HVAC Maintenance in Bolingbrook, IL

Chicago-area weather is hard on heating and cooling equipment. Your furnace may run for months straight through sub-zero stretches, and your air conditioner gets pushed through humid July heat waves. A seasonal tune-up is the simplest way to keep that equipment running safely and efficiently — and to catch small problems before they turn into a no-heat call on the coldest night of the year.

Why seasonal maintenance matters

Better efficiency

Dirty coils, clogged filters and poorly adjusted blowers make your system run longer to do the same job. ENERGY STAR notes that dirty coils reduce an air conditioner’s ability to cool your home and increase energy costs, and that a dirty filter can damage equipment and lead to early failure. Keeping components clean and adjusted helps your system use less energy.

Fewer breakdowns

Many failures start small — a weak capacitor, a worn igniter, a partially blocked drain. A pre-season check can catch them while they’re still minor repairs.

Safety

A gas furnace burns fuel inside your home. A proper heating tune-up includes checking gas connections, burner operation, venting and the heat exchanger. A cracked heat exchanger or a blocked flue can allow combustion gases — including carbon monoxide — to enter your living space. Make sure your home has working carbon monoxide detectors, and if one sounds, leave the house and call 911 or your gas utility.

Warranty protection

Many manufacturers recommend routine professional maintenance, and some equipment warranties exclude failures caused by not maintaining the equipment according to the manufacturer’s instructions. Keep your service records and check your own warranty terms.

What a furnace tune-up typically includes

Checklists vary, but a standard heating tune-up generally covers:

  • Inspecting or replacing the air filter
  • Checking gas connections and gas pressure
  • Inspecting burner operation and flame
  • Inspecting the heat exchanger for cracks or corrosion
  • Checking the flue and venting
  • Testing the igniter, flame sensor and safety controls
  • Cleaning and checking the blower and verifying airflow
  • Tightening electrical connections and checking the thermostat

What an AC tune-up typically includes

A standard cooling tune-up usually includes:

  • Inspecting or replacing the air filter
  • Cleaning or inspecting the outdoor condenser coil and checking the indoor coil
  • Checking refrigerant charge against manufacturer specifications
  • Testing capacitors, contactors and electrical connections
  • Clearing and checking the condensate drain
  • Checking blower operation and airflow
  • Verifying thermostat operation and cooling performance

When to schedule

ENERGY STAR recommends a cooling check-up in the spring and a heating check-up in the fall, before contractors get busy with peak-season breakdowns. An easy way to remember: book around the daylight-saving time changes.

Signs your system needs service now

Don’t wait for your next scheduled tune-up if you notice:

  • Rooms that won’t reach the set temperature
  • The system turning on and off frequently (short cycling)
  • Banging, grinding, squealing or rattling noises
  • A burning or musty smell when the system starts
  • Water around the furnace or indoor AC unit
  • Ice on the refrigerant lines or outdoor unit
  • A yellow or flickering burner flame on a gas furnace

HVAC maintenance FAQ

Once a year for each system is a common recommendation: the furnace in the fall and the air conditioner in the spring. Heat pumps, which run year-round, benefit from a check before both heating and cooling seasons.

Yes. Many problems develop gradually without obvious symptoms. A tune-up can catch worn parts, dirty components and safety issues early, when they’re usually simpler to fix.

A heating tune-up includes inspecting the heat exchanger, burners and venting — the parts most often involved in carbon monoxide problems. It doesn’t replace working CO detectors, which every home with gas appliances should have.

Check your air filter monthly and replace it when it’s dirty, keep the outdoor AC unit clear of leaves and debris, and keep supply and return vents unblocked. Leave gas, electrical and refrigerant work to a professional.
