HVAC FAQs - Washougal, WA

The cost of a new HVAC system typically ranges from $5,000 to $15,000+, depending on system type, home size, efficiency rating, and installation complexity. Heat pumps and ductless systems may vary based on layout and zoning needs.

Most HVAC systems last 12–20 years with proper maintenance. Furnaces and air conditioners average around 15 years, while heat pumps often last 10–15 years.

If your system is over 10–15 years old, needs frequent repairs, or uses outdated refrigerant, replacement is often more cost-effective than continued repairs.

HVAC systems should be serviced once per year, ideally in Spring for cooling systems and Fall for heating systems. Regular maintenance improves efficiency and extends system life.

System size depends on square footage, insulation, layout, and climate. A professional load calculation ensures the system isn't oversized or undersized, which can cause inefficiency and comfort issues.

A heat pump transfers heat instead of generating it. It provides both heating and cooling, making it an energy-efficient option for many homes.

Yes. Modern heat pumps are designed to work efficiently even in colder climates, especially newer cold-climate models.

Ducted systems use air ducts to distribute air throughout the home. Ductless systems (mini-splits) heat or cool individual rooms without ductwork, offering zoning and energy savings.

Ductless systems are ideal for homes without ductwork, room additions, or areas with uneven temperatures. They're highly efficient and allow room-by-room temperature control.

Most installations take 1–2 days, depending on system type, ductwork requirements, and home layout.

Common causes include low refrigerant, dirty air filters, thermostat issues, or outdoor unit problems. A professional inspection can quickly diagnose the issue.

This can be caused by thermostat problems, dirty filters, ignition issues, or electrical faults. Regular maintenance helps prevent these problems.

Air filters should be changed every 1–3 months, depending on filter type, pets, allergies, and system usage.

Yes. High-efficiency systems reduce energy consumption, lowering monthly utility bills and often qualifying for rebates or incentives.

A higher SEER rating means better efficiency. Most homeowners choose systems rated 14–18 SEER, balancing cost and energy savings.

Yes. Proper HVAC systems help filter dust, allergens, and pollutants. Optional upgrades include air purifiers, humidifiers, and advanced filtration.

Unusual noises can indicate loose components, motor issues, airflow problems, or worn parts. Ignoring noises can lead to larger repairs.

If repair costs exceed 30–40% of replacement cost, or the system is nearing the end of its lifespan, replacement is usually the better investment.

Schedule annual maintenance, upgrade to a high-efficiency system, seal duct leaks, and use a programmable or smart thermostat.

Yes. Professional installation ensures proper sizing, safety, warranty protection, and long-term system performance.
