"We purchased a new central air conditioner and a 2-stage furnace. In addition, they needed to update the air circulation to and from the system, which was nicely done. Needed a little tweaking, and one of the owners came out to perform the simple task himself."

"Excellent service. During a kitchen remodel, contractors cut tile with a wet saw in the kitchen instead of outside or in garage; tile dust scattered through the entire house. Called Mr. Duct to clean all ducts. Cesar and Ulysses did an outstanding job. Fast, professional, courteous. This is my first experience with duct cleaning and I am very satisfied with results. Definitely recommend Mr. Duct."

"on time, and knowledgeable the technician did the job well. Also, I had a problem changing the furnace filter. The filter was getting stuck when taking it out or installing. He repaired that too."

"I have had this company service my furnace and air conditioner for years. They are a small, family owned and operated business, local to me. All things I like when looking to hire. Jim and his people have always been honest, professional, reasonable, prompt, careful, friendly and I trust them completely. Before Vent, I tried a few other companies. They seemed to always find something that needed more attention, and more money. By contrast, I have an air conditioner that is quite noisy. At least 5 years ago, I was told, by Vent, that it probably wouldn't last much longer. But since it still seemed to cool OK, they just cleaned it. It is still going. Now, they could have told me it had to go. But their honesty bought me another 5 years or so without that major expense. That would never have happened with any other company. In the end, what gives them a 5 star rating is their integrity. I can't ask for more than that."

"We had five companies come out and look at our house and give us quotes for installing a Spacepak or Unico system in our house. Phoenix gave us the lowest quote (16k less than the highest quote!) and also had the best customer service. Everything was explained to us before, during, and after the installation. The owners seem to have a genuine passion for HVAC, which I wouldn't necessarily expect! Anthony was great with figuring out ways to get air to all the rooms in our 110 year old house with many quirks. Glad to have found this company."

FAQs for central a/c service or repair projects in La Grange, IL

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
