Spring HVAC and Plumbing Prep: Get Your Home Ready Before the Heat Hits

Spring is the best time to give your home's mechanical systems a once-over. After a hard Scranton winter, your HVAC and plumbing have been working overtime — and a few hours of maintenance now can prevent an emergency call on the hottest day of July.

Here's exactly what to check.

HVAC: Outdoor Air Handler and Condenser

Clean or Replace the Air Filter

This is the single highest-impact thing you can do. A clogged filter forces your system to work harder, raises your energy bill, and shortens the life of your equipment. For most homes, replace the filter every 1–3 months during heavy-use seasons.

How to do it: Turn the system off at the thermostat, locate the filter slot on the air handler (usually in the basement or utility closet), slide out the old filter, note the size printed on the frame, and install a new one with the airflow arrow pointing toward the blower.

Clear the Outdoor Condenser Unit

Over winter, leaves, dirt, and debris collect around and inside your outdoor condenser. Restricted airflow here means the system can't reject heat efficiently — which means higher bills and more wear.

How to do it:

• Turn off power to the unit at the disconnect box next to it
• Remove any debris from around the base (maintain at least 2 feet of clearance on all sides)
• Gently rinse the fins with a garden hose from the inside out — never a pressure washer
• Straighten any bent fins with a fin comb if you have one

Test the System Before You Need It

Don't wait for the first 80° day to find out your AC isn't cooling. Turn it on in mid-spring when outdoor temps are above 60°F (running AC when it's colder can damage the compressor). Let it run for 15 minutes and confirm cool air is coming from the vents.

If you hear grinding, smell something burning, or the system short-cycles (turns on and off rapidly), call a technician before the summer rush.

Plumbing: Post-Winter Check

Inspect Hose Bibbs (Outdoor Spigots)

Freezing temperatures can crack outdoor faucets even when you've disconnected the hose. Spring is when those cracks show up as leaks.

How to check: Turn each outdoor spigot on fully. Watch for water dripping from the wall behind the spigot — that's a sign of a cracked pipe inside. Also check the spigot itself for drips when fully open.

Check Under Sinks and Around Water-Using Appliances

Frost heave and temperature swings can loosen connections over winter. Do a quick visual inspection under every sink and around the dishwasher, washing machine, and water heater.

Look for:

• Mineral deposits or water stains (signs of a slow drip)
• Soft spots in the cabinet floor
• Rust on supply lines or shutoff valves

Flush Your Water Heater

Sediment builds up at the bottom of your tank over time, reducing efficiency and shortening the heater's life. Flushing it once a year — spring is a good time — keeps it running well.

How to do it: Connect a hose to the drain valve near the bottom, run it to a floor drain or outside, turn the valve, and let it run until the water runs clear. If you've never done this on an older heater, have a plumber do it the first time — old valves can fail to reseat.

When to Call a Pro

Some of this is straightforward DIY. But if you find:

• Ice damage on refrigerant lines
• No cool air after 15 minutes of running
• Water stains on ceilings or walls
• A water heater over 10 years old making popping sounds

…it's worth a call before small issues become expensive ones.
