"I purchased a new Navien NPE-240A2 Tankless Water Heater and had it installed. I'm loving the new water heater. It replaces an old Noritz tankless that died just before this installation. The on-site estimate was what sold me. Ken went through all the details and answered a lot of questions from me. Zachary came out with Austin and performed the installation just like I discussed with Ken. Zachary kept me in the loop throughout the installation to ensure I was in agreement with how it was going. Zachary always had my interest at heart and ensured no corners were cut. The installation is much cleaner, and more correct than the previous tankless company did. Zachary even listened to my concern about the astectics of the exterior exhaust and quickly found an easier and cleaner looking way to address my concern. He also removed an old recirculation pump and replaced a new main house shutoff valve. The entire area was treated respectfully and left cleaner than they found it."

"I'd been wanting to get of our old electric baseboard heaters for a long time, and replace it with something more efficient, and Mark helped my understand the differences between a ductless mini-split system and a ducted heatpump system. Even in our small house, the ducted system was the way to go. Mark and his installers were professional and efficient, and answered all my questions. When the thermostat was acting a little odd, he sent a technician over to calibrate it, free of charge. There was a small issue where I initially got the wrong specs for the electrical, and as a result I had the electrician install unnecessary circuits, but Marc reimbursed me for the cost."

"The entire process went very smooth. From the initial call to final install, everyone was pleasant to work with. The Comfort Advisor, Scott, put my mind at ease with all my questions and concerns. I got the quote shortly after the assessment, accepted and was scheduled for install very quickly after. The install team was very communicative during the process. They all came in and worked together to get the job done in a short amount of time and left the area looking better than when they arrived. Everything has been working great and I couldn't be happier with my heat pump. I would not hesitate to recommend them to anyone I know."

"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...…"

Install Boiler questions, answered by experts

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

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.
