"He got back to me in about an hour and a half, said he could come out about 930 that morning. He was running a little bit late, but he did send a message telling me his arrival time, which I greatly appreciated. It was nothing major and he told me what to look for in the future, and how to take care of myself. Even took a look at my blower amperage and the furnace amperage to make sure they are doing OK. We would definitely hire him again."

"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."

"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 questions, answered by experts

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

Many HVAC manufacturers provide warranties that encompass the cost of a new compressor, with durations ranging from 5 to 10 years, depending on the brand. These warranties cover critical components such as the compressor, condenser, connecting tubing, evaporator, and refrigerant charge. Moreover, they often include the necessary labor for replacement or repairs. Keep in mind that premium-brand compressors may offer lifetime warranty options. It's essential to note that these warranties rarely cover labor costs.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.
