What Our Clients Say

I have used Blackburn & Davis several times, quite satisfactorily. On-time, friendly, and reasonable. The most recent was to check for leaks and for ball valves in preparation for new LG&E gas service. They replaced two older gate valves, did a leak-down check, and submitted the load slip to LG&E which included future expansion of service if I add a natural gas-fired generator. The utility installed a much larger meter and a tee for the added service as I wanted.

Signs Your Furnace Needs A Repair

Knowing when to call for a furnace repair can have a great impact on the longevity of your unit. If you are experiencing any of the following signs, please give our HVAC repair team a call.

  • Abnormal Smells: A slight scent as soon as the unit turns on is normal, and usually dissipates in a few moments. However, if the scent is strong, or grows more intense – it may be a sign of a larger problem.
  • Trouble Starting The Unit: This is likely caused by disconnected or damaged wiring, which can be a simple furnace repair. If you have to try multiple times to start or restart your furnace throughout the day, you likely need a furnace repair.
  • Discolored Pilot Light: A healthy pilot light usually appears blue, if it is any other color, that’s a problem. If your pilot light is yellow, that indicates a ventilation problem and indicates that carbon monoxide isn’t dissipating as it should.
  • Low Levels of Heat: It’s clear your unit has a problem when it’s not doing its job. If the unit is turning on and seems to be working while you’re still freezing, it’s likely a furnace repair involving ductwork or a thermostat issue.
  • Unusual Noises: Every furnace makes some noise, but if they are loud or distracting, that is likely cause for furnace repair. Squealing and whistling are from belt and fan issues while banging or groaning may be loose internal components
  • Poor Air Quality: If you notice your home is particularly dusty or your family is experiencing more coughs and sputtering than normal, it might be time for a furnace repair. It could be something as simple as a filter while in some cases may require ductwork cleaning.
  • Carbon-Monoxide Detector Goes Off: The Carbon-Monoxide detector is designed to alert you to the presence of natural gas and will automatically turn the furnace off if gas is detected. If this occurs, don’t hesitate to call our office.
  • High Utility Bills: If you notice your utility bills are higher than normal, this is often an indicator that something has gone wrong. This often occurs when your furnace is working harder than normal or there is a leak in the ductwork. A trained HVAC technician can find the problem, repair it, and advise on next steps.
  • Pooling Water: A water leak is usually not a significant problem, but still should be addressed by a repair technician to ensure it’s nothing to be concerned about. This is especially important if a leak is coming from the unit itself.
  • You Smell Gas: A gas leak is a cause for immediate concern. Shut down the furnace, leave the house, and call Blackburn and Davis, Inc in Louisville, KY ASAP.
  • Weak Air Blowing: If the air is barely coming out of the vents, it’s likely going to require a furnace repair with the fan, belts, or motors.
  • Frequent/Constant Cycling: You can hear your furnace kick on throughout the day, but if it’s cycling on and off over and over, that is a problem. Often, this is caused by a clogged filter or improper air circulation. Generally, a furnace repair technician can diagnose this problem for you.

Benefits of A New Furnace Installation

If you keep having to call for a furnace repair and/or your furnace is near the 15 year old mark, it is a good idea to give us a call. It’s worth it to consider if replacing your current heater is better than ongoing furnace repair which can be unsafe as well as costly.
