The Essential Winter HVAC Checklist: Preparing Your Home for the Cold

As the leaves turn and the cool whispers of winter begin to wrap around our homes, it's not just our wardrobes that need changing. Our living spaces demand a seasonal transition too, particularly when it comes to heating. Preparing your HVAC system for the cold is crucial, not just for comfort but also for efficiency and safety. Sharony HVAC is here to guide you through the essential winter HVAC checklist.

1. Replace or Clean Air Filters

Starting with the basics, air filters are the lungs of your HVAC system. Over time, they collect dust and debris, which can impede airflow and force your system to work harder. Before winter sets in, ensure your filters are either replaced or cleaned, depending on the type you use. This simple step can improve air quality and system efficiency.

2. Test Your Thermostat

Check your thermostat to ensure it's functioning correctly. It's a good time to consider upgrading to a smart thermostat, which can offer significant savings on your energy bill by adjusting the temperature when you're not home.

3. Inspect Your Ductwork

Leaky ducts can lose up to 30% of heated air before it reaches your living spaces. Inspect your ductwork for any signs of leaks, and have them sealed. Proper insulation around your ductwork can also go a long way in preserving heat and saving money.

4. Clear Vents and Registers

Make sure all your vents and registers are open and clear of obstructions. Furniture, curtains, or rugs blocking these can restrict airflow, causing your system to run inefficiently.

5. Schedule a Professional Inspection

Perhaps the most important item on your checklist should be a professional inspection. A certified HVAC technician from Sharony HVAC can check your system for any potential issues and perform necessary maintenance to ensure your unit is winter-ready.

6. Consider Your System’s Age

If your heating system is older, it may be time to consider a full system replacement. Newer models are far more efficient and may offer better heating at a lower cost.

7. Prepare for Emergencies

Ensure you have a backup plan in case of system failure. This could mean having space heaters on hand or ensuring your fireplace is in working order.

8. Check Carbon Monoxide Detectors

Winter means your home will be sealed up tight, so it's essential to ensure your carbon monoxide detectors are functioning correctly to detect any dangerous emissions from your furnace.
