What to know about the AC install process:

The Pre-Installation Evaluation

The first step to replacing your current air conditioner is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at Mainstream how much heat your house gains throughout the day and what size air conditioner will work best to keep it cool. This is critical as many air conditioning issues stem from an improperly-sized air conditioning unit.

Do You Have Usable Ductwork?

Sometimes your old existing ducts can't handle the airflow of a newly installed air conditioner. Upgrades to your ductwork to accommodate a new HVAC system will likely increase the cost to install an AC unit, but will ultimately help you avoid costly, high energy bills and hot rooms in the future.

Choosing the Right Size AC System

Here's where the load calculation comes into play, as you want to pick the right size air conditioning unit to install in your Spokane home - either too big or too small of an AC unit can lead to costly repair or replacement down the road.

The HVAC professionals at Mainstream will be able to guide you on which AC unit works with your needs and budget.

Professional, friendly, efficient and courteous.

Had my water system upgraded, gas lines installed, additional electrical service, furnace and A/C systems replaced, and some plumbing corrections. I had just moved into the house and found a one-stop-shop for all of the essential home systems to be updated and repaired/replaced. They follow up, show up on time, and even call after hours to ensure good customer service. Robert, Zach, Megan, Shane, Kyle, and a few whose names I didn’t catch. All have been a pleasure to have work in my home.

Very Happy

We had them come out for a yearly maintenance on our water heater. They were thorough and gave good recommendations for continued maintenance and use. We also had them install a new furnace and air conditioning unit. They were very quick and efficient. All the crew members were courteous and respectful of our home. I am very happy to recommend them to others.
