Lennox Furnace

Exacting precision makes Lennox^® air conditioners among the quietest and most energy-efficient units you can buy.

True comfort is Precise Comfort®

Even on the most humid days, Lennox Precise Comfort^® technology keeps temperatures exactly where you set them, using only the energy that’s needed.

Perfect degree of cool

There’s cool, and there’s perfectly cool. Many Lennox® air conditioners make the distinction with two-stage technology.

Lennox^® air conditioners are amongst the quietest and most energy efficient units on the market. Delivering perfectly precise comfort control, Lennox air conditioners continually make small adjustments in fan speed and cooling output to hold your temperature exactly where you want it. Offering industry-leading efficiencies of up to 26.00 SEER, Lennox air conditioners can help you save hundreds of dollars every year in utility costs. And since some of the units are ENERGY STAR^® certified, they may even qualify you for federal energy tax credits and local utility rebates. In addition, a number of Lennox air conditioners work with iComfort^® S30 and iComfort^® E30 smart thermostats, giving you even more control over your home’s comfort—whether you are at home or away.

What Our Customers Say

Business responded quickly to my inquiry for service (thanks Renee!). Bobby arrived on time, explained everything he was doing, was quick, efficient and stuck to their quote, which was very reasonable BTW. I'm scheduling them for more services and wouldn't hesitate referring them to anyone.UPDATE! we had Lifetime return for dryer duct and vent cleaning, then for AC maintenance. Very happy both times and will continue to use their services. 5 thumbs up!👍👍👍👍👍

What a great company filled with friendly, yet professional people who care about your job from the beginning to end. It starts with Renee who schedules the team to come out. The installers, Nick and Beau were excellent in checking in and communicating every step throughout the day. Electricians Tony and Alex had challenges with our system, but figured it out and voila! We have nice, cool, fresh air filling up our food bank!Then, here came David a few days later to service our furnace. Another excellent employee. We purchased the Premier Club Maintenance Plan and thrilled that we did!

Nick, Beau & Tony did a great job installing our new AC & Furnace. Very professional, friendly & quick install. Nick had quite a job in such a tight space & did a terrific job. Beau even fixed a ducting problem after a previous contractor did a shoddy job. We so Appreciated their attention to detail. Great, professional, informative & fun team & we felt totally confident in their ability. We will definitely recommend them to friends who are looking for new AC. They even installed a much better & easier to use thermostat, set it up for our schedule. And the AC is so cool! Thanks Nick, Beau. & Tony.

We called this company based off all the amazing google reviews and when we met with the company, we instantly knew we contacted the right people. They got us in for an estimate early, they scheduled us for our install the very next week (mind you it’s middle of summer when AC is WA is in high demand). The estimate was straight forward and they also looked into a few other heating questions we had regarding our home that was built a couple years that we think the builder didn’t install the best way.. I could go on and on. This seems like such a great company that truly cares about their people and their customers. We are excited to CHILL in our new AC that will be installed by this amazing company. 🙂 we have our install next week and I will submit another review after but let me tell you, from this point, we have had a great experience!! We worked with Robert who gave us our estimate and he is awesome!!
