"Before, we only had a localized very old gas floor furnace. Total Home Environmental installed a centralized Heating/AC system in the attic and insulated the attic as well. They installed vents and ducts (first time for the house). They did a good job."

"My water heater was leaking but glad that I contacted water heater only. I called at 10:00am and by 12pm they were here installing my new water heater. David from Water Heaters Only came in the afternoon of 6/12/18 and it took 2 hours to install to city and state code. He had all the parts and tools to change the water heater on the spot. Old heater was taken away and new heater installed by 2pm.. I would highly recommend Water Heaters Only. They were very professional and courteous."

"The access panel on the unit was slightly bent as was the unit. Instead of repairing the installers taped it up with duct tape. The panel fell off and I had to call for another service man to come out and correct the problem. The second technician did a much better job."

"Joe was amazing. He not only found a better A/C unit than the one we we were looking at (for even less than what we had originally budgeted) he also installed it perfectly. When we had a small issue (turned out to be low FREON) Joe came, replaced a valve and fixed it perfectly. Our new A/C is working great and Joe has been amazing to deal with. We would hire him again in an instant."

Install Boiler questions, answered by experts

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.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.
