"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."

"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."

"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

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.
