If your heater is blowing cold air, making strange noises, turning on and off frequently, or causing your energy bill to spike, it’s time to have it checked. Even smells like burning dust could signal the need for a service visit.

Yes. Many issues can be prevented or solved with a thorough heater tune-up. At Nalk, we perform safety checks, cleaning, and efficiency testing as part of our maintenance visits. If we spot something needing repair, we’ll explain it clearly and let you decide next steps.

We respond promptly, often within 24 hours during normal demand. Our technicians arrive ready to diagnose and repair most common problems in a single visit. In busy winter months, we prioritize customers with no heat or safety concerns first.

Yes. We work with all major brands and system types, including gas furnaces, electric heaters, and high-efficiency units. Whether your system is 5 years old or 25, we’ve seen it—and fixed it.

Once a year is best. Ideally in early fall before the cold hits, but January and February are still smart months to catch issues before they become emergencies.

Yes, and proudly so. Nalk is based right here in Fresno. We live where we work, and that means treating our customers like neighbors. No national chains. No corporate gimmicks.

Never. Our job is to give you options and honest advice. If we can safely repair it, we will. If replacement makes more sense long-term, we’ll explain why—but the decision is always yours.

We do. Our twice-yearly service program keeps your system running efficiently and extends its lifespan. Members also get priority scheduling and service discounts.
