We’re always here to help you make the best decisions for your home. Use these tips to keep your system running safely, efficiently, and reliably year-round.
Check monthly and replace every 1–3 months. Clean filters keep airflow strong, energy bills low, and air quality healthy.
Remove leaves, snow, or debris and keep 2 feet of clearance around your AC or heat pump for best performance.
Vacuum and dust your supply and return vents, and make sure they’re open and not blocked by furniture or rugs.
Replace furnace or air-return filters every 1–3 months to trap dust, pollen, and allergens before they circulate.
Use exhaust fans when cooking or showering, and consider an HRV/ERV system to bring in fresh outdoor air year-round.
Keep indoor humidity between 30–50%. Too high causes mold; too low causes dry air and dust. Use humidifiers or dehumidifiers as needed.
Vacuum, dust, and wash bedding often. Choose low-VOC cleaning and home products to reduce chemical pollutants.
Add a high-efficiency air purifier or upgrade to a media or UV filtration system for deeper contaminant removal.
Leaky ductwork can waste a large share of the air your system produces, driving up energy bills and creating hot and cold spots. Sealing and insulating your ducts improves airflow, comfort, and efficiency, and helps your equipment last longer. If some rooms never seem to get comfortable, ask us about a duct evaluation.
