DIY HVAC & Plumbing Maintenance Tips

While it’s important to call in a professional if you notice strange noises, inconsistent performance, or higher utility costs, homeowners can handle basic upkeep.

Regular maintenance is one of the simplest ways to save money on unexpected repairs and extend the lifespan of your system.

Staying on top of routine care helps your equipment run more efficiently, reduces wear and tear, and can lower your energy bills over time.

Air Conditioning

Check Your Thermostat

Ensure the system is set to heat or cool with the fan on auto. The temperature setting should be lower than the current temperature if you need cooling or higher if you need heating.  

Clear Debris from the Outdoor Unit

Keeping your air conditioner clean helps it run more efficiently and prevents damage. Ensure the unit isn’t crowded by landscaping or other items.

Remove the protective cover from the outdoor unit’s fan. Use a hose or a wet/dry vacuum to clean out any leaves, dirt, or debris that may have collected inside.

Change the Air Filter

Most filters should be changed every three months, but that can vary depending on the filter type, home size, and whether anyone in your household has allergies.

Furnaces

Change Your Air Filter

A clogged filter restricts airflow, forcing the blower to work harder and increasing energy use. Clean filters also help remove dust, allergens, and other pollutants from your home’s air.

Remove the furnace filter from the panel on the lower half of your furnace.

Keep Spaces In & Around Units Clear

Keep the area around your furnace free of dust, dirt, and clutter. Regular sweeping and vacuuming help prevent debris from entering the unit.

Avoid storing paint, cleaners, or other chemicals near your furnace, as fumes can be drawn into your home through the system’s air intake.

Check for a Blue Flame on a Gas Furnace

The flame color indicates that your gas furnace is operating efficiently with complete combustion. It also means a hotter burn and less carbon monoxide.

If you have a yellow or orange flame, you could be at risk for carbon monoxide buildup.

Heat Pumps

Clear Outdoor Debris

Keep the area around your heat pump’s outdoor unit free of leaves, branches, and other debris.

Replace or Clean Filters

To improve airflow, boost efficiency, and maintain indoor air quality, check your filters monthly and clean or replace them as needed.

Clean Outdoor Coils

Dirty coils reduce heat transfer and force the system to work harder, so inspect the outdoor coils and gently clean them if dirt or buildup is visible.

Dust Supply & Return Registers

Regularly clean your home’s supply and return registers to remove dust and improve airflow. 

Plumbing

Inspect for Leaks

Routinely check under sinks, around toilets, and near water heaters for signs of leaks or moisture.

Catching small leaks early can prevent water damage and reduce your utility bills.

Check for Corrosion

Look for signs of rust or discoloration on exposed pipes and fittings.

Exercise Shut-Off Valves

Turn your water shut-off valves on and off a few times each year to prevent them from seizing. 

Drain & Sewer

Watch What Goes Down the Drain

Only human waste and toilet paper should go down the toilet.

Food scraps, cooking grease, wipes, and feminine hygiene products should all go in the trash.

In the shower, use a drain screen to catch hair rather than letting it cause a drain clog.

Pay Attention to Drainage Issues

Slow drains, gurgling noises, or water backing up may signal a clog or break in your sewer main.

Watch for warning signs like multiple clogged fixtures, foul odors, or soggy patches in your yard.

Canady's installed two new water heaters in my home yesterday. My technician, Tim B., did an outstanding job. He is very knowledgeable, polite, and efficient. He also hooked up the ice maker in my new refrigerator a month or so ago. It was a very difficult job and he did a great job. I would recommend Canady's to anyone. Tim is an awesome technician! Thank you, Tim for the jobs well done!

I am beyond satisfied with this company. The technician did not try to sell a bunch of products to us. Instead, he accomplished the job he was sent here to do very thoroughly and with detail, making our A/C function in the best possible fashion! He was polite and timely. I will absolutely be servicing our unit yearly from now on with Canady’s!

Mr. Shepherd was very considerate and professional upon arrival and throughout his visit. He explained everything in detail and went above and beyond all the while being considerate of property. Canady's is pricey but the old saying applies, you get what you pay for. I might add that the customer experience was second to none, they always give updates whether by phone text or email - top notch. All in all, the best choice!
