"I first contacted Valley to get a quote on how much it would cost to get air conditioning installed. I live in an older town home that is approximately 1100 sq. ft. They sent someone out to take a look and see what was involved. He was very professional and explained what was involved including getting permits from the city. He quoted the amount and provided me with an invoice. I contacted them 3 months later to say I was ready for the install. The installation turned out to be quite challenging due to the way my home is constructed, but Valley made it work. The service person had to stay a few hours longer but I wasn't charged anything extra for it. They stuck with the amount of the estimate that was quoted. It's only been a couple of months since the install, but I have to say my only complaint at this point is how cold it gets when I turn on the air. But that's a nice problem to have. :)"

"I'm super glad I took advantage of this offer. James Hayden came out to my house and did a thorough inspection on my furnace that was probably from 1970. He had the tools and equipment to be thorough, and I found him super knowledgeable and friendly. James found very high CO levels in my exhaust and recommended that I not run the system until we got this resolved. For the safety of my family, I'm so glad he had the tool to measure CO levels, and that he identified the safety problem."

"This guy is a real pro! The original installer came out and gave up on the problem, and I never heard from them again. Duke came out, and diagnosed the issue in an hour. He even submitted the request for a part under warranty, received it, and came back to install it 2 days later. The cost was very reasonable. Thanks Duke!"

"These people were real pros. My heating boiler failed - it was only 48 years old!!! They installed a completely new system and lent my tenants heaters while the boiler was on order. They were very good at getting back to me and excellent at explaining the work they would be doing."

"Had a wonderful experience when Joaquin, Ben and Anthony of ABC Cooling, Heating & Plumbing came out to install my mini-split heat pump unit this week. Professional, respectful, skilled at their craft, and with attention to detail. They communicated clearly, kept mess to a minimum, and cleaned up thoroughly after themselves. Highly recommended!"

Install Boiler questions, answered by experts

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.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

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.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.
