Frequently Asked Questions

Do you provide service throughout Oakland County?

Absolutely. We service all 61 Oakland County municipalities, from Royal Oak to Clarkston. Our strategic routing and multiple service vehicles ensure our emergency response times remain within the 25–45 minute range across the entire county.

What are your Oakland County response times?

Emergency response times range from 25–30 minutes in the Southern communities (Royal Oak, Ferndale) to 35–45 minutes in the Northern and Western areas (Clarkston, Milford). We maintain genuine 24/7/365 availability with zero surcharges.

Why do lakefront properties need special HVAC attention?

Oakland County has over 1,000 inland lakes. Properties near water (like those in Commerce, White Lake, or Orchard Lake) face elevated humidity. We specialize in AC systems with enhanced dehumidification, duct sealing, and dedicated whole-home dehumidification systems to prevent mold and moisture challenges.

What does furnace installation cost in Oakland County?

Installation costs vary significantly by home size and age. Compact homes (1,000–1,500 sq ft) generally range from $3,500–$5,500. Larger properties (2,500–3,500+ sq ft) range from $5,500–$9,000. Upgrading aging 60–70% AFUE furnaces (common in older homes) provides significant utility savings and often pays back in 6–8 years.
