St. Catharines, ON HVAC FAQs

Why is my air conditioner not blowing cold air near St. Catharines?

Is warm air coming out of your vents with the thermostat set to cool? If so, your air conditioning issue could be quite simple.

The most common cause is a dirty air filter, which requires a simple replacement. Other causes include:

  • Fan/fan motor malfunction
  • Broken thermostat
  • Control board damage

For an accurate diagnosis when your AC is not blowing cold air, call Evan’s for assistance: 289-203-7248 .

How many years do air conditioners last near St. Catharines?

Air conditioners last about 10 - 15 years. You may have one that is older and still blowing out cold air, but older ACs are not only a ticking time bomb but less energy efficient as well. The lowered efficiency translates to higher energy bills.

Evans can inspect your air conditioner if you are experiencing cooling issues and let you know if yours is on the way out or just needs a repair. Call 289-203-7248 for assistance.

What size air conditioner do I need near St. Catharines

Air conditioners are sized based on the square footage of your home. As a rule of thumb, each square foot needs 20 Btu. You may think you can determine the size you need yourself, but you might leave out important considerations such as ceiling height and the size of your windows and doorways,

A professional HVAC tech in St. Catharines can calculate the precise air conditioner size you need. Get in touch with someone who can help by calling 289-203-7248 .

Keeprite ac maintenance Upon arrival, customer stated that they find their air conditioner to be noisier this year Upon testing the unit and verifying pressures found the unit to be having an almost 50° sub cool on the unit, unit requires 10°. Compressor is very noisy. Unit appears to be overcharged with refrigerant, has shirt Linsey which coil be part of the issue (10 feet approximately) unable to recover any refrigerant as I do not have a recovery cylinder Will have to quote out the cost to return and recover some refrigerant and see if that helps with the pressures and noise level We did not install this AC The issue that we could have if we leave the unit as it is is due to the overcharge of refrigerant compressor could fail in the future Unit is working at this time

Kyle from Evans helped us out in a pinch when our 20 year old furnace quit late on a Friday afternoon. He was at our house within 30mins of calling to check out the unit. The entire Evans team was great to deal with from start to finish and were able to get our furnace installed quickly so we wouldn’t be without heat! 10/10 would highly recommend Evans for anything heating/ cooling related.

We called Evans Heating & Cooling to service our fireplace and they were able to come within 24 hours. The service technician explained everything he was doing in detail, cleaned the fireplace, painted the fireplace, rearranged the logs to be more aesthetically pleasing, and added some embers. The fee was well worth it, and above everything else he was so friendly. Highly recommend!!
