Why Northwind

The stuff that actually matters when your system is down

We're not the biggest shop in town and we're not trying to be. We're the one that shows up when we said we would and charges what we quoted.

  • Flat-rate pricing. You approve a price, not an hourly meter running while a tech looks for parts.
  • The same technicians. W-2 employees who've been here for years, not a rotating cast of subcontractors.
  • Honest repair-vs-replace advice. If a $200 part buys you three more years, we'll tell you that.
  • Real 24/7 dispatch. Nights, weekends and holidays reach a person, not a voicemail box.

How fast a tech gets to your door

Northwind emergency

Emergency response measured across no-heat and no-cool dispatches over the last 12 months. Non-emergency work is typically scheduled same or next day.

How it works

Three steps, no runaround

1

Call or request online

Tell us what the system is doing. We'll book a window that works — same or next day for most calls, immediately for emergencies.

2

We diagnose and quote

A licensed technician finds the actual problem and gives you a flat price to fix it. You decide before any work starts.

3

We fix it and follow up

Most repairs are done the same visit. We check the whole system before we leave and send a written summary of what we did.

In their words

What neighbors say after we leave

Our AC quit on a Friday night in July. Northwind had someone out in under an hour and we had cold air back before the kids' bedtime. Told us the price before they touched anything.

Marcus R.Round Rock

They replaced a 20-year-old furnace and actually did a load calculation instead of just selling me the biggest unit. House is more even than it's ever been.

Diane K.Georgetown

We've been on their maintenance plan for three years. No surprise breakdowns, and the technician is the same guy every visit who knows our system.
