What Pacific Northwest Homeowners Can Expect When Replacing Their HVAC Unit

There comes a time in the life of every HVAC system when it makes way for a newer, more efficient successor. 

As a homeowner, you may be dreading that day. After all, it has been a long time since you bought a new air conditioner, heat pump, or gas furnace. Maybe you are overwhelmed by the features available and unsure what to expect when installing a new system.

When Should I Replace My HVAC Unit?

Before we dive into the installation process, it’s essential to know if you actually need a replacement. Here’s how long HVAC equipment typically lasts:

  • Gas Furnaces—15-20 years 
  • AC Units—12-17 years
  • Heat Pumps—10-15 years

Signs You Should Replace Your HVAC Unit

Age alone isn’t the sole reason to replace HVAC equipment. If your older equipment shows any red flags, consider replacement.

  • Repairs: Your system needs repairs more than once a year.
  • Bills: Your utility bills have increased while your usage habits haven’t changed.
  • Noises: Grinding, whistling, banging, and other odd sounds may indicate mechanical failure. 
  • Comfort Issues: One room is cold, and another is too hot. 

Carrier recommends following the “$5,000 rule” to help you decide if repair or replacement is best. If you anticipate repairs will exceed $5,000 over the remaining life of your system, it’s more cost-effective to replace it. Investing in a new unit instead of repairs can save money and improve comfort in the long run. 

Our Carrier Northwest directory can point you toward an expert team to diagnose HVAC red flags and determine if a repair or replacement is best. 

How Long Does HVAC Installation Take?

During an in-home visit, a Carrier dealer will determine the equipment size you need, discuss product options, and outline project costs and details. You will receive an estimate for the job, and when you are ready to move ahead with the work, you will select a time and date for installation. 

Here is what to expect for the four most common replacement scenarios: 

How Long Does It Take to Replace a Gas Furnace and AC?

Expect the crew to spend eight to 12 hours at your home. The installers replace the indoor furnace, the evaporator coil, and the outdoor condenser unit. Because gas lines, electrical work, and refrigerant are involved, the installation typically takes a full workday.

How Long Does It Take to Replace a Gas Furnace?

Since the outdoor unit remains, the installers focus entirely on equipment in the indoor mechanical room or crawl space. The technicians will disconnect the gas and exhaust venting, slide out the old unit, and meticulously seal the new furnace into your existing ductwork. The total time is approximately four to eight hours. 

How Long Does It Take to Replace an AC Unit?

Replacing AC involves swapping the outdoor condenser and the indoor evaporator coil. The team will reclaim the old refrigerant in accordance with EPA standards, install the new equipment, and pressure-test the lines to ensure there are no leaks, all within four to eight hours.

How Long Does It Take to Replace a Heat Pump?

Expect the crew to be in your home for six to 10 hours. Because a heat pump provides both heating and cooling, it requires complex electrical wiring and refrigerant configurations, although this is usually a same-day job. Complex dual-fuel or multi-zone systems may lean toward the longer end of the timeline.

HVAC Installation Process

The companies in our Carrier Northwest directory follow strict protocols during installations. Technicians place floor runners and plastic to protect your carpets and furniture before connecting your old system, recovering refrigerant, shutting off the gas, and removing the equipment.

Your ductwork may need adjustment if your new high-efficiency system has different dimensions from your existing heating and cooling unit. If you are upgrading from a standard efficiency furnace to a condensing unit, you will need dedicated piping for condensate and exhaust. Pipes generally run through a wall to the outdoors.

The crew installs the new equipment and connects the gas, electrical, and refrigerant lines. A technician will test the airflow to ensure it is perfect and the refrigerant line is clean and charged correctly. 

Before leaving, the installers will demonstrate thermostat use and show you how to change air filters.

Prepare Your Home for HVAC Installation

You can help make the day go smoothly with these simple actions: 

Clear Clutter: Move any clutter away from the indoor furnace or air handler and ensure there is at least a three-foot clearance around the outdoor unit.

Secure Pets: The noise of power tools and open doors can be stressful for furry friends. Keep them in a separate room. 

Access Areas: Ensure the technicians can access your electrical panel and thermostat.

Remain On Hand: You don’t need to hover, but being available can be helpful if the crew has questions.
