Frequently Asked Questions

Why is my air conditioner leaking water or refrigerant?

The most common cause of water leaking from your air conditioning unit into your home is a clogged condensate drain line. Over time, dirt, dust, or even mold may build up in the line, creating a blockage. A broken condensate pump, dirty air filters that obstruct airflow to the evaporator coil, a damaged drain pan, or low refrigerant could also result in a water or refrigerant leak.

Are ductless mini splits good for heating my home?

Mini-splits that are properly placed, installed, and maintained can efficiently heat a home. Although they’re mini, they have various powers and capabilities and can pack a punch. Designed to deliver maximum output with little effort, mini splits can save you money on your energy bill while successfully heating your entire home. Placing the unit centrally is ideal so that heat can circulate evenly throughout your home, providing maximum comfort.

What should I do when my evaporator coil freezes?

If your evaporator coil is frozen, your first step is to turn off your air conditioning unit at the circuit breaker and allow time for the coil to thaw. Next, inspect your system for proper airflow. Make sure air filters are clean and clear, and that the evaporator coils are clean and unobstructed. If your coils are damaged, this could be the cause of the freezing, and you should have them repaired by a professional. Last, check your refrigerant levels to ensure they are not low, as this may lead to frozen evaporator coils.

Can my heat pump system produce carbon monoxide in my home?

All heat pumps run on electricity and present zero risk of carbon monoxide poisoning or gas explosions. Heat pumps are the safest and most efficient way to heat a home.

Can my water heater leak gas?

If you have a water heater that runs on gas, there is always a small chance that it could develop a gas leak. Although rare, gas leaks are dangerous and should be addressed immediately by a professional. If you notice gas leaking in or around your water heater, call for help ASAP.

Why is my thermostat’s display not working?

If your thermostat display is not working, check first to ensure the batteries don’t need to be replaced, and that your breaker isn’t tripped. If neither is the culprit, check the safety switch (installed in the drain pan) of your air conditioning system. If there is a problem with your system, the switch will automatically turn it off to prevent damages. A broken thermostat display could also indicate the need for a new thermostat if your unit is old and at the end of its lifespan.
