"It went very well. They did a good job. The cost was over $400. I don't know whether or not that's too high or not. I seldom have plumbers in so I can't say the cost was high, although I was surprised it was $400, but that could be the going rate. He seemed very agreeable and very happy. I needed something and he was happy to get it. He was very knowledgeable and helpful in that regard. As for the quality of their service, so far so good. Everything went okay. It stopped leaking."

"I had been told by a repairman from a company I had a service contract with that my furnace badly needed a cleaning and was quoted a price of $600 for the job as well as an additional $400 to remove a nonworking humidifier. These quotes seemed exorbitant and so I got some estimates, all much lower, and chose Dominion on the basis of reviews. Terrone said my furnace did not need a cleaning, passing up an opportunity to charge me for something I thought I needed, and repaired my humidifier for less than the cost the other company had quoted for merely removing it. He showed me what he was doing, explained how my heating system worked, and charged me a fair price for the job. I would certainly call Dominion again for any HVAC needs."

"Briggs Heating and Cooling has been our go to provider since we renovated our home in 2005. They are experienced, supremely responsive and personable professionals who truly care about their customers. They go out of their way to get it right. We have trusted them so much that we introduced them to my elderly parents’ home years ago. My parents have adopted them ever since. We have had several projects this year alone, some routine maintenance, some much more complicated. Each project was handled the same way. First, my parents have an old AC and “Trevor’s guys” come out every year to service it. Their gas heater required a new switch which, because it was an old unit, took a lot of effort to find and replace. Next, our newer AC had a valve malfunction, and Briggs’ went way out of their way to properly diagnose the problem. As a precaution, we received a second opinion. Not only did Briggs’ diagnose the problem properly, they fixed it at about a quarter of the cost that the other service provider would have charged. Most recently, a couple of weeks ago, a leak was detected in my parents’ newly installed gas fireplace logs which Briggs had not installed. They met me at my parents’s home within an hour and had it repaired in another hour. And their prices are always extremely reasonable. This is small business done right. In northern Virginia, they are a breath of fresh air."

Boiler Repair questions, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

If you don't clean a boiler, you may have higher energy bills or no heat. A dirty boiler is inefficient and can't properly maintain a heating system. It may break down more often due to corrosion or clogs from soot and oil buildup. Cleaning a boiler improves its performance. The cost to replace a boiler can be expensive, so keeping it clean is a cost-effective practice.

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.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.
