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 .

Hot water was 97f coming out of mixing valve with tank set very high. Set water heater back to “A” and adjusted mixing valve. Temp clamp on pipe out of mixing valve was 127f and thermometer at hot water tap was reading upwards of 135f after adjusting the mixing valve. Customer is much happier with this as she likes her water on the hotter side.

Fixed gas leak on supply line. Removed 2 street 90s from water heater gas line. Ensured furnace and water heater were both running before leaving. Current water heater 16-17 years old, in poor condition. Rust developing at seams, only a matter of time before it lets go. Strongly recommend replacing water heater in the near future.

Lennox furnace maintenance and inspection. Furnace had problems recently causing no heat. Checked previous error codes and found pressure switch codes related it to it being stuck open and stuck closed at times. Replaced with universal pressure switch. Performed full maintenance on unit, tested all components. Furnace is still operating safely at this time. Furnace is 13 years old so should hopefully be problem free for at least another few years. Typical life span is 15-20yrs. Found no other problems during visit
