ROX Heating & Air - Littleton's Best HVAC Services

A common first step is to check your air filter—clogged filters are a frequent issue here and can severely restrict airflow, causing your system to work harder. If that's not the issue, our technicians are trained to diagnose everything from ignition problems to heat exchanger issues. We provide honest assessments and efficient repairs to restore your comfort quickly, using our extensive experience with all types of residential heating systems common in the Denver area.

A proper installation starts with expert design and sizing, which is critical for efficiency and comfort in our Colorado climate. Drawing on 15+ years of field experience, we assess your home's layout, insulation, and specific needs to recommend a correctly sized, high-efficiency furnace and air conditioner. Our team handles the entire installation with precision, ensuring your new system operates reliably and saves you money on energy bills for years to come.

This is often due to an issue with the reversing valve, a component that switches the system between heating and cooling modes. This specific problem is something we see regularly in the Littleton area. Our technicians are proficient in diagnosing and repairing reversing valve failures, as well as other common heat pump issues. We'll get your system properly heating your home again, ensuring it operates efficiently through our variable seasons.
