Trusted HVAC Maintenance For Your Home

Keeping your heating and cooling system in top shape is one of the smartest investments you can make for your home or business in southern Illinois. Our unpredictable weather means your equipment works harder than most. At Collards, we provide thorough HVAC maintenance that helps your system run efficiently, avoid breakdowns, and deliver dependable comfort year-round. From the older homes in West Frankfort to the newer builds in Carterville, we make sure your system is ready for whatever the season brings.

Why HVAC Maintenance Matters

In our part of Illinois, temperature swings can be brutal. A hot, humid July day in Marion can push your air conditioner to its limits. Then, come January, a deep freeze in Benton can strain your heating system. Without regular maintenance, those swings can wear your system down faster, cause higher energy bills, and lead to costly repairs. Maintenance is not just a good idea here, it is essential for keeping your system running reliably.

Benefits of Routine HVAC Maintenance

  • Lower Energy Bills – A well-maintained system runs more efficiently and uses less energy.
  • Fewer Repairs – Preventive care helps stop small problems from turning into costly fixes.
  • Longer System Life – Regular maintenance can extend the lifespan of your equipment.
  • Better Comfort – Proper adjustments help your system keep a consistent temperature in every room.
  • Improved Air Quality – Clean filters and coils reduce dust, allergens, and pollutants in your home.

Seasonal Tune-Ups for Maximum Performance

We recommend two maintenance visits each year, once in the spring for your cooling system and once in the fall for your heating system. Spring tune-ups get your air conditioner ready for the high humidity days in Herrin, Pittsburg, and Carbondale. Fall tune-ups prepare your furnace or heat pump for those cold snaps in Sesser, Cambria, and Zeigler.

Serving the Communities We Call Home

We know the local climate and we understand the demands it places on your HVAC equipment. From homes in Spillertown that deal with heavy pollen in spring, to rural properties in Mulkeytown where dust can build up in ductwork, we tailor our maintenance to your specific needs.

When to Schedule Your Next Service

If it has been more than a year since your last tune-up, or if you have noticed higher energy bills, uneven heating or cooling, or strange noises from your system, it is time to schedule maintenance. Acting now can save you money and stress when the next heat wave or cold snap hits.

Keep your system running strong. Call Collards today to schedule your HVAC maintenance service and enjoy worry-free comfort all year long.
