How do I prepare my HVAC system for winter?

If you’re a homeowner in Monett, Missouri, or anywhere across Southwest Missouri, there’s no better time than now to get your heating, ventilation, and air conditioning system ready to handle the cold season. At Davis & Son HVAC & Plumbing, we’ve helped local families keep their homes warm, efficient, and comfortable through the Missouri winters, and today I want to walk you through the most important steps—from your air filter replacement frequency to thermostat calibration—so you’re fully prepared.

Why your winter prep matters in Monett

Here in Monett (Barry County) and the broader Southwest Missouri region, we don’t just get mild chilly nights. Our climate features cold winters, sometimes dipping near 9 °F design temperatures per local building code. At the same time, summer heat and humidity tax your air-conditioning system so it’s already been working hard. That means your system may be more worn than you think.

Because of that seasonal stress, a sound HVAC maintenance schedule matters: regular tune-ups, filter changes, and duct inspections all contribute to reliable performance, lower energy bills, and improved indoor air quality.

Step 1 – Air filter replacement frequency: what to know

One of the simplest yet most impactful maintenance tasks is changing your air filter. Whether you use a pleated filter, a HEPA-style filter, or basic fiberglass, the filter lifespan varies depending on usage, home environment (pets, dust, pollen), and system demand.

For many homes, a standard filter might need changing every 60–90 days in typical conditions—but if you have pets, allergies, or a high-dust environment, you might need every 30–45 days.
If you use higher-efficiency filters (MERV ratings of 8, 11, or higher), refer to the manufacturer’s filter change guidelines.
Since Southwest Missouri weather includes spring and summer pollen loads and fall/winter indoor air closure, your air filter replacement schedule is crucial for good air quality and allergy prevention.

Here in Monett, we often see homeowners overlook their AC filter replacement at the end of summer—and then they enter winter with reduced airflow and efficiency. That’s a missed opportunity for energy savings and better comfort.

Step 2 – Scheduling full HVAC maintenance: inspection & cleaning

Beyond filters, your HVAC system deserves a seasonal check-up. For example:

Check the heating contractor side: furnace inspection, thermostat calibration, and safety controls.
If you still use your AC during mild days, clean the coil (coil cleaning) to maintain efficiency.
Inspect ductwork for leaks and proper insulation—important because poor ducts increase energy consumption and worsen indoor air pollution.
Review thermostat calibration to ensure consistent comfort.
Consider indoor air quality improvements such as better ventilation systems or air purifiers to reduce dust mites, pet dander, pollen, and particulate matter.

For Monett and surrounding towns, a good HVAC maintenance frequency is at least once per year—ideally in autumn before heavy furnace use.

Step 3 – Specific tips for Monett and Southwest Missouri homeowners

Since you’re local to Monett and Southwest Missouri, here are region-specific notes:

Winter nights can drop sharply after mild days—don’t wait for the first freeze to service your system.
Our humid summers and stormy springs put stress on AC units—have both heating and cooling components checked.
Monett’s building codes adopt the International Mechanical Code and Residential Code, requiring professional installation and proper duct modifications.
The state also follows the International Energy Conservation Code (IECC), ensuring high efficiency and reduced energy consumption.
If your home is older, check insulation and air leaks. Davis & Son can advise on system sizing and filter types that match your home’s construction.

Step 4 – Filter types, sizes, and efficiency ratings

When replacing filters and establishing your air filter replacement frequency, it helps to know the basics:

Measure your existing filter slot for correct filter dimensions (e.g., 16×25×1, 20×25×4).
Choose the right MERV rating: MERV 8 handles dust and pollen; MERV 13 handles pet dander, smoke, and fine particles.
HEPA and pleated filters improve home air quality, but always confirm compatibility.
If your filter lifespan is past due, airflow drops and system strain increases, leading to higher energy bills.

Step 5 – Energy efficiency and sustainability

While you prepare for winter in Monett, remember that proper maintenance supports both comfort and sustainability:

A clean filter, leak-free ducts, and a calibrated thermostat all reduce energy use.
Missouri’s HVAC efficiency standards now require higher SEER ratings for new equipment.
Maintaining your system early helps prevent emergency repairs and lowers your carbon footprint.
Davis & Son can help you achieve energy conservation, longer equipment life, and reliable performance.
