"I haven’t cleaned my split AC unit for over a year. Called Paradise Ac to come and check it out. Lance the owner was really professional and responsive. He cleaned out all the mold and dust in the unit that I couldn’t see. My Ac is blowing cleaner air and it makes a big difference. I highly recommend Paradise Ac for all your service needs."

"Not only was ultimate air on time, they did a good job cleaning our system, and now we can breathe clean air, keeping me and my family healthy. They also explain in detail why it wasn’t blowing as strong, and showed me how dirty it was, and explain that it needs at least a cleaning every six months. Definitely would recommend and will be hiring them again. Thank you ultimate air!"

Install Boiler questions, answered by experts

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

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.

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.
