"Great customer service! Josh and his team (Kevin and Chris - installers) were great from the first phone call until the house cooled down! Professional staff, took every precaution to keep our house clean while they worked, cleaned up afterwards....very customer focused. They met every timeline they provided. The ladies in the office staff were super friendly. Of note, it took a few days before we could get system installed. They delivered and installed window units in the den and bedrooms to get us through the hot days. All i all, a great experience and we can't recommend going anywhere else."

"I had some issues with my 10 year old furnace and started looking into issues. I used to work for Carrier as an HVAC researcher and tried to fix the issues myself. I disassembled the burner and tried to get things right. In the end, I exhausted options and gave up on repair. I called my serviceman, trying to have the furnace repaired. He recommended getting a new furnace or replacing the whole HVAC since it was more than 10 years old. My serviceman gave me a quote for a Carrier furnace, which I thought was high since I knew the price of the unit (ex-Carrier R&D engineer). That was when I decided to look around. I received three quotes after reading through reviews in google and Angie’s list. In the end, I chose ARS Manassas by virtue of their overall competitiveness. In any business, it takes two things to win a deal: trust and value. In my case, one salesperson, Cliff Allen (who I will talk about more in a minute) delivered both aspects, which made the decision easy. Since I know the HVAC system in and out, I had many detailed (and even tedious) questions, to which he answered professionally with knowledge and courtesy. He did not try to upsell anything. In fact, he recommended to check a few things for repair, even while giving quotes for me. Although I decided to get the new one in the end after trying a few more attempt for repair, Cliff earned my trust and respect in the meantime. He tried to provide an optimal solution in terms of price and performance, which was more competitive than the other two quotes. I ended up getting 16 SEER performance series furnace and AC. Cliff truly knew what he was doing during the selection process. He answered all the questions an ex-Carrier R&D engineer raised and provided several quotes for comparison, which helped me to reach a satisfactory solution in an efficient and rational manner. He never tried to upsell, clearly understanding customer’s side. To the contrary, he did his best to give me the best deal without compromising performance. His professionalism does not stop at sales. He went over all the items in the specifics of installation, meticulously jotting down any notables in the contract. I was not surprised to see the technicians, Michael and Melvin, show up on time and finish the job, following the specifics and notables that Cliff had prepared at the contract phase. They tried to make the installation smooth and went over every single item to make sure that it was done to perfection. About a month later, the town inspector came out and made sure that the unit had been properly installed. The inspector confirmed that the job was done to the standard but pointed out that it would be better to add another bracket to the outdoor unit so that it would not move around. I called ARS to inform the findings of the inspection. ARS has promptly scheduled another visit (even if they could have waited for AC checkup in the late spring) to fix the issue. This time Jeremy and Josh came out and meticulously fixed the issue. These two gentlemen really knew what they were doing. They went a lot further than just adding a bracket. The outdoor unit is so sturdily attached to the bracket now that even a hurricane would not shake the outdoor unit. My kudos to Jeremy and Josh. I will come back and write a further review in 6 months to report any issues I experience but for now, I am glad that I chose ARS Manassas for new HVAC installation. If you ever need a new HVAC near Manassas area, the choice is simple. Go for a trustworthy and knowledgeable man that would deliver the best value for your investment, Cliff Allen at ARS."

Install Boiler FAQs, answered by experts

Oil boilers provide reliable heating, efficiency, and long-term cost savings compared to electric options.

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.
