Points to keep in mind
- Incentives are frequently offered for heat pumps. Programs and eligibility rules change, so confirm current details. More on heat pumps.
- Operating cost depends on local electricity and gas prices. A contractor can help compare scenarios, but rates change. More on heat pumps.
- Get comparable quotes. Make sure bids specify the same equipment tier, scope and included items. More on air conditioning installation.
- Duct condition affects results. Leaky or undersized ducts can undermine even a well-chosen system. More on air conditioning installation.
- Cold-weather performance varies by model. Ask for the unit's rated capacity at low outdoor temperatures, not just its nominal size. More on heat pumps.
- Low refrigerant usually means a leak. Repeatedly topping off refrigerant without finding the leak is a short-term solution. More on AC Tune-Ups and Maintenance.
What to have ready
- Note any rooms that are consistently too hot or too cold, which can point to duct or zoning issues.
- List times you can be reached and when someone can provide access.
- Say whether you own or rent, and whether the home has a basement, crawl space or attic access to the equipment.
- Note the make, model and approximate age of your furnace, air conditioner or heat pump. The label is usually on the side of the unit or inside a panel.
- Mention what you have already checked, such as the thermostat batteries and settings, the filter and the breaker.
Good questions to ask any provider
- Would zoning help my home, or is there a simpler fix?
- Will you perform a load calculation, and can I see the result?
- Do you install thermostats I've already purchased?
- What warranties come with the equipment and your labor?
- What exactly failed, and can you show me the part or reading?
