Hello, My Name is Johnathan Steele, Owner Operator of Show-Me Comfort Heating and Air Conditioning. I started my company with the intent to help and show transparency to my customers and to educate them to the best of my abilities on the system that keeps their Home Comfortable. Most Companies will come in to a house fix the issue then leave… That’s where we try and separate ourselves by finding the culprit, educating our customers on why it happened and how to prevent future problems. \n\nWe at Show-Me Comfort Heating and Air Conditioning take pride in our work, and if we wouldn’t do it in our house we wouldn’t do it to yours.

Heating and Air Conditioning questions, answered by experts

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.

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.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
