Frequently Asked Questions on HVAC Services

  1. Which HVAC System is Right for My Home?

Answer: A ductless split system is a good choice if you want a safe and simple installation system. If you want to install your system outside, a packaged heating and air conditioning system makes sense.

  1. How Often Should I Service my HVAC System?

Answer: Typically, an HVAC system should be checked and serviced at least once a year. Good thing that HVAC Alliance Expert is one of Ontario’s most trusted HVAC installation companies.

  1. What Can Cause a Furnace to Break Down?

Answer: Below is the common causes of furnace issues: 

  • Ignition failure
  • Air leakage
  • Blocked vents
  • Clogged filters
  • Lack of regular maintenance
  1. What Kind of Filter Do I Need for my HVAC System?

Answer:Look for a thick filter, which often provides better air cleaning and lasts longer. Consider the filter’s design and compare filter longevity, particulate-capturing efficiency, and pressure drop using different ratings.

  1. How do I determine if my HVAC system is operating safely?

Answer: You must ensure that your home has working smoke and carbon monoxide detectors, which is an important HVAC safety precaution. Knowing that your HVAC system is not a safety hazard can give you peace of mind.
