Regular HVAC maintenance is essential for Milwaukee homeowners facing Wisconsin's extreme seasonal temperatures. A comprehensive maintenance routine prevents costly breakdowns, extends equipment life, and keeps your energy bills under control. Follow this ultimate checklist to keep your heating and cooling systems running efficiently year-round.

Monthly Maintenance Tasks

Check and Replace Air Filters

Inspect your HVAC air filters monthly and replace them every 1-3 months depending on usage, pets, and allergies. Clean filters improve air quality, reduce energy consumption, and prevent system strain. This simple task is the most important thing you can do for your HVAC system.

Inspect Thermostat Operation

Test your thermostat monthly to ensure it's responding correctly and maintaining accurate temperatures. Replace batteries in battery-powered models and clean dust from the unit. Consider upgrading to a smart thermostat for better efficiency and control.

Seasonal Maintenance Tasks

Spring: Prepare Your Air Conditioner

Before Milwaukee's summer heat arrives, clean debris from around your outdoor AC unit, remove the winter cover, and test the system. Schedule professional maintenance with Tony's Heating & Air to check refrigerant levels, clean coils, and ensure optimal performance.

Fall: Prepare Your Heating System

Before Wisconsin's first freeze, test your furnace, check for strange noises or odors, and ensure all vents are clear. Professional pre-winter maintenance catches potential problems before they cause cold-weather emergencies.

Quarterly Maintenance Tasks

Clean Vents and Registers

Every three months, vacuum all supply and return vents throughout your Milwaukee home. Remove vent covers and clean inside the ducts as far as you can reach. This improves airflow and indoor air quality.

Inspect Outdoor Units

Check your outdoor AC condenser and heat pump for debris, vegetation growth, and damage. Maintain at least two feet of clearance around the unit for proper airflow. Trim nearby bushes and remove leaves or grass clippings.

Test Carbon Monoxide Detectors

Test all CO detectors quarterly and replace batteries as needed. These devices provide critical protection against furnace malfunctions that could endanger your family.

Annual Professional Maintenance
