Frequently Asked Questions
Why does our AC seem to struggle on the hottest summer days?
Your system is engineered for a 78°F design temperature, which is the local outdoor temperature it is sized to maintain 75°F indoors. On days that exceed this, which is common, the system must run continuously. Modern units using the new R-454B refrigerant maintain better efficiency and capacity at these higher temperatures compared to older R-410A systems, reducing the performance gap you may be experiencing.
Is it worth upgrading our old unit to meet the new 2026 efficiency standards?
The federal minimum standard is now 14.3 SEER2. A new system meeting this will use significantly less electricity than a unit from the 1990s. With Xcel Energy rates at $0.15 per kWh, the operational savings are tangible. The Inflation Reduction Act provides rebates of up to $8,000 for qualifying heat pump installations, which can dramatically offset the upgrade cost and improve your home's value.
We use propane heat. Should we consider switching to a heat pump in Keystone?
For many homes, a cold-climate heat pump is a viable primary heat source. Modern models are effective at our winter lows, especially when paired with your existing propane system as a backup. Operating the heat pump during off-peak hours, outside the 2 PM to 7 PM utility window, maximizes savings. The federal rebate of up to $8,000 makes this transition from propane financially attractive for long-term owners.
Our AC just stopped on a hot day in River Run Village. How fast can a technician get here?
For a no-cool emergency, our dispatch from the Keystone Resort Base Area uses US-6 for direct access to your neighborhood. This routing typically results in a technician arriving within 5 to 10 minutes. We prioritize these calls to prevent compressor damage and restore comfort quickly during peak afternoon hours.
Can we improve our indoor air with the wildfire smoke and summer pollen?
Yes, addressing Keystone's wildfire PM2.5 and June pollen peak is crucial for indoor air quality. We recommend upgrading to a MERV-13 air filter, which captures these fine particulates. Your existing galvanized steel ductwork is typically robust enough to handle the increased static pressure from a higher-MERV filter, but we should verify this with a quick static pressure test during a service visit.
Our Ecobee thermostat is showing an E1 alert. What does this mean?
An Ecobee E1 alert indicates the thermostat has lost communication with your HVAC equipment. In Keystone, this is often caused by a safety switch tripping due to a frozen condensate line—a frequent issue in our dry climate. It can also signal a blown low-voltage fuse from a failing component. This alert allows for proactive service before a complete system failure occurs.
Our air conditioner is from the original build. Should we be worried about its age?
An average home in Keystone was built in 1987, meaning the original HVAC unit could be nearly 40 years old. Systems this old in our climate often develop frozen condensate lines. The arid air causes condensate to evaporate quickly, allowing dust and rust from the galvanized steel ductwork to accumulate and block the drain pan. This is a common failure point that can lead to water damage and reduced efficiency.
What are the permit and safety requirements for a new AC installation in 2026?
All installations require a permit from the Summit County Building Inspection Department. Since January 2023, new residential systems must use lower-GWP A2L refrigerants like R-454B. These are mildly flammable, so 2026 codes mandate specific leak detectors, updated service procedures, and special technician certifications. We handle all permit paperwork and ensure the installation meets these updated safety standards.
