5 Easy Steps to Prepare Your HVAC Unit for the Winter

As the seasons begin to shift and cooler weather approaches, homeowners have a brief window of opportunity to save on HVAC costs. By turning off the system temporarily and letting in the fresh autumn air, you not only enjoy natural ventilation but also give your unit a short break. However, this transitional period won’t last long soon, it will be time to switch on the heat.

So, the big question is: Is your HVAC system ready for the upcoming winter?

If you haven’t already started preparing your system, now is the time. Routine preventive maintenance is the most effective way to keep your HVAC system in peak condition, help it adjust to the changing temperatures, and avoid unexpected breakdowns. Regular check-ups can also extend your system's lifespan and minimize the risk of costly emergency repairs.

To make the process simple, we’ve compiled a list of 5 easy steps that every homeowner can follow to prepare their HVAC system for the winter season, especially if you're considering a heater replacement in Roanoke, VA.

1. Power Down Your System

Before you begin any maintenance task, safety comes first. Always ensure that your HVAC system is completely powered down. Turn off the unit from the main switch and wait for the blower to stop running before inspecting or working on any components.

This precaution protects you from electrical shocks and prevents any accidental start-ups while you're working on the system.

2. Replace the Air Filters

Replacing the air filters is one of the simplest yet most effective maintenance tasks that you can perform on your own. Dirty or clogged filters are one of the leading causes of reduced HVAC efficiency and rising energy bills. When filters become blocked, the system has to work much harder to maintain indoor temperature, which leads to increased energy usage and wear and tear.

Most HVAC manufacturers recommend changing the air filters every 30 to 60 days so if you haven’t changed yours recently, now is the perfect time. Fresh filters not only improve airflow but also enhance indoor air quality by trapping dust, pollen, and other allergens.

3. Run a Sound Check

Your HVAC system is designed to operate quietly in the background. If it begins to make strange or loud noises such as rattling, banging, or squealing this is a red flag.

Unusual sounds are often the first sign of a mechanical issue within the unit. Loose parts, worn-out components, or internal obstructions could all be culprits. Instead of ignoring the noise and hoping it goes away, it’s best to call a certified HVAC technician in Roanoke, VA to conduct a thorough inspection and fix the issue before it escalates.

4. Look for Signs of Moisture

Excess moisture is another sign that your HVAC system might not be functioning properly. If you notice condensation on your windows or dampness near any part of the system, this could indicate a refrigerant leak or a drainage issue.

Unchecked moisture buildup can lead to mold growth, poor indoor air quality, and even structural damage. It's important to have a technician evaluate and repair any moisture-related issues immediately to avoid bigger problems during the winter months.

5. Check the Room Temperature Settings

The thermostat acts as the brain of your heating system. It controls the temperature settings and signals your HVAC unit when to turn on or off. Before winter begins, make sure your thermostat is calibrated correctly and working efficiently.

Try setting a specific temperature and see how evenly it’s distributed throughout your home. If certain rooms feel colder or warmer than others, or if the system cycles on and off more frequently than usual, there may be a problem with the thermostat or the HVAC unit itself.

Smart thermostats are a great upgrade to consider they offer improved control, energy-saving options, and the convenience of remote access.
