"Perfect. They arrived on time, were polite and did their job as expected. The sales professional (Jim) was honest and forthright and did not try to sell me any additional products! I know people who have used Greenwood before, sometimes for more than one service, and they wouldn't use anyone else! I feel the same! I have already referred them to my neighbor and my brother, who just had a new furnace installed two days ago and was happy with technicians (as I was also) and the company also...Highly recommend them!!"

"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."

"Darrick came out when no one else could and went through my Furnace and Air conditioner. The furnace was fine but found a potential problem with the air conditioner and went out of his way to get the part and fix it right away. I am now looking at having them install a new Thermostat for me. I Highly recommend them and would use them for all my needs."

"Blue Flame did a great job installing a new furnace in a very difficult location in our home. Even with challenges the service person was thorough, meticulous, and did the job right. Since the install we've continued to work with Blue Flame on the regular maintenance and would absolutely work with them again."

"The installation of our new heat pump was to take two days, and I assumed would be done during normal business hours (8:00AM - 5:00PM). I expected a smooth process and a properly working system at the end of the 2nd day. The experience was not even close to my expectations. Day 1: Old air handler, heat exchanger, compressor pad and compressor were removed; new air handler, heat exchanger, and compressor pad were installed. As expected, the new compressor was placed on the pad, but not connected to inside unit. I observed one of the four-man crew scraping gravel from my neighbor's driveway to put under the compressor pad. When I told him that my neighbor probably would not like that, he said, "It will be OK. I'll smooth out the places I took it from." He couldn't have given a more wrong answer! Late in the afternoon, the electrician (an Overlake subcontractor) arrived to hookup power to the new system, and all four from the installation crew left. (I think at least one of the crew should have stayed until the electrician was finished to verify that the system was working. And maybe to explain to me how to operate the new thermostat!) About 90 minutes later, the electrician was finished, but the system would not turn on. It was not his job to troubleshoot system problems, but with the guidance of someone over the phone, he managed to find two wires that had not been connected by the Overlake crew. He connected the wires, but that made no difference. I was supposed to have backup electric heat working at the end of Day 1. This was important because it was December and the temps were down to 32 degrees at night. After 2 hours of trying to get the system to produce heat, the electrician left at 7:00PM, and an Overlake tech arrived at 8:30PM. At 10:00PM, the tech determined that a circuit board in the air handler was defective, and a new one would have to be obtained and installed in the morning. I managed to get by with two 1500-watt space heaters by closing off most of the rooms. Day 2: Before the techs arrived, I noticed that the compressor pad, with compressor installed on it, was significantly out-of-level. The techs arrived at 10:30AM, and I asked them to purchase a bag of gravel to replace what had been taken from my neighbor’s driveway, and they complied with my request. I also asked them to level the compressor pad which they did. The defective circuit board was replaced, and backup electric heat came on. It took two Overlake techs until 7:00PM to connect the inside and outside units of the heat pump, and attempt to charge the system with refrigerant. However, a valve on the compressor unit was leaking so the heat pump could not be operated until a new valve was obtained and installed the following day. Day 3: Two Overlake techs arrived at 1:30PM, and, I assume, they installed a new valve. What appeared to me that was left to be done at that point was to charge the system with refrigerant, connect a small electrical cable between the inside and outside units, insulate the refrigerant lines, and spot-tie the lines and wires into a neat installation. This seemingly small quantity of work took until 10:00PM to complete, at which time it appeared that I had a working system. Day 4: I had programmed the wi-fi capable thermostat using the owner’s manual on Day 2, so I woke up on Day 4 to two emails from the system telling me about urgent notifications that had occurred in the middle of the night. They were Error Code 99’s – High Torque Lockout. A google of this returned a manufacturer’s document that explained this code was likely due to overcharging the system, and resulted in the compressor shutting down for a while and then restarting for a couple of hours when the error situation occurred again. I called Overlake and they said to run the system only on the electric backup until a tech could come out 4 days later. I think Overlake should have sent a tech out that day since, at that point, they were already two days late providing me with a working system. Also, since my old but still working heat pump had been turned off 3 days before, I was going to be using electric backup for 7 straight days (at least), and that more than doubles my heating bill, at this time of year. Days 5 thru 7: Waiting for tech to return and troubleshoot error code. Day 8: Appointment for tech was scheduled for between 11:00AM and 1:00PM. Tech arrived at 4:00PM, but did call to say he would be late. Between 4:00PM and 10:00PM, the tech removed the refrigerant from the system and then recharged the system with refrigerant. He had determined that the initial charging had been below spec (too little refrigerant was used), and he said that the system should work OK now that it was properly charged. After the crew left, I noticed that there was dirt, installation scraps, and some kind of cream-colored lubricant on the carpet next to the air handler, as well as trash in the crawl space and outside around the compressor unit. In general, they could have done a better clean up. Also, they apparently used the top of our clothes dryer as a work bench since there was a drop of dried, blue PVC solvent on the dryer along with many dirty finger prints. The system has now operated for 5 days without any obvious problems. I now have an installed and operating system; however, given that it arrived from Bryant with two faulty components, and the installation included two wires not connected and improperly charging of the system, I have little confidence in my new Bryant heat pump. However, among all the negative aspects of this project, there were a couple positives: Overlake’s price was almost $2000 lower than their competition, they promptly submitted the necessary data to Bryant for the rebate I was due, and they appeared to provide a neat and proper installation."

"It turned out Cozy Heat is not a distributor of our furnace brand, however they did find out for us that it is still covered under warranty for parts, but not labor. We were quoted what the cost of labor would be for them to install. He attempted to contact the furnace brand people for more information and was transferred to a number that said they were not open at that time (imagine that - after 9:00 a.m. on a Monday morning). He asked his secretary to check into that and call us back. She did very promptly. We were told we might want to get a 2nd opinion to decide on an 11 year old furnace whether we want to have a new furnace installed or have just the heat exchanger replaced. At this time we are planning to meet with a different company for a 2nd opinion. But even while we are waiting to do that, we are leaning towards having Cozy Heat replace the whole furnace.
The indecision is that reading online customer reviews about the different furnace brands, I don't see a furnace that stands out with customers and quot;very satisfiedand quot; more than and quot;very unsatisfiedand quot;. Seems like the reviewed furnace brands people are consistently 45% very satisfied and 55% very unsatisfiedand quot;.
Not sure how this story will play out.

Install Boiler questions, answered by experts

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model. 

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

Heat pumps are significantly more efficient than boilers, typically providing three to four times the amount of heat for the electricity they consume. While boilers run on fossil fuels, heat pumps use only electricity. This efficiency can lead to long-term savings on operating and maintenance costs. However, heat pumps have a higher upfront installation price compared to boilers. Despite their lower efficiency, boilers remain a popular choice for many homeowners, with 8 million in the United States alone, due to their lower initial cost and less intensive installation process. Ultimately, the best choice depends on your home's infrastructure, your budget, and your personal heating priorities.
