"Mark and his guys helped us install a new AC last summer. They arrived on time and did a great job! So when I was looking for someone to do the maintenance of our furnace, I called them. Todd went above and beyond my expectations. He finished the job and even helped fix my hinge. Both Mark and Todd strike me as very genuine people. And I would definitely hire them again!"

"Jane's replaced my 20-year old Munchkin boiler with a super efficient, modern Rinnai. Everyone was a joy to deal with. Service was excellent. Darian, who scheduled and arranged the replacement, and Greg and Oscar (who did the work) were fantastic. Excellent service, especially since I live on Lopez Island, which is not easy to get to. Competent, good-natured, hard-working, nice folks."

"Lifetime Heating and Air Conditioning is the best around! Great competitive pricing. Professional, clean and extremely knowledgeable crew who are able to adapt to issues while keeping the homeowner informed. Our house was built in 1969, with a converted garage turned living room, and a handyman's addition off the master... Not a pretty sight in the attic....These guys didn't skip a beat. the way they adapt and overcome makes me know we chose the right contractor.... The moment I reached out to Dwight, I knew we would be treated like family. They did not disappoint. Our home was not an "easy job". Not to mention, not letting our 5 rescue cats out, to loving our rescue pup like their own...The install crew left our home cleaner each end of shift than I keep my own house. This company will be around for years to come. I cant wait to tell everyone who needs HVAC work, that Lifetime Heating and Air will be your first and last call...…"

"They came out and installed our new furnace and they did a good job. They advised us on the different types of furnaces to purchase and we appreciated knowing the pro's and con's to the different types.  We would definitely recommend them. They are nice guys to deal with and also very professional."

"4 stars because at first they quoted me one price for the furnace and then installed something different. He installed a 3 ton when he quoted me for a 4 ton. They didn't change the estimated price, so I told them to take it out and install a new 4 ton. Other than that it was a good nice perfect gentleman."

Install Boiler FAQs, answered by experts

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

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.

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.

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.
