Heating Maintenance in New Lenox, IL
The cheapest repair is the one you never need.
Some homeowners in New Lenox, IL, neglect heating maintenance as long as the system seems to work fine. Note that heating systems tend to accumulate dirt and grime with continued use. Some components also experience natural wear and tear, and if you fail to inspect your unit regularly, it might fail sooner than expected.
One common problem with a neglected heating system is carbon monoxide leaks. It also reduces the unit’s efficiency and results in inconveniencing breakdowns. Luckily, Zark Heating & Cooling offers exceptional furnace maintenance to keep your unit in top shape all year long.

Reliable heating maintenance in New Lenox
You will likely run your unit for a more extended period during winter. So, get a heating tune-up before the beginning of the cold season to prepare it for the workload. A neglected unit tends to work harder to maintain the desired indoor temperature, resulting in high energy use. During tune-ups, the technician will clean off dirt, lubricate moving parts, tighten loose connections, inspect the ductwork, and test the controls. All these activities contribute to efficient operation, lowering utility bills. Maintaining your heating system will also help preserve the warranty. Most manufacturers require proof of regular unit maintenance before covering repairs and replacements.
During tune-ups, the technician will clear off pet dander, dust, pollen, mold, mildew, and bacteria from your system. This improves indoor air quality and eliminates allergy or asthma triggers. A clean and well-maintained heating system improves your home safety. It helps prevent gas leaks and electrical faults. Such a unit is also less likely to break down. A technician will identify and fix minor problems early enough before they escalate into more significant issues.
A neglected heating unit won’t blow adequate air into all rooms of your house. But after tune-ups, your unit will maintain a greater level of comfort. Some signs that you need to have your heating unit tuned up include:
- You hear strange noises
- You smell unusual odors
- Sudden increase in utility bill
- Uneven distribution of heat

Preventative Maintenance Plan
Our annual Preventative Maintenance Plan (PMP) covers one visit in the spring or summer to clean, check and tune your AC, and one in the fall or winter for your furnace. PMP customers get priority service, up to 20% off parts, refrigerant and repairs, and a $50 diagnostic or service fee for emergency service. See the full plan.
Most no-heat calls in January are preventable. A tune-up catches a cracked igniter, a clogged filter or a failing capacitor while it's still a small job — and keeps the system running at the efficiency you're paying for.
