Frequently Asked Questions

Why isn’t my HVAC system cooling or heating properly?

If your system isn’t as efficient in cooling or heating your space as before, the problem could be something as simple as a dirty air filter, blocked vents, or low refrigerant. It may also be something serious, such as leaky ductwork, a faulty thermostat, or frozen coils. A professional inspection can quickly find the issue and get your comfort back on track.

Most HVAC systems should be checked by professional technicians at least once a year, ideally twice. Scheduling a tune-up at the start of the summer season for cooling and again in the fall for heating helps keep your system efficient, reliable, and less likely to break down when you need it most.

A good rule of thumb is every 1–3 months, but it depends on your filter type, home size, whether you have pets, and if any member in the family has allergy concerns. Replacing your filter regularly keeps airflow strong, reduces strain on the system, and improves the air you breathe indoors.

Small maintenance can go a long way when it comes to HVACs. To help lower the power consumption when using HVAC, you may replace filters regularly, schedule annual tune-ups, and ask a technician to seal any leaks in your ductwork promptly. Using a thermostat can also reduce energy waste, and if your system is older, upgrading to a high-efficiency unit can bring even greater savings.

Yes! Heating and cooling issues don’t wait for business hours. Our team is available for 24/7 emergency repair service, so you’re never left without comfort when you need it most.

There’s no one-size-fits-all answer. The right system depends on your home’s square footage, insulation, windows, layout, and even lifestyle habits. Our comfort specialists perform a detailed load calculation to ensure your system is perfectly sized for efficiency and comfort.

Yes! As a Trade Ally with local utilities such as Puget Sound Energy, Snohomish PUD and Seattle City Light, we can connect you with rebates and incentives that lower the cost of upgrading your HVAC system.

With proper maintenance, most systems last 12–20 years. Air conditioners and heat pumps usually last 12–15 years, while furnaces often reach 20 years or more. Annual tune-ups are the best way to extend your system’s lifespan and avoid costly repairs.
