Common Questions
How can I tell if my San Marcos home's HVAC system is the wrong size?
Signs include rooms that are never comfortable, frequent short cycling (turning on and off rapidly), and unusually high energy bills. An oversized system cools or heats too quickly without properly dehumidifying, while an undersized one runs constantly. J A Fergus can perform a professional load calculation to determine if your current system is sized correctly for your home.
My heat pump isn't heating as well as it used to. What's a common cause in our area?
A frequent issue in San Marcos is a loss of refrigerant charge or a buildup of dirt on the coils, which severely reduces a heat pump's efficiency. Regular professional maintenance, including checking refrigerant levels and cleaning the outdoor unit, is crucial. J A Fergus offers tune-up services specifically designed to keep your heat pump running at peak performance year-round.
What should I consider before replacing my old HVAC system in San Marcos?
The most critical factor is proper sizing based on a new Manual J load calculation, not just matching the old unit's capacity. Our climate and your home's insulation, windows, and layout all affect the needed size. J A Fergus will assess your home thoroughly to recommend a system that provides optimal efficiency, comfort, and longevity for our local conditions.
