Question Answers

We use gas heat now. Does it make sense to switch to a heat pump in Windsor's climate?

Yes, a modern cold-climate heat pump is effective for Windsor, where winter lows rarely challenge its capacity. Switching from gas during peak electric hours from 4 PM to 9 PM can be managed with proper thermostat programming. The combined federal rebates and lower operational costs of a high-efficiency heat pump often result in long-term savings, making it a strategic upgrade especially with current incentives.

What permits and safety rules apply to a new AC installation in Windsor today?

All HVAC replacements in Windsor require a permit from the Town of Windsor Building and Planning Department. As of 2026, installations using A2L refrigerants like R-454B must follow strict new safety codes for leak detection and ventilation, as these refrigerants are mildly flammable. A licensed contractor will handle this permitting process and ensure the installation meets all current California Title 24 and EPA requirements.

Our Ecobee thermostat is showing an 'E1' alert. What should we do?

An Ecobee E1 error indicates a communication failure between the thermostat and the HVAC equipment. In Windsor, this can signal a wiring issue exacerbated by heat in the attic or a failing control board. First, check for a tripped breaker at the air handler. If the alert persists, a technician should inspect the low-voltage connections, as debris or a failing component in the condenser could be the root cause.

Our AC is from the 90s and runs constantly on hot days. Is it time for a replacement?

A system installed in the 1990s is now over 30 years old, which exceeds typical service life. In Windsor, this age makes the R-22 refrigerant unit highly inefficient and prone to breakdowns, particularly condenser fan motor burnout from seasonal grass and wildfire debris clogging the coils. Modern systems with R-454B refrigerant offer significantly better performance and reliability for homes originally built around 1945.

Why does our AC seem to struggle on afternoons when it's only 94 degrees out?

Local HVAC systems are designed for a 94°F outdoor temperature, which is the calculated design temp for Windsor. When ambient temperatures meet or exceed this limit, the system's capacity to remove heat diminishes, so it runs continuously to maintain setpoint. Modern R-454B refrigerant maintains better pressure and cooling capacity in these high-heat conditions compared to older refrigerants, improving performance at the design limit.

If our AC fails tonight during a heatwave, how quickly can a technician get to our home near the Windsor Town Green?

For a no-cool emergency near the Town Green, a technician can be dispatched from our office via US-101, typically arriving within 5 to 10 minutes. We prioritize these calls to prevent heat buildup in your home, which can strain an aging system and lead to compressor failure. Rapid response is key to diagnosing issues like a tripped breaker or a failed capacitor before secondary damage occurs.

Can our existing galvanized steel ducts handle a high-efficiency air filter for wildfire smoke and spring pollen?

Galvanized steel ductwork generally has the structural integrity to support a MERV-13 filter, which is effective for April pollen peaks and wildfire PM2.5. The critical factor is static pressure; an older blower motor may struggle, requiring a professional assessment to ensure proper airflow. We often recommend a system performance check before upgrading filtration to avoid reducing cooling capacity or causing motor strain.

What do the new 2026 SEER2 rules mean for us, and is there any financial help available?

The 2026 federal minimum is 14.3 SEER2, a standard that raises efficiency about 10% over previous models. Given PG&E rates near $0.38 per kWh, upgrading to a 16+ SEER2 unit can substantially reduce summer cooling costs. The Inflation Reduction Act provides rebates up to $8,000 for qualified heat pump installations, which often covers a major portion of the project cost when paired with local utility incentives.
