HVAC Company in Norman, OK
HVAC systems fail at the worst possible times, usually middle of July heatwaves or January cold snaps when repair companies are swamped with emergency calls.
Regular maintenance prevents most catastrophic failures, but few homeowners schedule tune-ups until something stops working. Filters clog, refrigerant levels drop, electrical connections loosen, and minor issues compound into expensive replacements that proper servicing would have caught early.
Installation quality matters more than the equipment brand in many cases. A premium system installed poorly performs worse than a mid-range unit installed correctly. Ductwork sizing, refrigerant charging, and airflow balancing require precision that separates competent technicians from those just going through motions.
Energy efficiency ratings look impressive on spec sheets but don't always translate to real-world savings. Your home's insulation, ductwork condition, and thermostat programming affect actual performance more than SEER ratings alone. Top-rated HVAC companies in Norman, OK, assess your entire system rather than just selling you the highest-rated equipment.
Sizing calculations determine whether your system can heat or cool your space effectively. Oversized units cycle on and off frequently, wasting energy and failing to dehumidify properly. Undersized systems run constantly without reaching desired temperatures, burning out components prematurely from overwork.
Warranty coverage varies dramatically between manufacturers and contractors. Some parts' warranties last ten years, while labor might only be covered for one. Extended service agreements add costs but provide predictable budgeting for repairs that inevitably arise.
Your AC dying during Oklahoma's brutal summer heat means days of misery waiting for overbooked contractors to squeeze you in. At Drennen Mechanical Inc., we've spent 15 years keeping homes comfortable through extreme weather with reliable service and honest recommendations.
