"The technicians were friendly and knowledgeable. The end product was excellent. The office was professional (mostly). The price seemed fair, but I would venture a guess that I could find cheaper, but I wanted a quality installation. I can confirm I found competition that was much more expensive. The only issue I had was scheduling both the quote and the work. In this case we needed both an electrician and plumbers complicating the situation. We scheduled both disciplines to quote on the same day. The electrician missed the window and had to come the next day. For the work to be performed, we again scheduled for a single day process but due to illness apparently had to reschedule for the following day. At that point, I complained to the office due to the inconvenience of taking 4 days out of the office for a 2 day job, looking for a little price reduction. The office manager I spoke to was more interested in defending their position than seeing my side. In the end he granted me a $50 online coupon, reduction yes, but I'm not sure why I wouldn't have been entitled to that regardless. Honestly, in the end I was happy and would hire again due to the quality of work, reasonable price and professionalism in general. They would have received high marks across the board if it wasn't for the scheduling issues. I hope that was just bad coincidence."

"I've been pleased with Polar Bear since they installed my A/C 16-17 years ago. Always prompt response to any problem, always knowledgeable professionals. Now it's time for a new system, I was walked through my options with no pressure to spend more, just the info on variables, and an offer of a discount, and very flexible deposit/payment arrangement. Great company."

"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

"September 2019, my water heater broke and TC HVAC Services replaced it with a new water heater. And they also fixed my AC and fridge. Recently, in October 2019, TC HVAC Services installed a new humidifier in my home. Mr. Thea Chea, the specialist was professional, honest, and he answered all of my questions. The repairs and installation were completed in a timely manner. And costs were reasonable and fair. I would definitely use TC HVAC Services again and I have recommended TC HVAC Services to my family and friends. Thank you, Mr. Chea and TC HVAC Services LLC."

"Consumers Choice has been my go to hvac contractor for 8 years. Recently, I had a leak in the closed loop water source that feeds into my hvac. CC replaced hoses and valves and got cool air going again. I never call anyone else."

"They were excellent.  The house I bought had a 27 year old hot water heater.  It was obviously on its last leg.  When it nearly stopped providing hot water, I called my home warranty company, and they sent Modern Mechanical.  The technician was so nice and honest; I felt as if he was a long-time friend.  He explained the advantages of a tankless system and since I was getting money from the home warranty that it would be worth the difference I would have to pay.  After installing the system, the kitchen faucet didn't have good pressure, so he replaced it for free.  He even worked to get one that looked like the one I had.  They were absolutely wonderful and I would definitely recommend them to anyone.

"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."

Install Boiler questions, answered by experts

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

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.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.
