Points to keep in mind
- Humidifiers need maintenance. Whole-house humidifiers should be cleaned and checked regularly. More on ductwork and indoor air quality.
- Permits are typically required for furnace replacement in many jurisdictions. Ask the contractor whether they obtain it. More on furnace repair and replacement.
- Oversizing is a common problem. An oversized system can cool quickly but cycle often, leaving humidity and uneven temperatures. More on air conditioning installation.
- Age and repair history matter. A furnace that needs repeated repairs or a major component may be a candidate for replacement rather than another fix. More on furnace repair and replacement.
- Smart features depend on Wi-Fi and accounts. Consider privacy and connectivity. More on thermostats and controls.
- Sizing should be calculated. A properly performed load calculation, often called a Manual J, considers your home's insulation, windows and layout. More on furnace repair and replacement.
Getting ready to reach out
- 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.
- If you smell gas or suspect carbon monoxide, leave the home and contact your gas utility or emergency services first, before sending any inquiry.
- Note any rooms that are consistently too hot or too cold, which can point to duct or zoning issues.
- Say whether you own or rent, and whether the home has a basement, crawl space or attic access to the equipment.
Good questions to ask any provider
- Did you check for carbon monoxide or a cracked heat exchanger?
- How do you check refrigerant levels?
- Do you clean the indoor coil, or only inspect it?
- Can you configure it correctly for my heat pump or multi-stage system?
- What does your tune-up checklist include?
