Services
When we started Hearthstone Heating and Air Conditioning years ago, we had one goal in mind - providing area families with comfort solutions that fit not only their lifestyle, but also their pocketbook. We offer expert installation and maintenance by a skilled team of factory-trained professionals.
Whether your air conditioning unit is a single-room or whole-house system, old or new, it is a sophisticated appliance, and when problems occur, you need the help of trained professionals. Procrastination can sometimes lead to more extensive damage to your equipment. Rely on the licensed technicians from Hearthstone Heating and Air Conditioning, Ltd. to determine the extent of the problem and resolve it quickly. Our team is fully insured, EPA certified, and factory trained to handle everything from minor calibration to complete system replacement.
Your cooling system is a significant investment. Neglecting its care can turn into a costly mistake. Dirty, faulty equipment will need to work much harder to reach preferred temperature settings, consuming unnecessary amounts of energy for less cooling power. As integrity of the system is compromised, added stress is placed on individual components, leading to frequent repairs and shortening the overall lifespan.
If you're in the market for air conditioning in and around DuPage County, call Hearthstone Heating and Air Conditioning, Ltd. at 630-435-9800 and we'll get started designing the ideal system for your exact needs. We understand the intense heat and brutal humidity of Westmont summers, and know what it takes to guarantee dependable, energy efficient and quiet relief.

Our AC was not cooling our home on these very hot days. It worked but it wasn't keeping up. We were sure we would have to buy a new AC but Paul came out and totally fixed everything perfectly. He was very professional, kind and knowledgeable. Will definitely request Paul if we ever need help with our AC or heat. It works perfectly now!

Hearthstone installed my new furnace yesterday. I was extremely pleased with the entire process. Each person on their team was very knowledgeable and professional. They all took the extra time to make me aware of all my options and to make sure I understood and to guide me through these options before finalizing. The firm's president came to my house and spent nearly 2 hours to fully assess my needs to in order to recommend the best system for me. I trust them completely and would definitely recommend them.

Zak came to my home yesterday, and he saved the day! My AC was not working properly. He was quickly able to diagnose and correct the issue all for a reasonable price. Even more impressive, I called to schedule and appointment, and Zak arrived within two hours of my initial call. I will definitely be using Hearthstone again!

Paul was fantastic. I called at 7:00am when we woke up to a 59 degree house on a very cold day. By 8:00am Paul was here. Had the problem diagnosed by 8:05 and by 8:35 the motor in my furnace was replaced and heat was on! Fair prices, personable service and extremely fast without any "emergency fees" or anything like that. Would recommend and will be using Hearthstone again if the need ever arises.

Hearthstone HVAC is the best. At 3 a.m. this morning I woke up to a cold house. After 15 minutes of troubleshooting, I left a message on their answering service. I was called back in 5 minutes and a repair man was at my house by 5 a.m. Turns out loose garbage had wrapped itself around my furnace exhaust pipes and that is why the furnace would not start. They are reliable, courteous & honest. I would definitely recommend them to friends and colleagues.

I was more than impressed with Hearthstone. I called at 7:45 the day after Christmas, in the midst of a polar vortex. They had a repairman to my property within 30 minutes. Furnace was repaired in an hour and the service man, Zack, was incredibly nice and professional.

Although we had a mild winter, my furnace stopped working and it was cold inside my home. I called Hearthstone Heating in the early hours and the service center said they would page a technician. Within the hour the technician called me and asked me questions on what was happening. He was able to diagnose the problem over the phone and he said he had the part on his truck.

He arrived and verified the situation and replaced this part. He said it is a common problem and they usually always have the parts on the truck with them. I was really impressed. My neighbor gave me their phone number and now I have it on my fridge.

Hearthstone Heating has always been there for me when I needed them. The new equipment that they installed is terrific and has saved on my utility bills considerably. I really can not compliment them enough and I would recommend them highly to anyone!

Hearthstone replaced my furnace and a/c ten years ago. I have them out every year for a clean and inspection. They are prompt and their servicemen are competent, neat and thorough. And easy to talk to. I highly recommend them.
