best HVAC company in Kirkland

When winter hits Kirkland, a reliable furnace isn't a luxury—it's a necessity. At Frost HVAC, we specialize in furnace installation and replacement for both residential and commercial properties. Whether your old unit has finally given out or you're looking to upgrade to a more energy-efficient model, our certified technicians guide you through every step.

We work with top brands like Trane and Bryant to offer systems that balance performance with affordability. Our process begins with a thorough assessment of your home's size, insulation, and existing ductwork to recommend the perfect size and efficiency rating. We then handle the complete installation, including safe removal of your old furnace, all gas and electrical connections, and a full system test to ensure optimal operation.

Why choose us? Because we don't cut corners. We pride ourselves on leaving no mess behind, providing accurate solutions the first time, and finishing on schedule. Plus, with our 2-year labor warranty, you can rest easy knowing we stand behind our work. Call us today to schedule a consultation and get a fair, honest quote for your new furnace.

Heat pumps are the smart choice for year-round comfort in Kirkland, offering both heating and cooling in one energy-efficient package. At Frost HVAC, we are proud specialists in Mitsubishi heat pump installation—featuring some of the most efficient equipment on the market. Our technicians are trained in the latest ductless and ducted heat pump technologies, ensuring seamless integration with your existing HVAC setup.

The process starts with a home evaluation: we assess your layout, insulation, and specific heating/cooling needs. For homes without ductwork, we often recommend ductless mini-splits, which allow for zone control and significant energy savings. Our team handles everything from mounting indoor and outdoor units to refrigerant line installation and electrical hookups. We also work with Nest thermostats, preserving your smart home setup if desired.

We've successfully completed heat pump installations in challenging locations—like crawlspaces and tight attics—without compromising on quality or safety. All our installations come with a 10-12 year manufacturer warranty and our 2-year labor warranty. Contact Frost HVAC to learn how a heat pump can lower your utility bills while keeping you comfortable all year long.

Nothing beats the relief of central air during the hot summer months in Kirkland. Frost HVAC provides professional air conditioning installation services for homeowners who want reliable, efficient cooling. Whether you're building a new home or replacing an outdated, struggling AC unit, we deliver solutions tailored to your space and budget.

Our team begins with a detailed load calculation to determine the correct AC size for your home—too small and it will run constantly without cooling effectively; too large and it will short cycle, wasting energy. We then present options from leading brands like Trane and Bryant, explaining efficiency ratings (SEER), noise levels, and smart features. Installation includes placing the condenser unit, connecting refrigerant lines, integrating with your furnace's air handler, and testing the entire system for leaks and proper airflow.

We're known for working quickly without sacrificing quality—often completing an AC install in 1-2 days. Plus, we clean up thoroughly, so you can enjoy your cool home without any mess. With fair, upfront pricing and a 2-year labor warranty, we make upgrading your AC stress-free. Ready to beat the heat? Give us a call for a complimentary estimate.
