Questions and Answers
Can my home's duct system handle better filters for our wildfire smoke and June pollen?
Upgrading filtration is wise for Glasgow's wildfire PM2.5 and peak pollen, but your existing galvanized steel ductwork requires assessment. While durable, these older ducts must be checked for leaks and adequate return air size before installing a MERV-13 filter. A high-efficiency filter can create excessive static pressure in a restrictive system, reducing airflow and causing the evaporator coil to freeze. A technician should measure your system's static pressure to confirm it can support the filter upgrade without harming performance.
What should I know about permits and safety for a new AC installation in 2026?
All HVAC replacements in Valley County require a permit from the Valley County Building Department, which ensures compliance with current mechanical and electrical codes. For 2026, this includes strict new standards for installations using A2L refrigerants like R-454B, which are mildly flammable. These rules mandate specific leak detection systems, updated service port locations, and specialized technician certification. Proper permitting protects your home insurance and ensures the system is installed to the latest safety protocols for its entire lifespan.
My Ecobee thermostat is showing an 'E1' alert. What does that mean for my system?
An Ecobee E1 alert indicates the thermostat is not detecting a call for cooling or heating from your HVAC equipment. In Glasgow, this often points to a safety lockout on the system's control board, frequently triggered by a pressure switch or flame sensor fault. Given our arid climate and large temperature swings, it can also signal a failed capacitor or a disruption in the 24-volt control circuit. This alert allows for proactive diagnosis before a complete system failure occurs during peak demand.
With natural gas heat, should I consider switching to a heat pump in Glasgow?
A modern cold-climate heat pump is a viable primary heating system for Glasgow, even with our sub-zero winter lows. The technology now provides reliable heat down to -15°F. To maximize savings, pair it with your existing gas furnace as a dual-fuel system; the heat pump handles heating during milder weather and MDU's off-peak hours, while the furnace takes over during extreme cold and the 4 PM to 9 PM utility peak period. This strategy optimizes comfort while leveraging the lower operating cost of the heat pump for most of the heating season.
Why does my AC struggle when it's over 95°F, even though it's supposed to work up to 88°F?
Air conditioners in Glasgow are sized for a design temperature of 88°F, based on local historical data. On days reaching the mid-90s, the system operates continuously to try to close that 7+ degree gap, which is its design limit. Modern systems using the new R-454B refrigerant maintain better capacity and efficiency at these higher temperatures compared to older R-22 units. Proper sizing from a Manual J load calculation is critical to ensure minimal struggle during our hottest afternoons.
If my AC fails during a heatwave, how fast can a technician get to my house near Glasgow City Park?
For a no-cool emergency near City Park, our dispatch uses US-2 for direct access, ensuring a technician can typically be on-site within 5 to 10 minutes. We prioritize these calls to prevent heat stress and protect sensitive electronics in the home. Once there, we can quickly diagnose common issues like a tripped breaker or a failed capacitor to restore cooling. For more complex repairs, we provide a clear timeline and temporary solutions if needed.
My Glasgow home's AC unit seems original. How long do systems typically last here?
Homes in Downtown Glasgow from the 1960s often have systems at or past their 20-year service life. A unit installed in 1962 would now be 64 years old, which is well beyond the typical lifespan. These older systems are particularly prone to frozen evaporator coils because their refrigerant charge and airflow often can't manage the extreme temperature differentials between our arid summer heat and a conditioned 72°F home. Age-related wear on electrical components and galvanized steel ductwork leaks also contribute to frequent failures.
Is the new 13.4 SEER2 minimum efficiency standard worth the investment with current electric rates?
The 2026 SEER2 standard creates a significant efficiency floor, with new systems using far less energy than the older units common in Glasgow. At MDU's rate of $0.11 per kWh, upgrading from an 8 SEER unit to a 16 SEER2 model can cut cooling costs by nearly half. The active federal HEEHRA rebates, capped at $8,000, directly offset the higher upfront cost of these advanced systems. When combined with the $500 MDU Energy Efficiency Program rebate, the net investment often pays back through utility savings in just a few seasons.
