Routine AC Tune-Ups

If your air conditioner isn’t keeping up with the summer heat, it might not be a sign of failure—it could simply be time for a tune-up. Skipping regular maintenance can lead to decreased efficiency, higher utility bills, and unexpected breakdowns, especially during peak usage.

Common issues we address during maintenance include:

• Dirty or clogged air filters

• Low refrigerant levels

• Thermostat calibration issues

• Condenser and evaporator coil buildup

• Faulty electrical connections

• Clogged drain lines

• Worn belts or bearings

• Airflow obstructions

Glenmont Heating & Air can help. Our technicians use the latest tools to diagnose system performance, clean and inspect key components, and make small adjustments before they turn into big repairs. With a fully stocked inventory of parts and a commitment to same-day service whenever possible, we ensure your system is running at full capacity when you need it most.

Quality AC Products & Components

We don’t just service your system—we help it perform better with high-quality parts and materials that support long-term reliability.

Our Filter & Coil Services

Clean filters and coils are essential to AC performance. Here’s what we focus on:

• High-Efficiency Air Filters – Capture allergens, dust, and debris to improve indoor air quality.

• Condenser Coil Cleaning – Ensures heat is released efficiently to keep your unit from overworking.

• Evaporator Coil Maintenance – Prevents frost buildup and ensures cool air delivery.

• UV Light Integration – Helps sanitize your system and eliminate mold or bacteria buildup.

Our Thermostat & Control Calibration

We also inspect and optimize your thermostat and system controls to ensure your AC responds quickly and accurately to changes in temperature settings. This helps improve comfort and energy efficiency across your entire home or office.

Our Preventive Maintenance Parts

During routine service, we inspect and often replace small components that play a big role in performance:

• Capacitors – Regulate voltage and keep the motor running smoothly.

• Contactors – Control the flow of electricity and prevent system malfunctions.

• Belts – Drive fan motors and compressors for proper airflow.

• Drain Line Treatments – Keep condensation flowing out to prevent water damage and mold.

Ductwork and Indoor Air Quality Solutions

Your air conditioner is only as good as your ductwork. That’s why we offer duct inspections and sealing services to prevent air loss and improve distribution. We also offer indoor air quality solutions, including air purifiers, dehumidifiers, and smart thermostats, to help you get the most out of your AC maintenance services.
