"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."

"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 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."

"Amazing! The problem with my AC unit was a bit of a mystery. I had a service tech named in Fred who checked all the components before checking the brand new thermostat I had installed just six months prior. I don't think anyone would have even thought to check that since the furnace had been working fine in the winter. It had been installed wrong for A C though. He rewired it and my entire unit works fine. I'm certain the last two techs I had here last winter would have sold me a new unit which I really couldn't afford. Polite, informative, expert in this field, Fred and Air Control H&C are simply the best."

"We called about a noise in our A/C. When we initially called they told us that we would not be charged for the service as we have their annual plan. After the service person came out we were given a $218 bill that was due at time of service. My wife called the next to get clarification on the bill and was told we were not supposed to be charged 99 and that they would reach out to us to figure out how to get the money back to us. They still cashed our check and the service manager will not return our calls so we are out 99 dollars. We have been attempting to reach out for a month now and each time the Service Manager is "busy." Incredibly unprofessional. On top of this, the issue of the noise was not resolved and we had to have another tech come out and fix it again. The price for each visit was not consistent so I have to assume they make up prices as they go. First charge was for 119 (plus the 99 they were not supposed to charge) and second time out was 149. I would avoid paying this company if they come out to you until you get an itemized explanation as they will keep your money even after they admit they were not supposed to charge you."

Heating oil services FAQs
To buy heating oil for your house, contact local heating oil companies to compare prices and place an order once you decide on a supplier. The company will have to deliver your heating oil in a truck designed to carry and dispense heating oil safely. Call and order your heating oil early enough to have your oil delivered before you need to start using it for home heating.
On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.
You save money on heating oil in a few ways:
Make sure your home is well insulated and sealed against drafts and heat leakage.
Use a thermostat that’s working properly and calibrated accurately.
Increase energy efficiency by insulating your basement and attic.
Turn down your thermostat a few degrees.
Program your thermostat to lower the heat when you’re not home.
Order heating oil during the off-season when prices are likely to be lower.
Summer months tend to be when heating oil prices are lowest because of decreased demand. Buying heating oil during the off-season also prepares you for when the weather gets cold, and you need to start using the oil to heat your home. Although heating oil prices will fluctuate, it’s best to avoid purchasing between September and April, as that's the peak season for heating oil demand.
Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.
