What Maintenance Agreement Members Get That One-Time Callers Don't
An annual AC service visit is a good decision. A maintenance agreement makes it automatic. D's Air & Heating maintenance agreement members get 15% off every covered service visit, plus priority scheduling — meaning when your system needs attention, you're not waiting behind a queue of emergency calls.
For homeowners who never want to think about whether they remembered to schedule service this year, the agreement handles it. You're on our list, your appointment gets set, and your equipment stays current on care. Lennox-authorized maintenance also supports your equipment warranty, so the service you're getting isn't just convenient — it's the right kind of service to protect what you've already invested in.
Most air conditioners don't fail without warning — they fail because the warning signs were never caught. A refrigerant level that's slightly low, a coil that's been accumulating dust for two seasons, a capacitor that's on its way out — none of these look like a problem until the temperature hits 95 and the system quits. Annual air conditioner maintenance in Chicago gives our EPA-certified technicians the chance to find those issues when they're still inexpensive to fix.
We recommend scheduling your AC tune-up once a year, ideally in the spring before cooling season starts. That single visit covers everything your system needs to perform reliably all summer:
- Inspection of refrigerant charge and leak check
- Cleaning of condenser and evaporator coils
- Lubrication of moving parts
- Electrical connection check and capacitor test
- Thermostat calibration and controls test
- Airflow and filter check
- Full system performance evaluation
One Visit a Year Is All It Takes to Keep Your AC Running Right
Is Annual AC Service Actually Worth the Cost?
The short answer: yes, and the math isn't complicated. A well-maintained air conditioner runs more efficiently, which means lower energy bills every month it operates. It also lasts longer — a system that receives consistent annual service routinely outperforms a neglected one by several years. When you factor in the cost of a premature replacement, skipping a tune-up to save money in the short term rarely works out ahead.
Maintenance agreement members reduce that cost further with 15% off every visit. For most households, the savings on a single repair call more than covers the cost of the agreement itself. That's before accounting for priority scheduling, which becomes genuinely valuable the first time you need same-week service in July.

Common Questions About AC Service in Chicago
How often should an air conditioner be serviced?
Once a year is the standard recommendation, and spring is the best time to do it. Getting your AC tuned up before the first hot stretch of the season means any issues are caught before they affect your comfort — not during a heat wave when every HVAC company in Chicago is fully booked.Once a year is the standard recommendation, and spring is the best time to do it.

One missed year isn't guaranteed to cause a failure, but it increases the odds. Refrigerant levels drift, coils accumulate buildup, and small electrical issues go undetected. Over two or three seasons without service, those small issues compound — and the repair bill that follows is almost always larger than several years of tune-ups combined.One missed year isn't guaranteed to cause a failure, but it increases the odds.
