"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."

"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."

"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."

"Aaron Charles was our technician. He quickly diagnosed the condition as a faulty circuit board, called to have a co-worker bring a new one and got the furnace running like new. We were so impressed by how quickly he diagnosed the problem and corrected it. We will certainly use Mercurio's (and, hopefully, Aaron's) services 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

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.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.
