What are signs your AC unit needs to be repaired?
Get your AC system repaired if you spot the following signs:
- Rising energy bills: If your energy bill is noticeably higher than usual or keeps going up, your AC system may be the culprit.
- Inconsistent temperatures: Your AC is designed to keep your home at a consistent temperature. Fluctuations in temperature from one room to the next could indicate an issue with your HVAC.
- Inaccurate thermostat readings: Your home's internal temperature should correspond to the thermostat. Mismatched temperature readings could mean there's a problem with your AC system or thermostat.
- Leaks around the AC unit: Get in touch with an air conditioning repair company as soon as possible if you see leaks around your AC. This could be due to leaking refrigerant or water from a broken or blocked tube.
- Weird noises: AC systems make some level of noise, but loud sounds or unusual noises, such as screeching, clicking or bubbling, can mean a bigger issue.
- Strange odors: Your AC may need repairs if it suddenly develops a lingering or weird odor.
- Weak airflow: A sign your AC may need repairs is poor or weak airflow. An inefficient air conditioning system or blockage could lead to weak airflow.
- Warm air: Your home's ductwork could have a problem, or your system's compressor could be low on refrigerant if your AC is circulating warm air.
- Frequent cycles: Your AC turning on and off more than usual may be a sign of a problem. Your system should turn on more often on warmer days, but it shouldn’t do so constantly during the day.

How do you choose the best AC repair company in Ontario?
These factors can help you choose the best AC repair company in Ontario.
Make sure the company is licensed in California
Verify that your AC repair company has licensing and insurance. The California Contractors State License Board requires HVAC contractors to maintain proper licensing. HVAC pros who work with refrigerants must be certified by the Environmental Protection Agency (EPA). Other requirements include a surety or cash bond and worker’s compensation insurance.
Look for national accreditations
Accreditation isn’t necessary, but it offers proof of the HVAC technician’s expertise and ability in the field. Two professional accreditation associations include the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and the Air Conditioning Contractors of America (ACCA).
Get a free estimate
Take advantage of free estimates, which most HVAC repair companies offer. This includes a technician coming to your home to assess the problem, recommend solutions and give you a quote. The technician should thoroughly inspect your AC system before diagnosing the issue.
Compare costs
Request detailed quotes from several providers to compare costs. Reviewing rates from multiple providers will help you get an idea of the average local price range. Use caution with companies that have unusually high or low rates.
Assess experience
Make sure to ask how familiar the air conditioning repair provider is with your AC's brand and model. HVAC pros work with several types of heating and cooling equipment, but some have expertise in certain types of systems.
Read reviews
Ask your family and friends if they have any recommendations for local AC repair companies. And always check a company’s online reviews.
Read comments from past customers to better understand their experience with the company, and look for consistently bad reviews or a recent rise in negative reviews.
What are popular types of AC units in Ontario?
The following are the most common types of AC units in Ontario and the homes they’re most suitable for:
- Central: Standard central AC units are reliable and designed to efficiently cool entire homes, making them well-suited for hot climates.
- Ductless mini-split: The ductless mini-split is another common type of AC unit. It's a reliable choice for homes without ductwork.
- Hybrid: Hybrid systems combine heat pumps with furnaces, providing cooling during hot weather and heating during colder seasons.
- Heat pumps: Heat pumps are becoming more popular in Ontario, as they’re more energy-efficient and work best in warmer climates.
