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 .

I completed a single-stage Lennox high-efficiency furnace inspection and maintenance. I found no immediate faults, but I performed a thorough inspection and cleaning. I checked the flame sensor, burners, pressure switch, inducer, and drain system. I verified the ignition sequence and combustion, and the flame signal, temperature rise, and overall operation were within the acceptable range. I advised the client that a proper cleaning and servicing often resolves minor intermittent issues, and the system is currently operating normally. I mentioned that due to the age of the equipment, replacement may be worth considering in the future, as parts availability can become limited.

I performed maintenance on a 2-stage Keeprite high-efficiency furnace. I inspected, cleaned, and checked all components to ensure they were operating within manufacturer specifications. The furnace was installed in 2020, so it is not very old. I noticed that the humidifier was not wired up, so I advised the client that a service call would be required to diagnose and reconnect if desired. I left the humidifier off for now.
