"Very impressed with the Technician and the work that he did. The Technician was here for about 6 hours. The Technician discovered a mold issue in the Air Handler blower wheel and thoroughly cleaned the unit plus chemically cleaned the evaporator. The Technician installed a UV light to prevent future mold issues. He thoroughly cleaned and sanitized the house duct system & inside air handler, cleaned condensation drain pan & line. Also installed a whole house germicidal UV Air Treatment System. As he took down each air vent I gave them a thorough cleaning. We are now on a six month maintenance plan @ $89 each."

"I wasnt happy with my existing HVAC Contractor so I called Air1 of Central Florida. Csaba came within few hours tested the system very methodically and diagnosed that drain pipe was clogged. He cleaned the pipe with pressurized nitrogen. His charges were reasonable."

"

Their professionalism on the phone and the courtesy of the first service call to our home lead us to hire them to install our new unit.  I checked out their web-page which was also very professional.  Also, Prestige came highly recommended from a Property Manager in Boca Raton, Florida, whom I trust implicitly.   My husband and I were most satisfied and intend to buy their yearly maintenance plan as well.

"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

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

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.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

Most installations take 2-5 days, including old system removal and setup.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.
