HVAC maintenance services, also referred to as clean and check or tune-ups, are intended for homeowners without active system issues. Pricing includes $98.95 for one furnace or air conditioner, $114.95 for one heat pump, and $154.95 for one boiler. Each service includes system cleaning along with a 28-point inspection.

Members also receive two HVAC system checks annually covering both heating and cooling systems.

Preventive maintenance for HVAC systems is a scheduled tune-up that keeps your heating and cooling equipment safe, efficient, and reliable. Most problems it prevents start as small issues—like dirt buildup, loose electrical connections, or poor airflow—that turn into breakdowns and higher energy use if ignored. We service systems throughout the St. Louis area and often see that skipping even one season reduces comfort and raises bills. A skilled technician also compares readings over time to spot early wear before you notice symptoms. If you prefer a single visit, our $99 Clean & Check provides a thorough A/C or furnace evaluation to confirm performance.

During professional maintenance, you can expect:

• System inspection
• Cleaning
• Component testing and performance check
• Safety checks

Schedule maintenance before peak seasons to lower the chance of an emergency breakdown. <br/> Updated: 2026-05-01 <br/> Need help in Chesterfield, MO? Call 3148148455 or book online.

A typical HVAC maintenance checklist includes inspection, cleaning, performance testing, component checks, and safety checks for your A/C and furnace. Most tasks target airflow and safety first, since dust buildup and normal wear cause most efficiency losses and nuisance breakdowns. We perform these steps routinely for homes across the St. Louis area.

Common items you’ll see on the checklist:

• System inspection of A/C and furnace cabinets, wiring, and controls
• Cleaning of accessible components to remove dust and debris
• Performance and component testing to verify operation under load
• Check of refrigerant charge, voltage and amp draw
• Inspection of filter

For a simple option, our $99 Clean & Check bundles the inspection, cleaning, and a performance test in one visit. Our Preferred Partner Plan includes two HVAC system checks annually starting at $19/month.

At Air Comfort Service, Inc., annual HVAC maintenance typically costs $99 per seasonal Clean & Check per system, or starts at $19/month for a Preferred Partner Plan that includes two system checks each year. Most cost differences come from how many systems you have and whether you prefer one-time service or ongoing membership perks.

We service homes across the St. Louis area, so planning spring A/C and fall furnace visits around local weather is straightforward. Members receive priority scheduling and repair discounts, while one-time checks are a simple pay‑as‑you‑go option. A tech’s rule of thumb: pair a spring cool‑down and a fall heat‑up visit to catch minor issues before peak load. Final pricing is confirmed after we evaluate your specific system and any add‑ons you choose (accessories like humidifiers, etc.).

If you just want one-time maintenance. a $99 Clean & Check will get you a thorough examination and cleaning of one system (heating or cooling). The Preferred Partner Plan HVAC System Checks include an examination and cleaning of both the heating and cooling systems twice annually, along with discounts on repairs, service calls, and new equipment.

Schedule maintenance before extreme heat or cold to reduce breakdown risk and avoid seasonal rush delays.
