"It went very well. This is the third time that we have used Green City Heating & A/C. In the past two years they have installed a new gas furnace boiler, two gas fireplace inserts and now a new gas hot water heater. In each instance, Jeff and his crew have been very prompt about attending to our requests and providing us with an estimate. On the day that the work was to be done the work crew has always arrived on time and finished the job as scheduled. They have been very professional to deal with. We are very appreciative that they were able to work us into their schedule so quickly this last time as going without hot water is a bit of an inconvenience. Green City Heating is our first choice when it comes to our home's heating and water systems."

"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."

"Noel replaced two water heaters and installed hot water line so I can wash car with warm water. :) Overall, I am very happy with the quality of his work. He is very patient and took time to do quality work. Before he start on the project he laid down paper on carpet to protect it and he cleaned up everything after he's done. His pricing isn't the cheapest...but I would say average. In line with what other plumbers charge to the same work. I would recommend All Pro Plumbing to anyone and would use them again if I have future plumbing work! Thanks!"

"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."

"My existing furnace died and we were without heat. I was not happy with my existing HVAC company so I considered 4 competitors. I had Rob of Overlake come out. He showed up on time, explained and proposed several alternative solutions, and gave me a quote a few hours later. It took me a couple of days to get quotes from others, and I ultimately decided Rob's was certainly the best. Knowing we had not heat, he was able to schedule the installation within a day of my selecting Overlake. His guys had quite a bit of sheet metal to replace in the process of installing the new furnace. They did a great job, were very punctual and professional. I am totally satisfied with all Overlake did."

"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

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.
