Monthly filter changes and seasonal cleaning ensure optimal performance. Professional maintenance includes refrigerant checks, coil cleaning, and system calibration.
Yes, refrigerant handling requires EPA certification and electrical work needs permits. Professional installation ensures safety, warranty coverage, and optimal performance.
Unit size depends on home square footage, insulation, and climate. A 2,000 sq ft home typically needs 3-4 tons. Oversizing wastes energy and reduces humidity control.
Central air conditioning system cost ranges $3,500-$7,500 for homes with existing ductwork. Complete installations with new ducts cost $8,000-$15,000 including permits and labor.
Central air conditioning for apartments requires landlord approval and existing ductwork. Mini-split systems offer an alternative for apartments without ducts.
The best central heating and air conditioning system combines high SEER ratings (16 ), variable-speed technology, and proper sizing. Top brands include Carrier, Trane, and Lennox.
Central air conditioning service should occur annually before cooling season. Find "central air conditioning repair near me" for tune-ups, filter changes, and refrigerant checks.
Yes, central air conditioning systems filter air through the return ducts. Upgrade to HEPA or electronic filters for improved indoor air quality and allergen removal.
Expert Tip: ENERGY STAR systems with 16 SEER qualify for federal tax credits up to $300 plus utility rebates of $200-$1,000.
