Heating

Furnace care, repairs, and efficiency tips

5 questions
Filter replacement frequency depends on the type:

  • Standard 1-inch filters: Every 1-3 months
  • Pleated 4-inch filters: Every 4-6 months
  • High-efficiency 5-inch filters: Every 6-12 months

Change more frequently if you have pets, allergies, or live in a dusty area.
Most furnaces have a lifespan of 15-20 years. Consider replacement if you're experiencing frequent repairs, rising energy bills, uneven heating, or your system is approaching the 15-year mark. Our team can evaluate your system and help you decide whether repair or replacement makes the most financial sense.
The right furnace size depends on several factors including your home's square footage, insulation levels, window types, and local climate. An oversized or undersized furnace will waste energy and reduce comfort. We perform a detailed Manual J load calculation to recommend the perfect size for your specific home.
Several common issues can cause this:
  • Thermostat issues — incorrect settings or faulty sensor
  • Pilot light out — the ignition source has gone out
  • Dirty air filter — restricting airflow and triggering safety shutoff
  • Duct problems — leaks or disconnections in your ductwork

If the problem persists, call us for a professional diagnosis.
Here are proven ways to reduce your heating costs:
  • Schedule regular maintenance to keep your system running efficiently
  • Seal ductwork to prevent heated air from escaping
  • Upgrade to a programmable or smart thermostat for optimal scheduling
  • Improve insulation in your attic, walls, and around windows

Cooling

AC maintenance, repair, and best practices

5 questions
We recommend annual AC service, ideally in the spring before the summer heat arrives. This ensures your system is running at peak performance and efficiency when you need it most. Regular service also helps catch small issues before they become expensive repairs.
The Department of Energy recommends 78°F when you're home and setting it higher when you're away for optimal energy savings. Each degree you raise saves approximately 3% on cooling costs. A programmable thermostat makes this easy to manage automatically.
Several issues can cause this frustrating problem:
  • Low refrigerant — a leak may have developed
  • Dirty condenser coils — reducing heat transfer efficiency
  • Compressor issues — the heart of your AC system may need repair
  • Thermostat problems — miscalibration or wiring faults

A professional diagnosis can pinpoint the exact cause. Call us for prompt service.
With proper maintenance, most AC units last 15 to 20 years. Regular annual tune-ups, timely filter changes, and prompt repairs can help maximize your system's lifespan and keep it running efficiently throughout its service life.
A good rule of thumb: if the repair cost exceeds 50% of the replacement cost and your system is 10+ years old, replacement is usually the better long-term investment. A new, high-efficiency system can dramatically lower your energy bills and improve your home comfort. We provide honest assessments to help you make the best decision.

Heat Pumps

Efficiency, installation types, and savings

4 questions
Absolutely! Modern cold-climate heat pumps are designed to work efficiently in temperatures as low as -15°F to -20°F, making them an excellent choice for Washington winters. They provide both heating and cooling from a single system, offering year-round comfort and significant energy savings.
Ducted heat pumps use your home's existing ductwork to distribute heated or cooled air throughout the entire house. Ductless mini-split systems provide targeted heating and cooling to individual rooms or zones without requiring ductwork — ideal for additions, garages, or older homes without ducts.
Heat pumps can save 30-50% on energy costs compared to traditional heating and cooling systems. They achieve this remarkable efficiency by transferring heat rather than generating it, using significantly less electricity to maintain comfortable temperatures in your home.
Heat pump maintenance includes:
  • Biannual professional tune-ups (spring and fall)
  • Regular filter changes every 1-3 months
  • Keep the outdoor unit clear of debris, leaves, and vegetation (maintain 2 feet of clearance)

Our maintenance plans make it easy to stay on schedule.

Maintenance

Tune-ups, plans, and preventive care

4 questions
We recommend twice-yearly maintenance: once in spring to prepare your air conditioning system for summer, and once in fall to ensure your heating system is ready for winter. This biannual schedule helps prevent breakdowns during peak seasons.
Our comprehensive maintenance includes:
  • Filter replacement or cleaning
  • Coil cleaning (evaporator and condenser)
  • Refrigerant level check and adjustment
  • Electrical connection inspection and tightening
  • Thermostat calibration and testing
  • Complete safety check including carbon monoxide testing
Yes! Regular maintenance provides significant return on investment by:
  • Preventing costly breakdowns that typically cost 3-10x more than a tune-up
  • Extending equipment life by 5-10 additional years
  • Improving efficiency by up to 25%, lowering monthly energy bills
  • Maintaining manufacturer warranty coverage
Yes! Our maintenance plans include priority scheduling so you get served first during busy seasons, service discounts on any additional repairs, and biannual tune-ups to keep your system running at peak performance year-round. Contact us to learn more about our plans.

The cost varies based on the type of system (furnace, heat pump, AC, etc.), your home's size, and specific installation requirements. We provide free in-home estimates with transparent, upfront pricing so you know exactly what to expect. Schedule your free estimate today.
We charge a small diagnostic fee to thoroughly assess your system and identify the issue. The good news: this fee is applied as a credit toward any repair work we perform. So if you proceed with the repair, the diagnostic is effectively free.
Never. We believe in complete transparency and always provide upfront pricing before any work begins. You'll know the full cost and approve it before we start. No surprises, no hidden charges, no pressure — just honest, straightforward service.
