Frequently Asked Questions

How do I know if my HVAC system needs repair or replacement?

Different types of HVAC systems have varying lifespans. In general, if your system is getting close to the end of its expected lifespan, a replacement may be a better choice. We also recommend replacement if your system requires frequent repairs, is no longer energy efficient, or if it is unable to effectively heat or cool your home.

What should I do if I’m experiencing a leak?

If you have a leak, shut off the main water to your home to prevent further damage. Then, use towels or buckets to remove as much water as possible, and open windows or use fans to encourage drying. Then, call our team for emergency leak detection and repairs.
