Points to keep in mind
- Defrost cycles are normal. In cold, humid conditions the outdoor unit periodically defrosts, which can produce steam and brief noise. More on heat pumps.
- Carbon monoxide safety is essential. Working CO alarms are recommended in homes with fuel-burning appliances, regardless of the furnace's condition. More on furnace repair and replacement.
- Permits are typically required for furnace replacement in many jurisdictions. Ask the contractor whether they obtain it. More on furnace repair and replacement.
- Warranty registration often has a deadline. Ask who handles it and keep the paperwork. More on air conditioning installation.
- Utility programs sometimes offer rebates or demand-response incentives for smart thermostats. More on thermostats and controls.
- Air purifiers vary widely. Ask how a device works and what independent testing supports its claims. More on ductwork and indoor air quality.
What to have ready
- Note any rooms that are consistently too hot or too cold, which can point to duct or zoning issues.
- If you smell gas or suspect carbon monoxide, leave the home and contact your gas utility or emergency services first, before sending any inquiry.
- List times you can be reached and when someone can provide access.
- Mention what you have already checked, such as the thermostat batteries and settings, the filter and the breaker.
- Describe the symptom in plain terms: no heat, weak airflow, short cycling, odd smells, noises or a thermostat that will not respond.
Good questions to ask any provider
- Did you check for carbon monoxide or a cracked heat exchanger?
- What warranties cover the equipment and the labor, and who registers them?
- Will you perform a load calculation, and can I see the result?
- Would a humidifier, dehumidifier or ventilation system help my home?
- How do you check refrigerant levels?
