"My shower was horribly backed up, I called 3 Mountain and scheduled a next day appointment. Logan Greeno came out, he was extremely professional, he showed me what was wrong, gave me options about what could be done to fix it, and was 100% clear with me about pricing. He even pointed out some of the older pipes, so that I can get them checked out in the future before they become a problem. All in all this was excellent service and I am very satisfied."

"Sunset came out first thing on a Monday morning. They were able to diagnose and fix my issue quickly. Great job. We also talked about future work. My only issue was that the final bill was not the price quoted. There was another charge for them to come out to the house. That was never discussed by the office when they originally spoke with me. Effectively it was a hidden fee. Please be transparent up front."

"I contacted the branch of this company in Clackamas, since they had performed a heating system checkup in 2015, and I was impressed with their attention to detail and professionalism. I called them around 830 AM, and they were booked for the day, so we scheduled a visit for the next day. The tech (Paul) called and arrived as scheduled. He did a diagnosis and needed to order a part (sequencer) to get the furnace working again. At the time Paul wrote up the service order, we agreed that he would replace the fan relay as well as the sequencer. He then presented me with a bill for $458, which included a 5% Angie's List discount. Paul came out with the part the next day and got the furnace running again. I was disappointed that the fan relay had not been replaced, and after checking Amazon and a couple of other parts sites, found that a sequencer should only cost $30-$50! I called the office and complained about the excessive bill, but they did not want to talk about it. I felt that I was gouged by this company for this repair. I understand that there are labor and equipment expenses associated with the repair, but I believe that this was still too much, especially when all the requested repairs weren't completed! I believe that the amount should have been half or less that what I was billed."

"One of the men came, wore the blue booties so as not to track outside dirt, and opened the furnace, vacuumed the interior out, checked the filter, oiled any parts that needed it, and checked the furnace by turning it on to make sure everything was in good working order. He then made sure the entire area was cleaned up and took everything with him. I have used Mr. Nash's services since 1993 and have always been pleased with them. They are very professional, come when scheduled, never leave a mess, and make sure the furnace is in good working order. I will be calling in the next week or 2 to book this year's cleaning and servicing.

Boiler Repair FAQs, 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.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.

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).

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.
