"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 FAQs, answered by experts

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.
