Why is my AC running but not cooling?

Common causes: dirty air filter restricting airflow (check first — free fix), frozen evaporator coil from restricted airflow or low refrigerant, failed capacitor, or dirty condenser coils. A technician with gauges and electrical test equipment diagnoses the actual cause quickly.

How much does AC repair cost?

Minor repairs (capacitor, contactor): $150–$400. Refrigerant recharge with leak repair: $300–$1,500. Evaporator coil: $800–$2,500. Compressor: $1,200–$2,800. Full system: $5,000–$12,000.

Can I add refrigerant to my AC myself?

No — EPA 608 certification is legally required to purchase and handle refrigerants. DIY refrigerant addition without fixing the leak is ineffective. A licensed technician must find and repair the leak before recharging.

How often should AC refrigerant be recharged?

Never — a properly operating AC system is a closed loop and should never need refrigerant unless there's a leak. Annual 'top-off' recommendations are a red flag; the leak must be found and fixed.

What Is AC Repair Services?

Air conditioner repair addresses the full range of cooling system failures — from capacitor failures and refrigerant leaks to compressor issues — restoring comfort quickly and correctly.

Most Common AC Problems

Capacitor failure ($150–$400): the single most common AC repair, especially after summer heat stress — capacitors start compressors and fan motors. Refrigerant leak ($300–$1,500): low refrigerant means poor cooling and eventual compressor damage. Contactor failure ($150–$350): the electrical switch controlling the outdoor unit. Compressor failure ($1,200–$2,800): most expensive repair — sometimes replacement pencils out better.

Diagnosis

A licensed technician checks: refrigerant pressure with manifold gauges, electrical components, condensate drain, airflow, and compressor operation. Many homeowners misdiagnose 'not cooling' as refrigerant when the actual cause is a clogged filter, dirty coil, or capacitor.

Repair vs. Replace

The 5,000 rule: if repair cost times system age exceeds $5,000, replacement often makes more sense. A system over 12–15 years old, using R-22 refrigerant, or with multiple failures in two years favors replacement.

Emergency Service

AC failure in extreme heat is a health emergency for vulnerable populations. Most licensed contractors offer emergency service — typically $75–$150 after-hours surcharge. Maintenance agreements often include priority emergency scheduling without the surcharge.

What to Look for in a HVAC Provider

State HVAC contractor license (required in most states) and EPA 608 certification for refrigerant handling
NATE (North American Technician Excellence) certification — the industry's highest technical standard
Experience with your specific equipment brand (ask about their top manufacturer relationships)
Transparent flat-rate or hourly pricing disclosed before the technician arrives
Manufacturer-authorized for warranty repairs on your brand
Maintenance plan options that include priority emergency scheduling
