Question Answers
What's included in your HVAC maintenance service?
Our maintenance service is designed to keep your system running efficiently and help prevent common Concord issues like dirty evaporator coils. We perform a comprehensive check, including cleaning key components, inspecting electrical connections, testing system controls, and checking refrigerant levels. Regular maintenance can improve performance, extend your system's lifespan, and often catch small problems before they lead to a major repair.
My AC unit turns on and off frequently (short cycles). What causes this in Concord homes?
Short cycling is a common issue we see in the area, often caused by an oversized unit, a dirty air filter, low refrigerant, or a faulty thermostat. It puts extra strain on your system and reduces efficiency. Our technicians are familiar with diagnosing the root cause specific to local home setups. We'll perform a thorough inspection to identify the problem—whether it's a simple fix like cleaning the coils or a more involved repair—to restore proper, energy-efficient operation.
How does your warranty work on a new installation?
We stand behind our installations and replacements with confidence. All our work is backed by a written 365-day warranty on labor. This means if any issue arises related to our installation within a year, we'll return to fix it at no additional cost to you. We provide this warranty for your peace of mind, ensuring your new AC or heater system performs as promised for your Concord home.
