Frequently Asked Questions About Grimes HVAC Service

If your AC isn't cooling, is low on refrigerant, making strange noises, or leaking water, it needs repair. Don't ignore these problems — they get worse over time. Call us and we'll diagnose the issue. Many problems can be fixed without full replacement.

In winter, set it as low as you're comfortable (68°F is typical). In summer, set it as high as comfortable (78°F or higher). Programmable or smart thermostats save money by adjusting temperature when you're away or sleeping. We can help you choose the right thermostat for your home.

Furnaces burn gas to create heat, so safety is critical. Annual inspection checks for gas leaks, proper venting, safe burner operation, and electrical connections. Regular inspection prevents dangerous carbon monoxide leaks and ensures your furnace runs efficiently and reliably.

Yes. Check your filter monthly and replace it every 1–3 months depending on use and home conditions. A clean filter keeps your system running efficiently and improves air quality. Some filters are washable; most are disposable. We can show you the right type for your system.

Repair fixes a specific problem — a broken compressor, bad thermostat, or refrigerant leak. Replacement means installing a new system. We recommend repair if your equipment is younger and the cost is reasonable. For older systems with frequent problems, replacement makes sense.

A properly sized system keeps your home comfortable without excessive cycling. Oversized systems waste energy; undersized systems can't keep up. We perform load calculations to determine the right size for your home. If you're unsure about your current system, we can evaluate it.

We're a Tempstar Elite Dealer and install Tempstar and LG systems. We also service Carrier, Trane, Lennox, York, Rheem, and other major brands. Quality and reliability guide our recommendations.

Yes. Programmable and smart thermostats can save 10–15% on heating and cooling costs through scheduling and setback features. Remote control via smartphone adds convenience. The savings often pay for the thermostat within a couple of years.
