  • Why is my HVAC system making strange noises?

    Those odd noises could be clues that something is wrong with your equipment. It could be anything from a loose part to a clogged air filter. Our Illiana Heating & Air Conditioning repair experts can fix minor issues before they turn into costly problems.
  • Should I repair or replace my equipment?

    Repair your HVAC equipment if it is brand new or only a few years old. An exception to this rule is if the repair cost is too high-such as a cracked heat exchanger that is no longer under warranty. It may make more sense to purchase a new system, particularly if you want to upgrade your equipment.

At Illiana Heating & Air Conditioning, we guarantee our repair work with a warranty. Call us today to fix your HVAC system.

HVAC Installation and Replacement Services

You can trust Illiana Heating & Air Conditioning to install, repair, and maintain your heating and cooling equipment the right way so it runs quietly and efficiently.

  • How much does a new HVAC system cost?

    The price is determined by the size of the unit and the features. A variable-speed furnace, for example, costs more up-front but uses less energy to operate. You can trust Illiana Heating & Air Conditioning to provide transparent pricing and quotes so you are educated and comfortable with any purchase decision you make.
  • When should I replace my HVAC system?

    Well-maintained HVAC equipment can operate efficiently for 15 to 20 years before parts wear down and struggle to keep up. Are your energy bills increasing every year? Are your repair calls more frequent? New equipment reduces your carbon footprint and provides peace of mind.

HVAC Maintenance Services

Illiana Heating & Air Conditioning can tune up and restore your Crown Point, IN, heating and cooling equipment so you can enjoy it for years to come. We recommend a furnace tune-up in the early fall and an air conditioning tune-up in the spring.

  • How often do I need to maintain my HVAC equipment?
    Routine maintenance keeps your warranty valid. Maintenance also keeps your HVAC equipment running as efficiently as possible, lowering your energy bills. It's like changing the oil in your vehicle.
  • What are the benefits of professional HVAC maintenance?

    When you schedule an HVAC maintenance visit, your equipment will be inspected and cleaned. If there are problems, one of our Illiana Heating & Air Conditioning professionals can diagnose and resolve them right away! According to the U.S. Department of Energy (DOE), you could save up to 30 percent on your energy expenses with regularly scheduled maintenance visits for your HVAC system. Maintenance will practically pay for itself!

Be sure to ask about our Goldstar Maintenance Plan that we tailor to fit your budget and equipment. Maintenance agreements are a worry-free way to ensure you care for your HVAC system and guard against costly repairs.

Customer Reviews

“Our 5 STAR recommendation for the Illiana Heating & Air Conditioning, Inc. team. Great cooperation and work.
It all started with our phone call to their office in mid-June 2025. Our AC was not working properly. Patty helped us from the beginning. She gave us a choice of 1) a diagnostic service visit (next day) or 2) full repair service (four weeks out). We opted for the next day, which was actually an “emergency” service trip assigned by service address location to be as efficient as possible. The Illiana office stayed in touch with us during the day and gave us about an hour's notice of the visit time (no actual appointment time). This was immediately confirmed to us via text.
The next day, their text messages started at 7:33 AM, just saying we were on the day schedule and they would give us about an hour’s notice before the technician would arrive. Another message came at 10:03 AM, and the next at 1:01 PM. At 2:58 PM, Jerry B, Illiana’s Technician, sent notice he was on his way. The notice included an introduction and the technician’s photo for identification.
Jerry got to work right away, starting with the indoor system and then the outdoor system. He took several measurements and found a few values that did not add up. He went back into the furnace and accessed it with a scope camera. He found that the refrigerant valve was not functioning. Jerry was able to quote the replacement part and labor cost right there. However, he also noted that our Heating & AC system had been installed in 2008, making it 17 years old. We asked what a replacement AC system would cost, and Jerry referred us to Dan Krysheld for this system estimate. Jerry took photos and measurements and sent them to Dan, making an appointment with him in two days.
However, later that day (early evening), we received a text from Dan asking to clarify a couple of items. We did this, and in less than an hour, we had a complete proposal, which included an A/C system change-out and a Furnace with an AC change-out. Illiana promised to schedule the change-out within two workdays. Since the existing system was 17 years old, we decided to replace it all.
The installation was scheduled for the promised time, and Adam and Sam were at our house, ready to go a little before 8:00 AM. They worked together like an organized team should. They positioned all the new equipment, with one taking the outside and the other taking the inside. They worked efficiently and made the installation look very professional. They redid piping, furnace intake and exhaust, wiring, ductwork, and monitoring. The complete cleanup was done with care and thoroughness, including sweeping the floors. They were done around 3:00 PM and then took the time to explain the system’s operation and the new components.
