High-MERV filters combat both pollen particles and fine PM2.5. Your existing galvanized sheet metal ductwork is generally robust, but adding a MERV-13 filter can increase static pressure. A technician should measure your system's static pressure and fan capacity to ensure it can handle the added restriction without reducing airflow or causing coil freeze-ups.

Systems in Farmington homes from the mid-1950s are now over 70 years old. With age, refrigerant charge can drift and airflows degrade. This, combined with our high humidity profile, directly leads to the most common failure we see: frozen evaporator coils. The coil temperature drops too low when airflow is restricted, causing moisture to freeze and block heat exchange entirely.

A dispatch from our shop near Nemacolin Woodlands Resort puts us directly on US-40 for a straight shot into your neighborhood. For a no-cool emergency in Farmington, our standard response window is 15 to 20 minutes. We prioritize these calls to prevent heat buildup and potential humidity damage inside the home.

Modern cold-climate heat pumps operate efficiently in Farmington's winter lows. Pairing one with your existing propane furnace as a backup creates a dual-fuel system. This setup automatically uses the most cost-effective fuel source based on outdoor temperature and utility rates. You can program it to avoid operation during West Penn Power's peak hours from 2 PM to 7 PM to maximize savings.

HVAC systems are sized for a design temperature, which in Farmington is 86°F. When outdoor temperatures exceed this—which they often do in summer—the system must run longer to maintain setpoint. Modern units using R-454B refrigerant maintain better capacity and efficiency in this high heat compared to older R-22 systems, but extended run times on the hottest days are expected.

As of 2026, the minimum SEER2 rating is 14.3 for systems like yours. Upgrading to a modern 16+ SEER2 unit can cut cooling energy use by 15-20%. At Farmington's current rate of $0.14 per kWh, that's meaningful savings. The active Inflation Reduction Act rebates, capped at $8,000, can significantly offset the upgrade cost, improving your payback period.

All installations require a permit from Fayette County Building Code Enforcement. Since 2026, new systems must use A2L refrigerants like R-454B, which are mildly flammable. This mandates specific safety standards: leak detection systems, service valves, and tools rated for flammable refrigerants. Only EPA Section 608 certified technicians holding a Type III certification can legally handle these refrigerants.

An Ecobee E1 alert signals the thermostat has lost communication with your HVAC equipment. In Farmington, this often points to a control board failure, a blown low-voltage fuse, or a safety lockout due to a fault like a frozen coil. It requires a technician to diagnose the root cause, as the system will not operate normally until the communication loop is restored.
