Signs It’s Time to Replace Your AC

Air conditioning systems are one of the most important major appliances you have in your home. Many of us rely on the comfort of a cool home in the middle of summer. We need that system running at capacity, and if you’ve been having trouble with your AC, you may be ready to consider a full AC replacement rather than calling in a technician for more repairs. If you’re considering whether to repair or replace your AC system, there are a number of factors to consider:

Air Conditioner is Outdated

Most AC systems have a maximum lifetime of about 10 to 15 years if properly maintained. So, if your unit is approaching or is over ten years old, you should start preparing for an AC replacement in the near future. Like other technologies, HVAC systems have drastically improved in the past decade, with newer models designed to be more energy efficient and use sustainable refrigerants. Installing a new air conditioner, rather than repairing an outdated system, could help you lower your energy bills and repair costs over time.

AC Needs Repairs Frequently

Many common air conditioning issues are caused by a lack of proper maintenance, especially when you consider that technicians can spot potential problems before they require large repairs. If you get your air conditioner serviced annually and still find yourself sweating at home, wondering how to stay cool while you wait on AC repairs, purchasing a new AC may be more economical than continually repairing your current system – especially when you consider that older parts can be more expensive and difficult to find. 

AC Unit Isn’t Cooling Your Home Consistently

A lack of consistent, cool air is an obvious sign your air conditioner is experiencing issues. Your air conditioner should provide cool air throughout your home, so if you feel warm air flowing through your vents or have limited airflow, you will need to call a Spokane air conditioner company immediately. A lack of airflow or warm air could indicate a serious issue with your ducts or your central air conditioning unit.

Utility Bill Goes Up Unexpectedly

If temperatures have remained consistent, but your energy bills keep increasing, you likely have a problem with your central air conditioner. As air conditioners age, it's common for energy costs to increase. Receiving a couple of high energy bills occasionally shouldn't raise major concerns. However, if your energy expenses consistently remain high, it could indicate that it's time to look for a newer, more efficient AC system.

Features to Consider When Installing a New AC System

With so many options available for air conditioning systems, how can you determine which one is right for you? Don’t worry! Our expert AC installation technicians can help!

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. Alternatively, you may want to consider a ductless mini-split system to meet your heating and cooling needs, since they dont require ductwork to operate.

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.
