FAQs
Why does our AC struggle when it hits the mid-90s?
Metro area systems are engineered for an 88°F design temperature, based on historical data. When temperatures exceed that, the system runs continuously to try to maintain a setpoint, reducing its capacity to dehumidify. Modern units using R-454B refrigerant maintain better efficiency and pressure stability in these higher temperature extremes compared to older R-410A systems.
Our Ecobee thermostat is showing an E1 error. What's wrong?
An Ecobee E1 alert indicates the thermostat is not detecting voltage from your HVAC equipment, often due to a safety lockout. In our climate, this frequently points to a frozen evaporator coil or a tripped high-pressure switch from a dirty filter or low refrigerant charge. It's a protective signal to prevent compressor damage, and a technician should diagnose the root cause to resolve the lockout condition.
Can we use better filters for wildfire smoke and spring allergies?
Yes, addressing PM2.5 from wildfires and May pollen peaks requires MERV-13 filtration. However, the existing galvanized steel ductwork in many Falcon Heights homes was not designed for such high static pressure. A technician must perform a static pressure test before installation; often, sealing leaky ducts or modifying the return air system is necessary to accommodate these filters without straining the blower motor.
What should we verify about permits and refrigerant for a new install?
All HVAC replacements in Falcon Heights require a permit from the City of Falcon Heights Building Department. As of 2026, new systems predominantly use A2L refrigerants like R-454B, which are mildly flammable. This mandates compliance with updated safety standards (like UL 60335-2-40), requiring specific leak detectors, updated electrical codes, and proper labeling that a standard R-410A install would not. Your contractor must pull the permit and follow these protocols.
We have gas heat. Should we consider a heat pump?
For Falcon Heights, a cold-climate heat pump is a viable primary heat source, even with winter lows near -10°F. The economics are strengthened by pairing it with your existing gas furnace as a dual-fuel system. During Xcel's peak hours (2 PM to 8 PM), the heat pump provides efficient heating, and the furnace automatically takes over during extreme cold, optimizing for both comfort and operating cost.
What does the new SEER2 rating mean for my replacement cost?
The 2026 federal minimum is 13.4 SEER2, a new testing standard that better reflects real-world performance. While a higher-SEER2 unit has a higher upfront cost, the Inflation Reduction Act's HEEHRA rebates can provide up to $8,000 off qualified heat pump installations. At Xcel Energy's $0.14/kWh rate, the operational savings from a modern system often justify the upgrade, especially with the rebate.
Our furnace is from the 90s. Is it really time for a new one?
Systems from that era in Falcon Heights are now 30+ years old. The galvanized steel ductwork and components are beyond their design lifespan. This age directly contributes to the most common service call here: condensate line freezing and clogging. As seals degrade and insulation fails, moisture management fails, leading to blockages and potential water damage during our humid summers.
Our AC just quit on a hot day. How fast can someone get here?
For a no-cool emergency in Falcon Heights Central, dispatch from our shop near the University of Minnesota St. Paul Campus puts us on MN-36 within minutes. Typical on-site response is 10 to 15 minutes. The first step is to check your circuit breaker and the outdoor unit's disconnect switch, as these simple resets resolve many immediate calls.
