Trusted HVAC Repair in Denver, CO 80260 - CMS Commercial Refrigeration Heating & Airconditioning

A furnace ignition failure in Denver is often due to a faulty igniter, flame sensor, or gas valve issue—common problems our technicians see daily. CMS offers prompt emergency service to diagnose the cause, get your heat running safely, and ensure your family stays warm. We prioritize these calls, especially during cold snaps, to provide fast, reliable repairs you can count on.

Frozen evaporator coils are typically caused by restricted airflow from a dirty filter, low refrigerant levels, or a failing blower motor—all issues exacerbated by Denver's dry climate and system strain. CMS technicians will thoroughly inspect your system, address the root cause (like recharging refrigerant or cleaning components), and provide maintenance tips to prevent future freezing and keep your cooling efficient.

For Denver's variable climate, we recommend bi-annual professional tune-ups: one in spring for your AC to prevent coil issues and one in fall for your furnace to check ignition components and safety controls. This proactive care from CMS helps catch small problems early, improves energy efficiency, and extends the life of your system, saving you from costly emergency repairs down the line.
