Frequently Asked Questions

AC Installation & Replacement

An air conditioner that is too small for your home may struggle to keep up during hot weather, run constantly, and leave certain rooms feeling warmer than others. Signs of an improperly sized AC system can include uneven temperatures, poor airflow, hot spots, and reduced comfort throughout the house.
Most air conditioner installations can be completed in one day, though complex projects or system upgrades may take longer.
AC installation cost depends on system size, efficiency rating, and home requirements. Mainstream provides upfront pricing and financing options so you know your investment before work begins.
Whether you should repair or replace your AC unit depends on the age of the system, the cost of repairs, and how reliably the air conditioner is performing. Smaller repairs, like replacing a capacitor or electrical component, are often worth fixing. However, if your air conditioner needs major repairs, experiences repeated breakdowns, or struggles to cool your home properly, replacing the system may be the better long-term investment.
Professional AC installation includes system sizing, safe removal of old equipment, electrical and refrigerant connections, thermostat setup, and full performance testing to ensure efficient, code-compliant operation.

Professional Air Conditioning Installation & Replacement in Spokane

Upgrading your air conditioning system is a big decision, especially in Spokane, where summer heat can hit hard and older systems often struggle to keep up. Whether your AC is constantly running, cooling unevenly, or driving up energy bills, replacing it with a properly sized high-efficiency system can make a noticeable difference in comfort and reliability.

When It’s Time to Replace Your AC

Most air conditioners start showing their age after 10–15 years. You may notice longer run times, inconsistent temperatures between rooms, rising utility costs, or more frequent repairs. In many cases, replacing the system is more cost-effective than continuing to patch an aging unit together every summer.

At Mainstream, we install central air conditioners and heat pumps designed for Spokane-area homes and the Inland Northwest climate. Our licensed HVAC technicians evaluate your home’s layout, insulation, existing ductwork, and overall cooling demands to recommend the right solution, not just the biggest system available. Proper sizing matters, and an incorrectly sized unit can lead to short cycling, humidity issues, and unnecessary wear over time.

Installing AC in Older Spokane Homes

Not every home in Spokane was built with central air conditioning in mind. Many older homes, rural properties, and houses throughout the Inland Northwest still rely on window units or outdated cooling methods. If you’re adding AC for the first time, we’ll help you understand what makes the most sense for your home and budget.

For some homes, traditional central air is the best fit. For others, ductless mini-splits or heat pumps may offer better efficiency and easier installation without major renovations. We’ll walk you through the pros and cons of each option clearly, so you can make the right decision without feeling pressured.

What’s Included With Professional Installation

A quality AC installation involves much more than swapping out equipment. Our team handles the details that help your new system perform efficiently from day one, including:

  • Removal and disposal of old equipment
  • Electrical and refrigerant line inspections
  • Airflow testing and system calibration
  • Thermostat setup and communication testing
  • Final performance checks before we leave

We take the time to make sure everything is operating correctly and your home is cooling evenly before the job is complete.
