Ways Your Air Conditioner Can Break

There are several common ways an air conditioner can break down. Here are some of the most frequent issues:


1. Refrigerant Leaks

  • Symptoms: Inefficient cooling, hissing sounds, ice buildup on the evaporator coil.
  • Cause: Punctures in the refrigerant lines or factory defects.
  • Solution: Professional repair to locate and fix the leak, then recharge the refrigerant.

2. Dirty or Clogged Filters

  • Symptoms: Reduced airflow, increased energy bills, uneven cooling.
  • Cause: Neglecting regular maintenance and replacement.
  • Solution: Replace or clean filters every 1-3 months.

3. Frozen Evaporator Coils

  • Symptoms: Warm air from vents, frost on coils, frequent cycling.
  • Cause: Poor airflow, dirty coils, low refrigerant levels.
  • Solution: Turn off the AC to thaw the coils, clean or replace the filter, and check refrigerant levels.

4. Faulty Thermostat

  • Symptoms: Incorrect temperature readings, unit cycling on and off.
  • Cause: Calibration issues, sensor problems, dead batteries.
  • Solution: Replace batteries, recalibrate or replace the thermostat.

5. Blocked Condenser Unit

  • Symptoms: Reduced cooling efficiency, high energy bills.
  • Cause: Debris, dirt, and foliage blocking the condenser.
  • Solution: Regularly clean the unit and keep the area around it clear.

6. Electrical Issues

  • Symptoms: AC not turning on, tripped breakers, frequent cycling.
  • Cause: Faulty wiring, blown fuses, capacitor problems.
  • Solution: Inspect wiring, replace fuses, and check capacitors.

7. Drainage Problems

  • Symptoms: Water leaks, musty odors, humidity issues.
  • Cause: Clogged condensate drain, disconnected drain line.
  • Solution: Clear the drain line and ensure proper drainage.

8. Compressor Failure

  • Symptoms: AC not cooling, loud noises from the unit.
  • Cause: Electrical issues, refrigerant problems, lack of maintenance.
  • Solution: Professional repair or replacement of the compressor.

9. Fan Problems

  • Symptoms: Poor airflow, strange noises, unit not turning on.
  • Cause: Motor issues, worn belts, lack of lubrication.
  • Solution: Inspect and repair or replace the fan motor, belts, and bearings.

10. Sensor Problems

  • Symptoms: Inconsistent temperatures, unit cycling on and off.
  • Cause: Misplaced or malfunctioning sensors.
  • Solution: Adjust the sensor position or replace it.

Prevention Tips:

  • Schedule regular maintenance checks.
  • Replace or clean filters regularly.
  • Keep the outdoor unit free from debris.
  • Ensure proper thermostat settings and calibrations.

Regular maintenance and prompt attention to any irregularities can help keep your air conditioner running smoothly and efficiently.

My old furnace had finally broken down for the last time when contacted twintech to have a new furnace installed…They were prompt, knowledgeable and very reasonably priced. They did such a great job i tell all my friends and family about this company.

by Damien McIsaac. Ajax on Twintech Heating and Cooling

To whom it may concern, I recently had TwinTech (Greg and Grant Dainty) replace my furnace and service both my gas fireplaces and air conditioning unit. They were professional, courteous and very fair in their pricing. I would gladly recommend TwinTech to anyone needing work done. I can be contacted at 905-626-XXXX.

by Blair N. - Toronto on Twintech Heating and Cooling

My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment

by Ruth on Twintech Heating and Cooling

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

by Anna Chin on Twintech Heating and Cooling

Amazing experience with TwinTech Heating & Cooling! Their team was professional, knowledgeable, and efficient from start to finish. They installed my new furnace quickly and left everything spotless. The technicians took the time to explain everything and made sure I was comfortable with the system before they left. Great customer service and fair pricing. I highly recommend them for anyone needing HVAC services!

by Connor Agnew on Twintech Heating and Cooling

Great experience all around. Bob was sharp and easy to talk to, and Greg handled the installation perfectly. Would hire them again in a heartbeat.
