Our licensed and insured HVAC technicians deliver dependable air conditioning repair, installation, and maintenance with genuine local care throughout Multnomah and Polk counties.

Our Air Conditioning Repair Services

When the summer heat rises, a reliable cooling system makes all the difference. Our air conditioning repair services cover everything from sudden breakdowns to subtle efficiency issues that drive up your energy bills.

The Most Common AC Problems We Fix

  • Burnt or Failing Capacitors: When capacitors wear out, your AC unit may struggle to start or fail mid-cycle. We replace damaged components to restore consistent operation and protect the compressor.
  • Refrigerant Leaks: Loss of refrigerant causes poor cooling, ice buildup on coils, and higher electricity use. We locate and seal leaks, recharge your system, and test for lasting performance.
  • Electrical Failures and Wiring Damage: Frayed wiring or faulty circuit boards can shut down the entire air conditioning system. Our licensed electricians repair connections safely and verify system grounding for reliability.
  • Frozen Evaporator Coils or Drain Line Backups: Low refrigerant or airflow problems can freeze coils and overflow drains. We thaw and clean components, preventing moisture damage inside your HVAC system.
  • Clogged Air Filters and Ductwork: Restricted airflow from dirty filters or duct blockages reduces energy efficiency and weakens cooling. Our technicians handle duct cleaning, duct sealing, and filter replacement for smooth circulation.
  • Thermostat Issues and Calibration Errors: A miscalibrated thermostat can cause uneven temperatures or short cycling. We check wiring, recalibrate thermostats, and ensure your settings match your comfort needs.

No matter the issue, our AC repair in Portland combines fast diagnostics with honest, upfront pricing so you always know what to expect.

Frequently Asked Questions about Air Conditioning in Portland, OR

We recommend annual maintenance before the cooling season begins, ideally in spring. Regular service includes cleaning coils, checking refrigerant levels, inspecting electrical connections, and replacing filters. This prevents breakdowns during hot weather and keeps your system running at peak efficiency.
Watch for weak airflow, warm air coming from vents, strange noises or odors, ice buildup on outdoor units, or higher than usual energy bills. If your AC runs constantly without cooling your home properly or refuses to turn on, those are urgent repair signals. Don’t wait—early diagnosis prevents larger problems.
Most central AC installations take one to three days, depending on your home’s size, ductwork condition, and whether existing infrastructure can be reused. We’ll provide a timeline estimate after our initial assessment so you know what to expect.
Most refrigerant leaks can be located and repaired by resealing connections or replacing damaged components, then recharging the system. However, if your unit is old and leaking frequently, replacement may be more cost-effective long-term. We’ll evaluate your specific situation and explain your options.
Work typically includes repair, installation, replacement, and seasonal maintenance for central air conditioners. Technicians diagnose airflow, electrical, and refrigerant problems and match equipment to the home’s cooling load.
