Importance of Annual AC Maintenance

It is important to consider regular preventative maintenance and AC servicing for the following reasons:

Improves efficiency and performance

Extends the lifespan of your AC

Saves money on energy expenses and potential costs on repairs and replacements

Improves indoor air quality

Ensures maximum comfort

Improves your home’s resale value

Our air conditioner experts recommend taking a proactive approach and attending to any concerns and issues with your air conditioners as soon as you notice them. Get in touch with us to know more about our HVAC maintenance programs offered across Okotoks. You can contact us to buy highly efficient air conditioners too.

Does the Furnace Affect the AC?

No, both the furnace and the AC work separately. Your air conditioning system uses the same distribution system as the furnace, but the AC’s outdoor unit is not connected to the furnace in any way. If you require furnace repair services, our skilled technicians can help with that too.
