"I have an annual contract with R.W. Harrell's Pump Service to clean and service the heating and A/C systems at my home. Their employees and always prompt, courteous and professional and ALWAYS do an excellent job with cleaning up before they leave. Their prices are reasonable and I like dealing with locally owned companies as opposed to the nationally owned companies. I would highly recommend R.W. Harrell to all of my friends and relatives for their HVAC needs.

"I recently had a crack in my acrylic bathtub and called TriState Home Services to replace the tub. We decided to replace it with the same soaking tub to avoid any unnecessary damage to the ceramic tile we put in a few years ago. Bryan, the plumbing specialist at TriState did just that! He did an awesome job on this project. I also want to say how impressed I was with their customer service department, particularly with Megan, in her quick response to my emails along with making me feel so comfortable throughout the whole job."

"The entire experience from the salesman - Adam Shapiro through the installers Shane and Sean went smoothly, quickly and professionally. Everyone was also extremely personable and helpful. I had shopped around and Weather Master gave me the best price for the specific equipment that I needed and installed it quickly. I plan to switch my annual maintenance plan to this company. I highly recommend this company!"

Install Boiler FAQs, answered by experts

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.
