"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

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.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

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.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.
