HVAC Frequently Asked Questions

Warm air from the vents, weak airflow, ice on the refrigerant lines, short cycling, and higher than usual energy use are all common signs that an AC system should be inspected. A diagnostic visit helps identify the specific cause.

Common heating issues include a furnace that will not ignite, short cycling, uneven heat, weak airflow, and rising gas use. An inspection can pinpoint which one applies to your system.

Maintenance is appropriate before each season — cooling tune-ups before summer and heating tune-ups before winter. Homes with heavy use or pets may also benefit from more frequent filter changes.

A repair fixes a specific problem that has already occurred. Replacement trades the cost of ongoing repairs for a new system, which often makes sense when equipment is aging or a major component has failed.

A service visit typically includes an inspection of the relevant equipment, testing of the controls and airflow, and a clear explanation of what was found along with the available options.

Common airflow concerns include leaky or disconnected ducts, unbalanced supply runs, crushed ductwork, and a clogged filter. These can cause some rooms to run hot or cold.

A short description of the symptom, when it started, the type of equipment, and the thermostat setting are all helpful. Photos of the equipment and any error codes are also useful.
