"My overall experience was excellent! From the very beginning, the salesman, Austin, was absolutely amazing very knowledgeable, very pleasant and went way above and beyond to get things ready for my installation of a new heat pump system.The installation crew that came the following day was also absolutely amazing. I would highly recommend this company to anybody and will definitely contact them with any additional needs I may have. I’d like to thank each and every one of them for doing such an excellent, professional job."
We are a small family owned Heating, Ventilation, and Air Conditioning (HVAC) company located in Sharpsburg, MD. The business was started in 1989 under the name of RW Harrell's Pump Service Inc. when Diane Harrell and Ronnie Harrell purchased a well pump and water system business from a gentleman that was retiring. Ronnie had worked in the HVAC field from the time he had graduated from high school so it was natural to add HVAC to the services that this new company would offer. Ronnie and Diane built the company by word of mouth and continue to grow the company in this manner. Additional DBA - Harrell's Services. Additional fax - 928-492-8004
"It was pricy, but it was good service. Well, that's hard to say because it's all expensive, as oppose to any other air conditioning company, it's about the same, just too much money in general."
"Work went per plan. Skilled technicians knew their product and had experience with installation. Clean neat job that was done right the first time. Removal of the old unit and air handler went as planned."
"They do a great job. Had a furnace installation and ongoing maintenance over the years. We have never had a problem. Very professional and qualified."
"American Construction was a great team to work with. They remodeled my bathroom, helped with the design, took care of all the materials after I made my choices. They were very responsive to all my questions and requests. Now I have a beautiful and functional bathroom."
"We would definitely recommend Good Shepard! He has done work for me in the past as well as recently doing a complete installation. They completed the job on time, had a friendly crew, and the work area was always left neat. They were knowledgeable and polite. Happy with unit installed."
"It didn't. Like another poster wrote, I also tried contacting him a few times and the last two times, no response. I ended up hiring another company. I did hire this gentleman about a year and a half ago and he and his colleague did great work. So, I was hoping to hire him again - no such luck this time!"
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.
Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
Most installations take 2-5 days, including old system removal and setup.
The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics.
Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.
No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.
While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.
