Heating and Air Conditioning questions, answered by experts

Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

While it’s possible to only replace an evaporator coil to keep your AC running, this could cause issues down the line. An AC system relies on the harmony between its condenser and evaporator coils for efficient operation. Replacing only one coil, especially in older units, can cause compatibility issues, leading to inefficiency and potential system breakdown. 

As AC units near the end of their expected lifespan, investing in the cost for a new AC system is typically better than paying for individual component upgrades to avoid costly repairs and ensure optimal performance.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.
