"They were fast and did great work. On the expensive side for what we had done (repaired leaking windows), but they got the job done."

We are family owned and operated. We service all brands, makes and models. From furnace and water heater repair and replacements, all the way to a leaking kitchen faucet or bathroom toilet. One call REALLY does it all. Faucets, toilets, sinks, drain rodding, water heaters, boilers, furnaces, air conditioners and humidifiers. New construction to radiant heat. You know you called the pros the first time. Licensed, bonded and insured, we offer easy approval and affordable financing as well!

"I’m extremely satisfied with Regional. We had three sump pumps that needed to be replaced (primary, secondary, and water powered backup). The quote was very reasonable, and they were able to do the work shortly after their initial visit. They replaced everything with Liberty pumps. Justin and Erich did the work and they were very professional. We had them quote out a couple of other items (replacing water heater, etc) and those quotes were also very reasonable. I will definitely hire them for future jobs."

"While the caulking job itself was fine, not much care was taken with the existing tub glaze. In the removal of the old caulk, the tub glaze was torn and scraped. Unfortunately, I was not very satisfied with the outcome."

FAQs for central a/c installation projects in Knox, IN

If you’re replacing an old AC system with a new unit, you can usually clean and repair the old ductwork without having to conduct a full replacement. Cleaning HVAC ducts typically costs around $400, while repairs range from $200 to $1,000. In contrast, installing new ductwork can range from $1,000 to $5,000, making it far more costly than cleaning or fixing existing ducts. HVAC installation costs an average of $7,000 to replace a full system, so staying on top of maintenance and repairs is important.

AC cost efficiency depends on the size of your space and your long-term plans for your home. If you only need to cool a small area, a portable AC unit has a low upfront cost. Heat pumps are typically the most cost-effective option if you want to cool an entire home or improve the resale value. They provide strong cooling while being energy-efficient, which saves you money on your utility bills compared to most other AC types.

Installing a central AC unit typically takes four to eight hours if your home already has ductwork in place. However, if new ductwork needs to be installed, this can add another one to two days of labor to your project.
