Come BEHOLD the difference! "Unfortunately we do not service or intall swamp or evaporative coolers".

"My water heater had gone out and called and called around trying to get quotes and big company’s were trying to schedule in person quotes which I know is a strong arm to get the work done then and there because they are already at your house ect. But with Behold I had a personal direct text from them asking about my situation and all I had to do was give some info send in pictures and voilà! They gave me their quote(2300$) which also beat all the company’s(3k$+) I had heard from! They had a tech out to me ASAP. It almost could’ve been same day but I was in no rush. Hunter came in and did it all him self of removal of old and installing new in just two hours! They are great to work worth and will definitely recommend and go to again."

"I hired Paramount back in 2020 for work on the first floor and appreciated their work so much that I brought them back for the basement (fix/ update after mold repair) and second floor (bathroom and stairs update, new carpet). Like the first time, I really appreciated Ryan's suggestions on style and options, and the various contractors were professional and very kind about working around me and the cats. Ryan was ultimately more critical than me about details and appreciate that desire to do things right and as clean as possible. Would use again!... although that would require a new house at this point. 😁"

Boiler Repair questions, answered by experts

You’ll want to bleed your radiators at least once per year, typically in the fall before you plan to turn on the heat. Bleeding a radiator is a regular part of your heating system maintenance, and you’ll need to do this regularly to keep these units running efficiently. You should also bleed radiators any time they start making noise, like gurgling, hissing, or banging.

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

Most repairs take 2-6 hours, but extensive repairs or part replacements may require a full day or more, depending on availability.

Regular maintenance includes annual inspections, filter changes, and checking for leaks or pressure inconsistencies to improve efficiency and longevity.
