AC Repair Services

When your air conditioner breaks down during a heat wave, every minute matters. Our experienced technicians can diagnose and repair most AC repair issues quickly and efficiently. We service all major AC brands and models, handling problems such as:

  • AC not cooling: If your air conditioner isn't producing cold air or can't maintain comfortable temperatures, we'll identify and fix the problem.
  • AC won't turn on: Problems with power, thermostat, or internal components preventing startup.
  • Refrigerant leaks: Low refrigerant reduces cooling capacity and efficiency. We locate and repair leaks, then recharge the system.
  • Frozen evaporator coils: Restricted airflow or refrigerant issues can cause coils to ice up.
  • Strange noises: Grinding, squealing, or banging sounds indicate mechanical problems requiring attention.
  • Water leaks: Clogged drain lines or other issues causing water damage.
  • Short cycling: AC turning on and off frequently reduces efficiency and comfort.
  • Poor airflow: Weak airflow from vents suggests blower or ductwork problems.
  • High energy bills: Inefficient operation dramatically increases cooling costs.
  • Thermostat malfunctions: Faulty thermostats prevent proper temperature control.

AC Installation Services

Installing a new air conditioning system is a significant investment in your home's comfort and value. Our professional AC installation service ensures your new cooling system is properly sized, correctly installed, and optimized for maximum performance and efficiency. We work with leading AC manufacturers to provide reliable, energy-efficient options.

Our AC installation process includes:

  • Comprehensive home cooling assessment and load calculation
  • Accurate system sizing based on square footage, insulation, and cooling requirements
  • Recommendations for the most efficient AC models for your situation
  • Professional removal and disposal of your old AC system

  • Ductwork inspection: Looking for leaks or damage reducing efficiency.
  • Performance testing: Measuring cooling capacity and energy efficiency.

AC Replacement Services

Sometimes AC replacement is more cost-effective than continuing repairs. Consider air conditioner replacement when:

  • Your AC is over 10-15 years old
  • Repair costs exceed 50% of replacement cost
  • Your AC frequently breaks down
  • Energy bills have increased significantly
  • The AC can't maintain comfortable temperatures
  • Your system uses outdated R-22 refrigerant
  • You're experiencing uneven cooling throughout your home
  • The AC is improperly sized for your space

Modern air conditioners are significantly more efficient than older models. A new high-efficiency AC installation can reduce your cooling costs by 30-50% while providing superior comfort.

Common AC Problems and Solutions

AC Not Cooling Properly

If your air conditioner runs but doesn't cool effectively, potential causes include:

  • Low refrigerant: Often due to leaks in the system.
  • Dirty air filters: Restricted airflow reduces cooling capacity.
  • Dirty coils: Buildup on evaporator or condenser coils impairs heat transfer.
  • Faulty compressor: The compressor is essential for refrigerant circulation.
  • Thermostat issues: Incorrect settings or malfunctions affect cooling.
  • Ductwork leaks: Cool air escaping before reaching living spaces.

AC Won't Turn On

When your air conditioner won't start, check for:

  • Tripped circuit breaker or blown fuse
  • Thermostat problems or dead batteries
  • Faulty capacitor or contactor
  • Blown control board fuse
  • Damaged wiring or connections
  • Safety switch activation

AC Making Strange Noises

Different sounds indicate different problems:

  • Grinding or squealing: Belt or bearing issues in the blower motor.
  • Banging or clanking: Loose or broken components inside the unit.
  • Hissing: Refrigerant leak or expansion valve issues.
  • Clicking: Electrical problems or failing compressor.
  • Buzzing: Electrical issues, loose parts, or debris in the unit.

AC Water Leaks

Water leaking from your AC can result from:

  • Clogged condensate drain: Most common cause of water leaks.
  • Frozen evaporator coils: Ice melting and overflowing the drain pan.
  • Cracked drain pan: Rust or damage causing leaks.
  • Low refrigerant: Can cause coils to freeze.
  • Improper installation: Unit not level or drain line issues.

AC Efficiency and Energy Savings

Modern air conditioners offer significant efficiency improvements. When comparing AC units, look at the SEER (Seasonal Energy Efficiency Ratio) rating:

  • Minimum Efficiency: 13-14 SEER (current minimum standard)
  • High Efficiency: 16-18 SEER
  • Ultra-High Efficiency: 20+ SEER

Higher SEER ratings mean greater efficiency and lower operating costs. A new high-efficiency AC installation can dramatically reduce your summer cooling bills. Regular AC maintenance also plays a crucial role in maintaining efficiency.

Frequently Asked Questions About AC Service

We recommend professional AC maintenance at least once per year, ideally in spring before the cooling season. Regular maintenance prevents breakdowns, improves efficiency, and extends your AC's lifespan.
With proper maintenance, most air conditioners last 12-15 years. Factors like usage, maintenance frequency, and climate affect lifespan. If your AC is approaching this age and experiencing frequent problems, consider AC replacement.
Proper AC sizing requires a professional load calculation considering square footage, insulation, windows, ceiling height, and more. An oversized AC cycles too frequently and doesn't dehumidify well, while an undersized unit can't maintain comfort. Our technicians perform detailed calculations for optimal sizing.
Consider AC replacement if your unit is over 10 years old and repair costs exceed 50% of replacement cost. Factor in energy savings from a new, efficient system. Our technicians can help you evaluate whether repair or replacement makes more financial sense.
Reduce cooling costs by: scheduling regular AC maintenance, changing filters monthly, using a programmable thermostat, sealing air leaks, adding insulation, using ceiling fans, and keeping blinds closed during peak sun hours. Consider upgrading to a high-efficiency AC for maximum savings.
