"They guy who did the inspection was very professional. When I had the work done, they were here for two hours and seemed efficient. I can see the vents that they installed in the exterior of the roof, but until someone gets up there to look at it I wouldn't know how the work turned out."

"I couldn't have asked for a better service person. Alex came for consultation on my electric hot water heater replacement. He quickly diagnosed and fixed the problem and told me my water heater is fine. He is a true professional. He was very kind, pleasant and courteous, and gave me useful information about water heaters and installation issues in general. When my 10-year-old water heater quits for good, I know where to go. Thank you for the great work!"

"I am very pleased with Sunset Heating and Cooling as a new customer. Isai Ubaldo arrived to conduct a thorough inspection of my home's HVAC unit. Isai demonstrated himself to be an expert in the field, explaining why the heating element was failing. Additionally, he gave me options for the cost of repair vs. replacement. I received real numbers, objective data, a complete overview of the entire maintenance program, and transparent information on the hiring practices of Sunset Heating (competency requirements/security checks). Very impressed with both Isai and the overall integrity of the company. Company integrity, both within the company and how the company is represented by team members, is crucial to business success and continuity. Thank you, Isai."

"I live in Tucson Arizona andI just want to say that I haven’t had any work done by J&M, but if I lived in the Oregon or Washington area I wouldn’t consider anybody else. I’m trying to get an underground gas line installed. I searched all over the web and found J&M, and after reading everything about Jeremiah and his company I emailed him a question. He called me back and thoroughly explained all my different options and was extremely polite professional and a pleasure to talk to. He even referred some companies in the Tucson area for me to contact. In this day and age it’s a pleasure to find a company and somebody like Jeremiah who has that kind of integrity."

"Specialty Heating & Cooling was the only company of 4 we talked with to propose an ideal plan for running new HVAC power & cooling lines through our attic -- optimally locating and minimizing visual impact both inside and outside the house. They even added additional lines we requested for future additions to other rooms as we or future homeowners desire. Installation was quick and professional, with good communication throughout. All done at same or lower price than competitors. Our kitchen and adjoining DR & LR (and the whole house) have never been so comfortable on 90 degree days. Winter heat is way more even and comfy too. All from one unit! We previously used only a Yotul gas stove and rarely-used electric ceiling heat for 3000 sq. ft. in winter, and a giant oak tree to shade us in summer. Denise T."

Install Boiler questions, answered by experts

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

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.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

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.
