Q&A

How can improper HVAC sizing affect my home in Bonne Terre?

An improperly sized system, whether too large or too small, is a common issue here. An oversized unit will short-cycle, turning on and off rapidly, which wastes energy, increases humidity, and leads to uneven temperatures in your rooms. An undersized unit will run constantly, struggling to heat or cool your home and driving up your utility bills. Our experts perform detailed Manual J load calculations to determine the perfect size for your home's specific layout and insulation, ensuring efficiency and comfort.

What are the signs of a refrigerant leak in my AC?

In our Missouri climate, a refrigerant leak can leave you without cool air when you need it most. Key signs include your AC blowing warm or lukewarm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing or bubbling sound from the unit, and a sudden spike in your cooling bills. It's important to address leaks quickly, as low refrigerant levels strain the compressor. We use specialized tools to locate and repair leaks, then recharge the system to its proper level.

Can you help me choose a new system that's right for my older Bonne Terre home?

Absolutely. Older homes in our area often have unique challenges like drafty windows or varying insulation levels. We don't just recommend a standard unit; we evaluate your entire home's thermal envelope. Our process includes assessing your ductwork, insulation, and sun exposure to recommend a system that provides consistent comfort without wasting energy. We'll explain all your options, from high-efficiency models to zoning solutions, helping you make an informed decision for your home and budget.
