7 Common HVAC Mistakes Ralston Homeowners Should Avoid

Whether it’s a freezing Nebraska winter or a scorching summer in Ralston, your HVAC system works hard to keep your home comfortable. But small mistakes can lead to big problems — higher bills, breakdowns, or even full system failure.

Here are seven of the most common HVAC mistakes we see Ralston homeowners make — and what to do instead:

1. Ignoring Regular Maintenance

Skipping seasonal maintenance causes efficiency to drop and repairs to pile up. Book a routine HVAC tune-up at least twice a year — once before cooling season and once before heating season.

2. Forgetting to Change Air Filters

Clogged filters restrict airflow, overwork your system, and worsen indoor air quality. Change your furnace or AC filter every 1–3 months, especially during high-use months.

3. Blocking Vents and Registers

Furniture, rugs, and curtains can obstruct airflow and force your system to work harder. Keep vents clear to ensure even heating and cooling throughout your home.

4. Setting Thermostats Too Low (or Too High)

Extreme thermostat settings don’t cool or heat your home faster — they just waste energy. Use a smart thermostat to set efficient, comfortable schedules.

5. DIY Repairs Without Training

Trying to fix HVAC problems without experience can lead to more damage, safety risks, and voided warranties. Always call a professional for furnace repair or AC issues.

6. Neglecting Duct Cleaning and Sealing

Leaky or dirty ductwork reduces airflow and indoor air quality. Schedule professional duct cleaning to improve system efficiency and remove built-up dust and allergens.

7. Waiting Too Long to Replace an Old System

If your HVAC system is 15+ years old, it may be costing you more in energy and repairs than a new system would. Ask us about energy-efficient upgrades and available rebates.
