"Ranger did a great job. The estimators were friendly and thorough, the installers and team we encountered were all respectful and hard working. There was a problem with the electronics in the thermostat from the factory, they worked late and had to bring a new thermostat the next day, but the new one works perfectly. We will hire again for any other HVAC needs. We chose a higher quality AC unit and are glad we went with a quieter model, the unit is so quiet in the backyard."

"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."

"I had an excellent experience with Jose Plumbing Excellence Northwest. They first helped me fix a leak, and later replaced my water heater when it went out. Both times, they were able to schedule me right away, which I really appreciated. The team was professional, efficient, and made sure everything was done correctly. Their customer service was great from start to finish, and they made the whole process smooth and stress-free. I highly recommend them for any plumbing needs!"

"Service was excellent/price competitive. Furnace went out during week of snow storm. Bob & Allen made it to my house and were able to install my furnace. Even though it was very cold and miserable (with them getting stuck in the snow and having to dig out just to make it in and out of my driveway) they remained professional and upbeat. You will see by the attached photos the huge effort these two men had taken to provide heat to a customer who had none. Thank you for going above and beyond. Will continue to be an annual service customer."

"This company made the process of getting a heat pump (new installation) very easy for us. They were fast on coming out for the initial bid (Brandon is great!) and they were super fast on the installation. Lorin and his crew were delightful and did an excellent job! There price for everything was way better than any other quote we received and they were very conscientious about how they made everything look. We are very satisfied with every aspect of this project and highly recommend them! I would definitely hire them again!"

"G&S Heating is the best of the best! They just replaced our 1995 Lennox furnace that they installed with a 2020 Lennox furnace. The crew was phenomenal in craftsmanship and attitude. Our furnace is in the tight crawl space under our home which is a pain in the @#*! They really worked well together and it was so cool to learn that one of the guy's father had installed our furnace back in 1995 and he is still with G&S! Their entire operation focuses on customer service and satisfaction from the phone contacts to the sales reps to the job planners and finally the installers! I am giving G&S my highest recommendation and will have them install our new Kohler 20KW whole house generator soon. Thank you G&S... Tom H"

"We'd used them four years ago to replace our windows. They were about 40% the cost of Renewal By Andersen for the same Andersen windows, were professional and courteous throughout the process, and we haven't had a single problem since. So when we wanted to put in a heat pump system for efficient heating and cooling they were high on our list. We got four bids, and once again they were the least expensive, in this case by a 30% margin. They explained our options well, came up with some creative solutions (we're an old house with old vent-work which they bypassed for the ductless pumps but used for a top quality air filter), and did the job quickly and efficiently. They've checked back a couple of times since to make sure everything is ok, which it is, and it's been really nice to heat our bedroom on some cold nights and cool my western facing home office on some sunny afternoons). When the permit inspector asked before they came over who our installer is and I told them, they said "They do really good work." Definitely recommend them to others and in fact already have."

Install Boiler FAQs, answered by experts

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

Propane is more cost-efficient than natural gas on a per-unit basis because it produces twice as much heat energy as an equivalent amount of natural gas. But propane is not ideal if you already have a gas line installed. The best choice for your home depends on the efficiency of your appliances and the amount of installation required of your fuel choice.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

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.

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.
