Hiring for HVAC service or replacement
Heating and cooling quotes are hard to compare because equipment, efficiency and installation quality all vary. A few questions make the difference clear.
What to know
- Sizing matters
- A properly sized system is based on a load calculation for your home (often called a Manual J), not just the size of the old unit.
- Compare equipment fairly
- Quotes should list brand, model numbers and efficiency ratings (such as SEER2 for cooling). Look up the model numbers.
- Installation details
- Ductwork changes, thermostat, permits, refrigerant line sets and removal of old equipment should be listed.
- Refrigerant work
- Technicians handling refrigerant must be EPA Section 608 certified.
- Maintenance plans
- A yearly service plan can be worth it, but read what it includes and whether it auto-renews.
Questions to ask the contractor
- Did you do a load calculation to size this system?
- What are the exact model numbers and efficiency ratings?
- Are rebates or tax credits available, and will you help with the paperwork?
