"Called on Friday and they came out an gave estimate same day. Called them Monday morning and scheduled install on Wednesday. They were here Wednesday morning as planned and installed A/C. The two guys that came were very professional and did a great job. Once A/C was in they cleaned everything up. Would highly recommend them to friends."

"The project went extremely well and I am very satisfied! They arrived at a convenient time in the morning and finished faster than I expected the same day for such a big project. But ALL details were completed above and beyond simply installing the unit with top quality and professionalism provided by Ted, Mike and Anthony and left me very happy with the results! I would recommend their services to anyone looking for the 'best' service and quality in air conditioning and heat installation."

Install Boiler FAQs, answered by experts

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

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.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.
