FAQs
My Ecobee thermostat is showing an 'E4' alert. What does that mean?
An Ecobee E4 code indicates the thermostat has lost communication with the outdoor unit. In our climate, this is commonly caused by voltage fluctuations from extreme temperature swings tripping a safety lockout, or a failing control board in an older condenser. It's a signal to have the low-voltage wiring and safety controls inspected before the problem escalates to a complete system shutdown.
Why does my AC struggle when it gets above 90 degrees?
Most systems in Missoula are designed for a 90°F outdoor temperature, per local code. When temperatures exceed that during a heatwave, the system's capacity drops and it runs continuously. Modern units using R-454B refrigerant maintain better efficiency and capacity at these higher temperatures than the old R-22 systems, but they still have a physical performance limit based on that original design temperature.
What if my AC quits on a hot day near Fort Missoula Regional Park?
A sudden 'No-Cool' event requires checking the thermostat, circuit breaker, and air filter first. For Orchard Homes residents, our service vans are staged to use US-93 for direct access, ensuring a technician can typically be on-site within 15 to 20 minutes of your call to diagnose critical failures like a locked compressor or a complete refrigerant leak.
Are new air conditioners more efficient now, and is there a rebate?
Yes, federal law now mandates a minimum of 13.4 SEER2 for new units, a significant jump from older models. With NorthWestern Energy's local rate at $0.13/kWh, upgrading can cut cooling costs noticeably. The active Inflation Reduction Act rebates provide up to $8,000 for a qualifying heat pump installation, which often makes the higher efficiency equipment cost-neutral after incentives.
Should I switch from my gas furnace to a heat pump in Orchard Homes?
Given our cold winters, a properly sized cold-climate heat pump is now a viable primary system. The economics are favorable when combining the $8,000 federal rebate with NorthWestern Energy's high-efficiency incentives. To manage costs, you can set the system to minimize use during peak hours (5 PM to 9 PM) and keep the gas furnace as a backup for the most extreme below-zero nights, ensuring reliability and lower operating costs.
What should I know about permits and safety for a new AC installation?
All new installations in Missoula County require a permit from the Building Division. Since 2025, systems using A2L refrigerants like R-454B have mandated safety standards, including leak detectors and specific tubing practices. Hiring a licensed contractor ensures the installation meets these 2026 codes for safe operation and validates your eligibility for the significant federal and utility rebates.
How long do HVAC systems typically last in Orchard Homes?
The average HVAC system in a 1976-built Orchard Homes house is now 50 years old. At this age, the original galvanized steel ductwork and refrigerant lines are often fatigued. This makes the system highly prone to frozen evaporator coils, especially during our rapid spring temperature swings when the system tries to switch from heating to cooling before the refrigerant charge is properly balanced.
Can my home's duct system handle better air filters for wildfire smoke and pollen?
Your existing galvanized steel ducts are robust, but adding a high-MERV filter for May pollen and wildfire PM2.5 requires caution. We must measure static pressure; a MERV-13 filter in a 50-year-old system can often cause airflow restriction, leading to frozen coils. A proper assessment might recommend sealing the existing ducts or adding a dedicated air purifier to avoid overtaxing the HVAC blower.
