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."

"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."

Our Company’s mission, quite simply, is to live up to our name! Definition of Integrity. In-teg-ri-ty (noun). INTEGRITY is a concept of consistency of actions, values, methods, measures, principles, expectations and outcomes. In ethics, INTEGRITY is regarded as the honesty and truthfulness or accuracy of one’s actions. Additional phones - (815) 723-2711, (630) 343-0778. Additional emails - [email protected] and [email protected]. Cost is determined by the job. Additional Web address - www.WeHaveIntegrity.com.

"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 questions, answered by experts

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.

Yes, including optimizing settings and suggesting upgrades if needed.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

An evaporator or swamp cooler is a common alternative for small spaces. These coolers blow moist air into a space to help cool it down. They are more affordable than misters and use much less water. However, coolers will not have the same cooling effect as misters, cannot help plants survive the heat, and only reach a small area.
