The time required for a heat pump installation depends on the complexity of the system and the condition of your existing ductwork. On average, a standard heat pump installation takes about one to two days.
There are several signs that your heat pump may need repairs. If you notice weak airflow, inconsistent heating or cooling, or strange noises coming from the unit, it’s time to have it inspected. Increased energy bills without a clear reason can also signal a problem.
The decision to repair or replace a heat pump depends on the unit’s age and the extent of the damage. If your heat pump is over 10–15 years old and requires frequent repairs, replacing it might be more cost-effective in the long run.
To keep your heat pump running efficiently, it’s recommended to schedule maintenance at least once a year. Ideally, you should have it checked in the spring before the cooling season and in the fall before the heating season.
A heat pump installation involves several key steps. First, the technician will assess your home’s heating and cooling needs and select the right size and type of heat pump. The old system, if applicable, will be removed, and the new unit will be installed.
