REPAIR SYSTEMS

AC Repair

When your air conditioner stops working properly, you need an experienced local team that can identify the problem and restore your comfort.

SYSTEM MAINTENANCE

AC Maintenance

Your air conditioner works hard to maintain a comfortable indoor environment throughout the summer. Over time, dirt, normal wear, loose electrical connections, clogged drains, and restricted airflow can affect its performance. Without regular maintenance, these concerns may contribute to higher energy use, reduced cooling capacity, or premature equipment failure.

What Hinsdale homeowners say.

★★★★★
"My self-contained wine cooling unit died, and I feared it would be a huge task to replace. Cardinal came out and installed a new one in an hour and a half. Extremely friendly, very clean work, and even took the old unit at no extra cost. They went above and beyond in every way, and I couldn't have asked for a better experience."
Jeff W.
★★★★★
"Cardinal HVAC is the absolute best. Don’t waste your time with others. Not only are they very professional and do excellent work, but they’re honest and friendly. Quick example, I had an AC problem and a couple companies came out and said it would be about a $3000 job. Cardinal came out and said it actually wasn’t a big problem and fixed it for a few hundred bucks!"
TJ B.
★★★★★
"Cardinal was great. Called them for a second opinion after the first company told us we needed a new furnace. The tech from Cardinal, Jordan, was very professional and thorough. His diagnosis was that our furnace needed a little TLC. Did not identify any major issues. Told us about their bi-annual service program and how they could help us extend the life of our HVAC system. Highly recommend."
Matt D.
★★★★★
"Cardinal heating and cooling is great! We had a panic one evening after hours during below 0 temps when our heater wasn’t responding. Cardinal responded immediately with troubleshooting steps and walked us through what to do. What they suggested worked and our family was able to sleep cozily that night!"
Rachel M.
★★★★★
"Every person I’ve interacted with at Cardinal has been knowledgeable, respectful, solution-oriented, and refreshingly honest. They’ve truly worked miracles keeping my older system running efficiently and reliably for as long as they have."
Arielle Z.
★★★★★
"Great responsive service. We have used them for the past 5 years + and never disappoint. We have dealt with both the owner on a holiday and Jordan several times which is nice to have consistency. very nice and professional. They don't try to fear monger or scare you with expensive solutions either. Trust worthy."
