Cooling system tune-up

You rely on your AC system for home comfort. The last thing you want is for the AC to break down on a hot summer day. The best way to keep your AC system from shutting down is to set up regular tune-ups.

If you are already one of our Annual Plan Customers you know that we send you a reminder about scheduling this service each year.

A well-maintained HVAC system is far less likely to breakdown under the stress of extreme temperatures. Our technicians follow the checklist below for every spring tune-up to ensure that your AC is ramped up and ready for a Texas heat wave. We’ll let you know if you’re likely to need any repairs based on the age of the system as well as wear and tear on parts that can be observed during a spring air conditioning tune-up. There’s never a convenient time in the summer to be dealing with a broken AC unit. A regular visit from your Markorair HVAC technician is the best way to keep your air conditioning system in tip-top shape and ready for a humid summer in east Texas.

Our HVAC technicians are factory trained to repair, maintain or replace any make or model air conditioner. After factory certification, each of our HVAC technicians participates in ongoing training provided by Markorair. Your HVAC system is your largest appliance and a major investment.

Let the pros at Air Specialist extend the life of your heating and cooling system and keep energy bills in check through regular maintenance. Whether you are an annual plan customer or just want to have a spring tune-up, know what to expect with the Cooling Checklist.
