Points to keep in mind
- Matching with an older furnace may limit options. Some high-efficiency systems require a variable-speed blower. More on air conditioning installation.
- Utility programs sometimes offer rebates or demand-response incentives for smart thermostats. More on thermostats and controls.
- Incentives are frequently offered for heat pumps. Programs and eligibility rules change, so confirm current details. More on heat pumps.
- Electrical upgrades may be needed. Some homes need panel or circuit changes to support a heat pump and backup heat. More on heat pumps.
- Comfort issues may not be duct-related. Windows, insulation and air sealing also play a role. More on ductwork and indoor air quality.
- 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
- Describe the symptom in plain terms: no heat, weak airflow, short cycling, odd smells, noises or a thermostat that will not respond.
- Note any rooms that are consistently too hot or too cold, which can point to duct or zoning issues.
- 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.
- List times you can be reached and when someone can provide access.
Good questions to ask any provider
- Do you offer a maintenance plan, and what does it include?
- Is my current thermostat location giving accurate readings?
- Which filter rating is appropriate for my equipment?
- Do you recommend sealing, cleaning, redesign, or a combination?
- Is this thermostat compatible with my equipment and wiring?
