Call Us to Schedule Service or Request a Quote

The fastest way to get your heating or cooling situation handled is a phone call. When you call (707) 892-4623, we gather a few details about your system and what is going on, and we give you honest pricing before any work begins. Same-day availability is often possible for urgent situations, and we offer emergency response for no-heat and no-cool calls that cannot wait.

We do not believe in vague estimates or surprise charges. You will know what the work involves and what it costs before we start anything.

Business Hours

We are available every day of the week, including weekends and holidays, during the following hours:

  • Monday through Sunday: 6:00 AM to 8:30 PM

For urgent heating and cooling situations outside these hours, call us anyway. We take emergency calls seriously and will do our best to get someone to you.

What to Have Ready When You Call

Getting your appointment scheduled goes faster when you have a few details on hand. It helps to know:

  • The type of system you have (central AC, furnace, heat pump, mini-split, or other)
  • The approximate age of the equipment, if you know it
  • What the system is doing or not doing, such as not cooling, blowing cold air, making noise, or not responding to the thermostat
  • Whether the situation is urgent or you are planning ahead

You do not need all of this to call. We will ask the right questions to get the full picture.

Who We Serve

No matter what's going wrong with your heating or cooling, we are set up to help. We work with:

  • Homeowners dealing with a broken or underperforming system
  • Landlords and rental property owners who need reliable, timely service
  • Property managers overseeing multiple units across the area
  • Small business owners and commercial clients who need climate control they can count on

We live and work in this community, and our work shows it. When you call, you are reaching someone who knows Windsor, knows Sonoma County, and treats your property with care from the first visit to the final walkthrough.

What We Handle

From aging systems to brand-new installs, we cover the full range of residential and commercial HVAC work. A few of the most common reasons people call us:

  • AC not cooling or stopped working entirely
  • Furnace blowing cold air or not igniting
  • Heat pump running but not heating or cooling
  • First-time AC or ductless mini-split installation
  • Full system replacement when repair no longer makes sense
  • Wildfire-smoke air filtration upgrades (MERV-13 and higher)
  • Seasonal tune-ups and maintenance before summer or winter
  • Emergency no-heat and no-cool situations

Work is performed by qualified HVAC technicians who explain what they find before any repair begins. We protect your floors and finishes while we work, and we leave the space clean when we are done.
