Points to keep in mind
- Variable-speed and two-stage furnaces can improve comfort and quietness but cost more upfront. Whether they are worth it depends on your priorities. More on furnace repair and replacement.
- Controls affect efficiency. A thermostat that isn't set up for a heat pump may call for backup heat more often than needed. More on heat pumps.
- Oversizing is a common problem. An oversized system can cool quickly but cycle often, leaving humidity and uneven temperatures. More on air conditioning installation.
- A heat pump may be worth comparing, since it can provide both cooling and heating with one outdoor unit. More on air conditioning installation.
- Heat pumps need correct configuration, especially for auxiliary heat. More on thermostats and controls.
- Ventilation matters in tight homes. Well-sealed houses may benefit from mechanical ventilation. More on ductwork and indoor air quality.
Before you send an inquiry
- 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.
- 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
- What maintenance will any added equipment require?
- How do you protect the outdoor unit from snow and ice?
- Which filter do you recommend for my system?
- Will you replace the line set and indoor coil, or reuse them?
- Did you check for carbon monoxide or a cracked heat exchanger?
