When to Hire a Heating & Cooling Companie

Schedule HVAC service when your system isn't heating or cooling effectively, making unusual noises, cycling frequently, or causing high energy bills. For replacement, systems over 15-20 years old often justify upgrading for efficiency gains. Ideally, schedule maintenance in spring (for AC) and fall (for heating) before peak season demand.

Questions to Ask Before Hiring

• Are your technicians EPA 608 certified for refrigerant handling?
• How do you determine the correct system size for my home?
• Do you perform a Manual J load calculation for new installations?
• What brands do you install, and why do you recommend them?
• What warranties come with new equipment and your labor?
• Do you offer maintenance plans, and what do they include?
• Will you inspect and seal ductwork as part of installation?

Red Flags to Watch For

• Sizes new system based on old unit without calculating actual needs
• Quotes system replacement over the phone without inspection
• Dramatically lower bid than competitors (likely cutting corners)
• Pressures you to replace when repair is reasonable
• Won't provide written warranty information
• No EPA certification for technicians
• Doesn't discuss ductwork condition for new installations

Cost Considerations in St. Louis

HVAC service calls in St. Louis run $75-$150 plus parts. New AC units cost $4,000-$8,000 installed; furnaces run $3,000-$6,000. Complete system replacement (AC + furnace) typically costs $8,000-$15,000+ depending on efficiency rating and home size. High-efficiency systems cost more upfront but can reduce energy bills 20-40%. Don't choose based on price alone; improper installation wastes efficiency and shortens equipment life.
