Repairs and Servicing
Are you ready to have your air conditioner serviced? We're here to keep you cool and comfortable all summer long. Our team of trained technicians is ready to assist you with any issues you may be experiencing.

A thermostat doesn’t simply take your input about how to manage air conditioning in your home — it’s also the brains of your HVAC system and plays a critical role in making sure it operates properly. What could seem like an issue with your air conditioning unit(s) could actually be an issue with your thermostat.
By the way, all customers who buy or rent an A/C system through Sterling receive a free smart thermostat.
Air conditioning leak repair involves identifying and fixing any breaches in the system that may be causing the loss of refrigerant. Refrigerant replacement involves evacuating the system of any remaining refrigerant and then charging it with new refrigerant. Both leak repair and refrigerant replacement are important for maintaining the efficiency and performance of the air conditioning system. If the system is low on refrigerant, it may not be able to cool the air effectively, and a leak can cause the system to run less efficiently, even potentially causing damage. Don't wait to have these issues addressed.
Electrical control system repair and replacement involves fixing or replacing any malfunctioning components. This can include the thermostat, control board, and wiring. Electrical control system issues can cause the air conditioner to not function properly or stop working entirely. Repairing or replacing faulty electrical components can help restore the system's performance and ensure that it's operating optimally.
The contactor and capacitor are important electrical components in the air conditioning system. The contactor is a switch that turns the system on and off, while the capacitor stores electrical energy and helps the system start and run. If either of these components is damaged or not functioning properly, it can cause the air conditioner to stop working or not function efficiently. Repairing or replacing the contactor and capacitor can help restore the system's performance and make sure it's operating at full potential.
Air conditioning drainage clearing & repair involves clearing any blockages in the drainage system and fixing any damage they may have caused. The drainage system is responsible for removing excess moisture from the air conditioner. Clearing blockages and repairing the drainage system can help prevent water damage and ensure that the air conditioner is operating effectively.
In situations of intense heat or in buildings and homes that require more intense air conditioning through the summer months, Sterling technicians are prepared to respond quickly to immediately diagnose and attempt repair of a failing A/C system.
We carry, install, and service all major makes and models.
