new unit even though I need one after 20 years. Instead they fixed the problem and followed up with me a couple of weeks later to see how things were going. They’re going to conduct maintenance to try and get as much use out of my unit until I’m ready to purchase an entire new one. I trust Supreme Climate Control and HIGHLY RECOMMEND them for all your HVAC, plumbing needs."

Install Boiler FAQs, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

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.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

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.
