"Ranger Heating & Cooling was an outstandingly professional company, from the service technicians to the customer service. The installation went perfectly smooth and the techs were very meticulous in explaining how everything worked. The scheduling was very accommodating and the work went very quickly. I have already recommended them to a few of my friends."

"Received 4 quotes. Cummings was the least expensive that I used to bargain two others to. They matched but had install dates of 30 days. Cummings had their electricians and HVAC guys here in 8 days. Installation done in 4 hours. All had good customer service & tech skills."

"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."

"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."

"My husband & I requested two additional company bids and SOS Crawlspace was the most trustworthy & affordable.  Most companies send a Sales Person to provide a bid. Daniel was simply straight forward. I knew that we  could trust him; therefore, we went forward with SOS Crawl Space Insulation. The bid was to include crawl space removal of rodent infested insulation,  installation of new (R-19) insulation and the removal of construction materials in place since 1981.The workers were respectful and worked relentlessly; thus completed the job in two days. SOS Insulation is Affordable, professional and of excellent quality.

"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"

"The installation was completed in a single day. The workers were courteous and conscience. They did make a bit  of a mess of my attic insulation where the drain lines were routed, but they missed putting it back after putting in a pretty long day and that was a relatively easy for me to fix. The workers took the time to give a basic operating instructions for the thermostat.

After the installation there have been problems with the furnace. Phoenix has been very active in followup service calls in trying to get to the root of the problem, including bringing in manufacturer service personnel. The problem with the furnace is not related to installation by Phoenix. It seems clear there is some kind of defect in the furnace itself that has been difficult to locate and resolve. I appreciate the persistence of Nick in getting this resolved. There have been at least 10 visits by Phoenix personnel, mostly Nick, in working on this problem."

"They did a great job. I'm very happy with it. It came to a little bit more because they had to add some additional parts and change out the copper piping and that sort of a thing. It came to $1100 all total. They did a fine job, a really good job. The Angie's List special was for a Rheem water heater and they actually put in AO Smith water heater. So I talked to them about that. I said, "Well, I have a Rheem furnace, I would like to have a Rheem water heater." They had already put it in, I hadn't realized it. So I said, "You're supposed to put the Rheem in," and then the installer contacted the owner and they were able to give me a 10% discount or something like that. So they did give me an offset of about $110 or something like that. So that was good, they made it up for it. So I was satisfied with that arrangement. I assume that they're both of equal quality, but I don't know for sure. I settled for the reduction in the price."

Install Boiler questions, answered by experts

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

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

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.
