Seasonal Maintenance & Protection Schedules
HVAC systems lose approximately 5% operating efficiency each year maintenance is neglected. Regular bi-annual tune-ups prevent 90% of catastrophic emergency breakdowns, maintain manufacturer warranties, and lower monthly utility bills.
Spring AC Tune-Up
Schedule: March – May- Chemical wash and fin straightening on outdoor condenser coils.
- Digital manifold measurement of refrigerant subcooling and superheat.
- Capacitance test (μF) on dual-run motor and compressor start capacitors.
- Condensate drain line flush, vacuum, and float safety switch test.
- Blower motor amperage verification and evaporator coil static pressure drop.
Fall Heating Safety Check
Schedule: September – November- Heat exchanger optical camera & combustion analyzer check for hairline cracks.
- Flame sensor microamp signal test and burner assembly cleaning.
- Hot surface ignitor electrical resistance (Ω) and draft inducer motor test.
- Gas valve manifold pressure check (3.5 in. w.c. natural gas standard).
- High-limit temperature safety switch and flue draft pressure switch calibration.
Filter Replacement Cadence by Media Type
Matching your filter replacement frequency with household occupancy and filter MERV ratings.
Every 30 Days
MERV 1–4. Captures only large dust particles to protect blower wheel. Minimal allergen protection.
Every 60–90 Days
MERV 8–11. Residential sweet spot for dust, pollen, and pet dander with low static pressure drop.
Every 6–12 Months
MERV 13–16. Captures viral droplets, PM2.5 smoke, and fine allergens with massive dust-holding capacity.
Should You Repair, Replace, or Upgrade Your HVAC System?
HVAC decisions aren't binary. A failing 12-year-old system competes against both a targeted repair and a high-SEER2 inverter heat pump that pays for itself in reduced monthly electric bills.
Targeted Component Repair
Best when the system is relatively young (under 8–10 years) and the mechanical failure is isolated.
Like-for-Like Replacement
Best when the system is 12–15+ years old and faces a major component failure (evaporator coil or compressor).
High-Efficiency Heat Pump Upgrade
Variable-speed inverter system (18–22+ SEER2) maximizing energy savings and tax credit incentives.
