Will they size the system properly?

Replacement equipment should be sized with a load calculation, not by matching the old unit.

Is the model rated for cold climates?

Ask for a cold-climate heat pump that keeps its capacity at low temperatures, and whether a backup heat source is recommended.

Do they handle Xcel Energy rebates?

Xcel Energy and the state offer rebates on high-efficiency furnaces and heat pumps. Ask the contractor to include eligible rebates in the quote.

Furnace, AC and heat pump replacements need a mechanical permit in Longmont. Confirm it is in the price.
