Max C. Smith Company is proud to provide our industry with leading heating and cooling services to the North Hills, Cranberry, Wexford, and North Pittsburgh region since 1868! Our team of highly trained HVAC experts can repair and service all makes and models of existing air conditioning systems. Plus, as a proud Lennox & Amana dealer, our heating and air conditioning experts can help to replace and install new and efficient heating and air conditioning systems, as well.

QUICK TIPS:

  1. Check your thermostat to make sure it is set in the correct mode and is calling for heating or cooling.

  2. Check your filter. Make sure it is not clogged or dirty. This can cause the equipment to fail, and will affect the efficiency of the system. 1” filters should be replaced once per month. 5” media filters should be replaced once or twice per year.

  3. Check to see if the circuit breaker is in the "On" position. This can save you a service call if the breaker happens to be tripped.

 

Air Conditioning Equipment Checklist:

  • Check to make sure that your thermostat is set in the "cool" position.

  • Make sure that the temperature setting on the thermostat is set lower than the indoor temperature showing on the thermostat.

  • Ensure that the blower motor in your furnace is running. (If the thermostat is in the "cool" position, the furnace blower should be running.)

  • Ensure that your outdoor air conditioning (condensing unit) is running:

  • Check the circuit breakers in the circuit breaker box (or electrical panel), most likely mounted to an outside wall in the back of the house. Are they in the "On" position?

  • Be sure that you have changed your filter in the furnace. An extremely blocked filter can cause your outdoor air conditioner unit to shut down due to lack of proper airflow.

Gas Furnace Equipment Checklist

  • Check to make sure that your thermostat is set in the "heat" position.

  • Make sure that the temperature setting on the thermostat is set above (or higher than) the indoor temperature showing on the thermostat.

  • This tells your heating system that it should provide heat!

  • Ensure that there is power to the furnace:

    • Try turning the fan to "ON" using the fan switch on the thermostat to test for power to furnace.

    • Check the circuit breakers at the electrical panel to make sure they are in the "On" position.

    • Check the SSU switch (it looks like a light switch on a gray box located at the furnace) to be sure it is in the "ON" position

  • Replace the furnace filter if needed.

If you smell gas, call the gas company from a neighbor's home!

No Heat - Furnace will not ignite

Older furnaces with pilot lights can experience outages due to failed thermocouples, dirty pilot burners, or failed gas valves. On some of the newer models, an ignition control or a hot surface igniter could be at fault. These are typically stocked items that we carry for your convenience. There are many other potential causes that our knowledgeable team is happy to diagnosis and repair.


Intermittent heat heats occasionally, does not keep the temperature regulated, or the furnace is blowing cold air. Circuit boards are found in most modern heating equipment. These boards will lock out in the event that a sensor picks up a system malfunction. It will attempt to run approximately 3 times, and then will switch to the lock out mode. This mode will run the fan continuously, and will blow cold air. Also, you may notice a sequence of flashing lights located in the sight glass of the furnace. If so, count and write down the sequence as this will help to guide the service technician to find the cause of the failure. It is best to call a service technician to troubleshoot the problem. However, if it is extremely cold, after you determine the sequence of flashing lights, you can reset the “lock out” by turning the power switch off then back on again. This will allow the furnace to attempt to re-light.

Noisy Furnace

The noise is noticeably different than its normal operating noise.  All machines will make some operating noise; however, if you hear an unusual sound such as metal rubbing together or grinding, it may mean the motor is failing. Whistle-type sounds could mean your system is having trouble breathing or there is a lack of air. Check your filter to make sure the registers are open. Air movement can create a whistle sound similar to a car window being cracked. If you are experiencing any loud banging, turn off the equipment and call Max C. Smith, your 24 hour furnace repair company.


Not Cooling

No cooling - central air conditioning (AC) is not blowing cold air. First. if you are still unsure of the problem, check if there is any ice near the top of the furnace. If so, switch the thermostat from cooling to the off position, then switch the fan from Auto to On. This will start the melting of the ice so a service technician can diagnosis the problem. If the outdoor unit is not running or the fan is not spinning, turn the system off. This most likely means that an electrical component has failed. This could be as simple as a capacitor or contractor, or it could be something more involved like a motor or compressor. Either way, it is recommended to shut off your system and call Max C. Smith for your AC repair services.

Maintenance

Most manufactures will recommend routine maintenance. This is to be done by a trained professional because every system requires different procedures. Routine maintenance prolongs system life, catches small problems before they turn into failures, and insures the equipment is running at peak efficiency. We recommend having maintenance done twice per year, once for heating and once for cooling. Get in touch with the Max C. Smith team today to get your heating and cooling problems fixed the right way!
