Air Conditioning and Heating Repair Tips from Tim Bob | Dallas and Plano Heating and Air Conditioning Repair Blog

Here's another guest blog from Tim Bob, the HVAC tech that I recommend to all of my clients.   

 AC and Heater repairs are best left for the professionals

 Without proper tools or training, repairs end up with disappointing reports.  Many repairs we are called out on are to correct improperly made repairs.

 Here is a summary of common repairs and stumbling blocks a home owner may encounter.

  • Replacing motors. The propellers or blades will be bent if a specialty propeller puller is not used.  The unbalanced prop or wheel will eventually ruin the bearings on the new motor.
  • All Furnaces.  Many failed parts are parts that monitor the safe operation of the heat producing parts.  The cause of the failed safety part must be identified. 
  • Gas furnaces.  Computer boards are now used on most new furnaces and the need of manufacture's information to properly diagnose their failure. Older furnaces, using a thermocouple are probably near the end of their lives.  A homeowner will not recognize a potential deadly crack in the heat exchanger or the fire danger of dirty burners.  These old furnaces do not have the safety circuits that newer furnaces now have to protect you.
  • Electric furnaces.  Heavy current conductors need to be recognized for loose connections. Many furnaces use as much power over 250 light bulbs!  Most of the time, there is no way to turn the power off near the unit.  Smoke could pour out of the unit before the home owner can get to the breaker panel.
  • Thermostat replacement- Many of my service calls are to correct problems caused by incorrect thermostat installations.  Usually the problem is the wrong thermostat application for the HVAC system.  Occasionally, other parts are then ruined.  A thermostat set for "electric heat" probably is the wrong setting for an electric furnace.  A technician knows why "gas heat" is the better option.
  • Heat pumps- everything is confusing about these. A thermostat replacement is even a challenge to the experienced technician.  With up to three stages of heat, time delay settings and software settings, a wrong set-up will result in inefficient energy savings.  Home depot sells single stage "heat pump" thermostats that simply are the wrong thermostat for most systems.
  • Working in the attic- It happens a lot. Falling or stepping through the ceiling.  Ruins all your day.


Parts sold to home owners are sold at retail, the service company buys at wholesale and then sells at retail, allowing our profit.  We are required to carry insurance and our license is subject to customer complaints.  We guarantee our parts and labor.  Labor rates may be high, but we have the tools, the manuals, and experience that allows us to work quickly.
