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."

We are a Heating & Air conditioning company that specialize in heating & air conditioning installation and repairs.

"The technician was very professional and respectful of my home by removing and/or covering his shoes as needed. He kept me informed about his progress and issues he found as he continued his work. The furnace is very old, so he conducted research, determined the problem, got the needed parts and completed the job for a reasonable cost. I would definitely use his services again. 5 stars!"

"We had two technicians out over two days. One was for a repair, Daniel. He did a fantastic job troubleshooting and explaining throughout the repair process. As a retired VP of Services, I notice the details and process. They delivered. Louis was sent for a follow-up to service because our fan motor unit needed to be cleaned. All of this was very well documented with pictures and showing me the actual motor unit. Louis did a great job of explaining and showing me the actions and results. It was a service text book delivery of services. Really good... Plus, both technicians worked to save me money with discounts and customer loyalty savings. Fantastic... An honest group of technicians and a company that promotes that in the customers best interest."

"I had to replace my old boiler heat as it was not repairable. So I purchased a NEW wall-mounted, modulating gas, condensing, combination Boiler. It replaces BOTH my boiler heater & Hot water tank. The new unit is attached up on wall with a small tank, gas, water lines below. The 2nd pic is where old hot water heater used to sit. Now I have all that extra storage space!! And no need for upkeep & repairs on a big old hot water heater!! The only thing I can complain about was that they were here for 12 hrs!! start to finish. Plus I was here sitting practically on top of a space heater dressed very warmly all day. And of course this was in January 2025 in northwest Indiana. I think this was a 1st time install for them in an older home not a new build. I would have rated them as a 5 star if not for the LONG DAY it took to be installed. They all were very nice, kind & cleaned up their mess. They brought large painter cloths to put down on floors due to going in out in the snow also."

Heating and air conditioning services FAQs

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
