"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

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

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

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.
