Frequently asked questions

Colfax HVAC Denver focuses on residential heating, cooling, ventilation, and indoor air quality services, including repair, installation, maintenance, and diagnostics for furnaces, air conditioners, heat pumps, and related systems.

An air conditioner should be inspected if it stops cooling, blows warm air, short cycles, makes unusual sounds, or if it has been more than a year since the last maintenance visit. Scheduling a tune-up before summer can help prevent mid-season failures.

Common signs include a furnace that won't start, blows cold air, lights and then shuts off, makes unusual sounds, or causes a sudden rise in heating costs. Any of these warrant an inspection, especially before cold weather arrives.

Most homes benefit from a filter change every one to three months, with more frequent changes during heavy-use seasons or in homes with pets. A technician can recommend a schedule based on your system and filter type.

Filtration, ventilation, humidity, ductwork condition, and outdoor pollutants all affect indoor air quality. Tightly sealed, energy-efficient homes can trap pollutants if not properly ventilated.

Repair fixes a specific failed component to restore operation, while replacement swaps aging or unreliable equipment for a new system. Replacement is often considered when a system is near the end of its service life or repairs become frequent.

Regular maintenance helps a system run efficiently, can extend equipment life, and may catch small issues before they become major failures. Seasonal tune-ups support reliable performance through both heating and cooling seasons.
