It depends on your home’s layout, budget, and cooling needs. Ductless mini-split systems are ideal for homes without existing ductwork, as well as for additions and renovations. They’re energy-efficient, easy to install, and allow for zoned comfort. Central AC, on the other hand, works best for whole-home cooling if you already have ductwork in place. It’s often more affordable for larger spaces, but can be less efficient if your ducts aren’t well-maintained. Our team can help you determine which system is best for your home.
A rotten egg smell usually means there’s a gas leak nearby, especially if you use natural gas for heating. It’s a serious safety concern. Leave your home immediately and call your gas provider or a professional. If it’s coming from your AC and you don’t use gas, it could be a dead animal in the ductwork or a mold issue. Either way, call an HVAC expert to inspect the system right away.
This can happen for several reasons: dirty air filters, low refrigerant levels, a malfunctioning thermostat, or a frozen evaporator coil. Sometimes, it might be an electrical issue with the unit’s compressor or motor. Regular maintenance can prevent many of these problems, but if it happens suddenly, having one of our certified technicians diagnose the issue is best.
Both options offer efficient heating and cooling. A ductless mini-split is ideal for homes without ductwork, individual rooms, or homes that need zoned comfort. A heat pump is ideal for homes with existing ductwork and performs well in moderate climates, providing heating and cooling in a single system. Our team can help you choose options that suit your home’s layout and energy-saving goals.
Signs of low refrigerant (Freon) include weak airflow, lack of cooling, ice buildup on the indoor or outdoor units, and higher-than-normal energy bills. If you notice any of these, call a professional. Adding refrigerant without fixing the leak can cause long-term damage to your system.
It’s rare, but possible, especially if your furnace isn’t well-maintained. Blocked vents, dirty burners, or gas leaks can pose serious fire or explosion risks. Routine inspections, cleanings, and proper installation are crucial for maintaining the safety and reliability of your furnace. If you ever smell gas or suspect a problem, turn off the system and call for emergency service.
A vinegar-like smell indicates mold or mildew growth in the system, typically caused by clogged condensate lines or dirty filters. A gas smell, however, may indicate a leak or improper combustion in natural gas systems. Both issues require immediate attention from an HVAC technician to ensure your home remains safe and your air remains clean.
