AC MAINTENANCE & TUNE-UPS IN LEWISVILLE, TX

A Koala-T AC tune-up starts at $89 per system (promotional price) with a regular price of $129. This includes our full 20-point inspection, cleaning, and testing protocol and applies to both air conditioning and heating systems. Our Joey Club members get the best deal: they receive both seasonal tune-ups included in their $160/year membership. DFW market pricing typically ranges from $80–$200 depending on the provider and what’s actually included.

Annual maintenance is recommended at a minimum for air conditioner systems in Texas, and this is required by most manufacturers to maintain warranty coverage. In North Texas, where your AC runs six to eight months per year under extreme heat and humidity, annual service is essential for catching a small issue or wear issue before it requires an expensive repair. ENERGY STAR and every major manufacturer (Amana, Trane, Carrier, Lennox) recommend pre-season professional maintenance.

Our 20-point AC tune-up is delivered by our experienced technicians and includes thermostat calibration, refrigerant pressure testing with superheat/subcooling measurements, electrical connection inspection, capacitor and contactor testing, condenser and evaporator coil cleaning, condensate drain flushing, filter replacement, static pressure measurement, full system cycle test, and safety checks. We'll then present our findings to you and, if necessary, recommend air conditioner repair work or even a new system installation, depending on the issues we find.

Yes, annual AC maintenance is genuinely necessary in North Texas. Aside from keeping your AC unit cooling properly, your manufacturer requires it to keep your warranty valid. The Department of Energy confirms that proper maintenance reduces energy consumption and extends equipment life. And 75–80% of summer emergency calls we see involve issues that a tune-up would have caught. We document every finding and never recommend work you don’t need, hence why we put our pricing on our website instead of hiding behind ‘call for a quote.’

Some AC maintenance tasks are absolutely homeowner-friendly: changing your air filter every 30–60 days, keeping the outdoor unit clear of debris, and rinsing the condenser with a garden hose. But testing refrigerant levels, measuring electrical components, cleaning the sealed evaporator coil, and verifying system performance require professional tools and a TDLR-issued TACL license. In Texas, it’s actually illegal to work on refrigerant lines without EPA 608 certification.

March through April is typically the best time to schedule an air conditioning tune-up in the DFW area, before the heat arrives and before everyone else is calling for emergency repairs. Scheduling a service call in spring means you'll get easier appointment availability and time to address any issues found before summer demand drives up parts and labor wait times, with a much lower risk of being without AC during a heatwave. It just makes sense.

If we find something wrong during your AC tune-up, we'll show you exactly what we found, explain what it means in plain English, and give you a written quote before any additional work begins. You decide whether to proceed, with no pressure and no surprise charges, as outlined under our No-Sweat Pricing™ guarantee. If you choose to move forward with the repair, we'll waive your diagnostic fee.

Our thorough 20-point AC tune-up typically takes 45 minutes to 1 hour for a standard residential system. If we find issues that require additional diagnosis or if your system has dual zones or multiple air handlers, it may take slightly longer. We’ll always let you know the expected time when we arrive.
