Maintenance Checklist for the Goodman GLXS4BA3610 / CAPTA3626C3 / GR9T961005CN System

Intro from Mike 👋

Hey there, homeowners and HVAC warriors. Mike here. If you’re running that solid Goodman 3-ton setup with the GLXS4BA3610 R‑32 condenser, CAPTA3626C3 vertical coil, and that GR9T961005CN 96% AFUE gas furnace, you’ve already made a smart move. But even the best gear needs a little TLC.

Neglect it, and you’re asking for breakdowns in the middle of summer—or worse, during a deep freeze. So let’s dig into the checklist that’ll help you protect your system, preserve your warranty, and keep your energy bills in check. Grab a flashlight and maybe a cup of coffee—we're diving in. ☕🔧

 

1. Inspect & Replace Air Filters – Monthly or Quarterly

One of the easiest ways to avoid airflow issues and inefficiency is by checking your filters. Depending on your home’s dust level and if you’ve got pets, you’ll want to swap them out monthly or at least every 90 days.

Clogged filters force the blower to work overtime, which reduces the lifespan of the motor and increases your utility bill.

2. Clean the GLXS4BA3610 Condenser – Twice a Year

That outdoor R-32 condenser unit takes a beating. Leaves, grass clippings, dirt—all of it builds up and messes with heat transfer.

Make sure to:

  • Power off the unit

  • Remove debris from the coil fins

  • Use a garden hose (not a pressure washer!) to rinse from inside out

  • Straighten bent fins with a fin comb

Also, keep at least 2 feet of clearance around the unit.

3. Check the CAPTA3626C3 Coil for Dust & Mold

This vertical evaporator coil inside your air handler or furnace plenum needs attention too. A dirty coil means lower efficiency and higher humidity.

Things to look for:

  • Dust buildup from leaky ducts

  • Signs of mold (use a flashlight)

  • Clogged drain pans or blocked condensate lines

Drain line clogs are a common issue and can be cleared using a wet/dry vac.

4. Test Blower & Thermostat Settings

Your blower motor is the heart of airflow. Make sure:

  • It runs smoothly at startup

  • You don’t hear any loud humming or rattling

  • Airflow feels strong through vents

Also, confirm your thermostat is reading and cycling correctly. If you’ve got an old-school thermostat, now might be the time to upgrade to a smart one for better control and energy savings.

👉 Consumer Reports reviews the best smart thermostats.

 

5. Annual Furnace Safety Inspection

This is where things get serious. Your GR9T961005CN gas furnace needs a pro to:

  • Inspect the heat exchanger for cracks

  • Test gas pressure and flame

  • Clean the burner assembly

  • Check for carbon monoxide leaks

If anything’s off, it’s a safety risk and a code violation. Get this checked before every heating season.

Bonus Tip 🔍: Check R-32 Pressure & Charge Annually

While R-32 refrigerant runs with lower GWP (yay, environment!), it also operates at high pressure and needs precise charging. Only certified techs should do this, using digital gauges and scales.

Always look for:

  • Frost on lines

  • Weak cooling performance

  • Hissing or bubbling sounds (leaks!)

Don’t top it off blindly—weigh it, don’t guess it.
