We suggest servicing your AC twice a year in Arizona due to the extreme heat. Routine maintenance enhances efficiency, prevents breakdowns, and prolongs the lifespan of your system.

Common signs of issues include warm air, weak airflow, unusual noises, leaks, high energy bills, or frequent cycling. If you notice any of these signs, please contact us for assistance.

This often results from low refrigerant levels, dirty filters, thermostat malfunctions, or electrical issues. Contact us to diagnose and repair the problem quickly.

The cost depends on system size and efficiency. Most replacements typically range from $7,000 to $15,000 or more, excluding ductwork. Contact us for a free estimate.

Most systems last 10 to 15 years with proper maintenance. The Arizona heat can shorten their lifespan without regular tune-ups — you can book yours with us online today or give us a call!

Choosing the right system size depends on your home’s square footage, insulation, and layout. Mid-State Refrigeration can perform a load calculation to ensure you select the correct size. Contact us for assistance.

If your system is older than 10 years or frequently breaks down, replacing it may be more cost-effective. Call us, and we can help you decide.

Warning signs include uneven heating, unusual odors, high bills, frequent cycling, or a system over 15 years old. Call us to inspect your unit.

In Arizona, it is advisable to change your AC filter monthly because of the high dust levels in the state. Contact us if you need a new filter or assistance with the replacement.

We do install customer-supplied thermostats and HVAC equipment, but this is done on a case-by-case basis. Please note that since we did not supply the product, we cannot provide a warranty for the equipment itself.

While our workmanship is guaranteed, the customer is responsible for any product defects, compatibility issues, or manufacturer warranty claims. If you have any questions, please feel free to contact us.
