6 Overlooked Hvac Maintenance Tasks that Homeowners Shouldn’T Ignore
Maintaining a home's HVAC system is crucial, yet some simple tasks are often overlooked. This article sheds light on essential, yet frequently ignored maintenance actions, backed by advice from seasoned HVAC professionals. Discover the expert-endorsed steps that keep the home's air systems efficient and effective.
- Clean Your Furnace's Flame Sensor Regularly
- Inspect and Clean the Evaporator Coil Yearly
- Flush A/C Drain Line to Prevent Clogs
- Rinse Outdoor AC Unit Condenser Coils
- Change Thermostat Batteries Annually
- Clear Condensate Drain Line for Optimal Performance
Clean Your Furnace's Flame Sensor Regularly
One of the most overlooked HVAC maintenance tasks is cleaning or replacing the furnace's flame sensor--and in a place like Grand Rapids, where we rely on heating for months at a time, it's crucial.
The flame sensor is a small metal rod that detects if the burner is lit. If it gets dirty, the furnace can short-cycle or fail to ignite altogether. Homeowners often assume their furnace is broken when, in reality, a simple flame sensor cleaning could fix the issue.
Regularly cleaning this component ensures safe and efficient operation, reduces the risk of unexpected breakdowns, and helps avoid emergency service calls when it's freezing outside. During our annual maintenance visits, we always check and clean it--helping customers avoid no-heat situations in the dead of winter.
Inspect and Clean the Evaporator Coil Yearly
A maintenance task that's often overlooked is inspecting the evaporator coil. Located inside or near the air handler where the blower fan is, this coil absorbs heat from the air in your home. If it gets too dirty, your AC can't cool the house efficiently. Dirt and debris restrict airflow and insulate the coil, reducing its ability to absorb heat. This inefficiency means your system has to run longer, increasing your energy bills and putting extra stress on your HVAC equipment.
You should check the evaporator coil at least once a year and clean it as needed. While some homeowners feel comfortable doing this themselves, it can be a bit tricky depending on your system's setup, so calling in a professional isn't a bad idea. Keeping the coil clean helps your HVAC system run efficiently and can prolong its life, saving you money and hassle in the long run.
Flush A/C Drain Line to Prevent Clogs
An overlooked maintenance task in Florida is cleaning the A/C drain line. With our high humidity levels, algae and mold can quickly build up inside the drain line, causing clogs that lead to water leaks, system shutdowns, and even costly water damage.
Many homeowners don't think about their drain line until they see water pooling near their system. I always recommend flushing the drain line with vinegar or a commercial drain cleaner every few months to prevent buildup. During our maintenance visits, we make sure to clear and inspect it to avoid emergency calls during peak summer months. Preventative maintenance here can save homeowners from expensive repairs down the line.
Rinse Outdoor AC Unit Condenser Coils
One HVAC maintenance task that homeowners often overlook—but really shouldn't—is cleaning the condenser coils on their outdoor AC unit.
Over time, dirt, leaves, and debris build up on the coils, making it harder for the system to release heat. When that happens, your AC has to work twice as hard to cool your home, which can lead to higher energy bills, unnecessary wear and tear, and even system breakdowns.
A quick rinse with a hose a couple of times a year (or scheduling a professional cleaning during routine maintenance) helps keep your AC running efficiently, extends its lifespan, and prevents costly repairs. It's a small step that makes a big difference in keeping your home cool and comfortable!
Change Thermostat Batteries Annually
Many homeowners forget about changing their thermostat batteries until their system suddenly stops responding. I recommend that homeowners change their thermostat batteries at least once a year--ideally during daylight saving time changes, just like they would with smoke detector batteries. Some smart thermostats now provide low-battery alerts, but older models don't, so it's easy to overlook. A simple battery swap can prevent unnecessary A/C malfunctions and ensure that the system runs smoothly when you need it most.
Clear Condensate Drain Line for Optimal Performance
The One HVAC Maintenance Task Homeowners Often Overlook
One crucial HVAC maintenance task that homeowners often forget is cleaning the condensate drain line. This small but essential component helps remove moisture that builds up during the cooling process, preventing water damage and system malfunctions.
Why It's Important
1. Prevents Clogs & Water Damage - Over time, algae, mold, and debris can accumulate in the drain line, leading to clogs. A blocked drain can cause water to back up and leak, potentially damaging floors, ceilings, or even the HVAC system itself.
2. Improves Efficiency - A clogged drain can cause the system to work harder than necessary, reducing efficiency and increasing energy bills. Keeping it clear ensures smooth operation.
3. Reduces Mold & Musty Odors - Standing water in a clogged drain line can lead to mold growth, which can spread musty smells throughout the home and even affect indoor air quality.
4. Prevents System Shutdowns - Many modern HVAC units have a built-in safety switch that shuts the system down if the drain line is blocked. This can leave you without cooling or heating until the issue is resolved.
How to Maintain the Condensate Drain Line
(i) Flush it Monthly - Pour a cup of distilled vinegar or warm water with a bit of dish soap into the drain line to help break down buildup.
(ii) Check for Blockages - If water isn't draining properly, use a wet/dry vacuum on the exterior drain outlet to clear any clogs.
(iii) Install a Drain Line Cleaning Tablet - These help prevent algae growth and keep the line flowing smoothly.
Final Recommendation
Regularly maintaining your condensate drain line is a quick, easy, and inexpensive way to prevent costly repairs and system failures. Many homeowners overlook it, but doing this simple task can save you from major headaches down the road!
