In 2020, the global market for Heating, Ventilation, and Cooling (HVAC) systems stood at $136.15 billion. In the next 6 years, this number is expected to skyrocket to reach $202.14 billion.
The ability that an HVAC system has to pull in polluted air and purify it contributes to the growing demand for heating and cooling systems. Even if you live in a place with clean air, you can’t beat the comfort of a cozy, climate-controlled indoor space.
But, what do you do when HVAC emergency strikes? This blog will walk you through common ways that HVAC systems fail and who to call when they do. Grab a blanket or turn on a fan and read on!
Heat Pump Problems
Heat pumps are growing in popularity over conventional heaters because they cool and heat more efficiently. An air-source heat pump can provide 1.5 to 3 times the heat energy to a home than it consumes in electrical energy.
Common heat pump issues include:
- Pump running constantly
- Pump not running at all
- Frozen outdoor unit
- Air handler not working
- Pump not heating or cooling
- Pump short cycling or switching modes
If you’ve checked your thermostat settings and replaced a dirty air filter and these things are still happening, call a heat pump technician to help you out.
Motor Madness
The blower motor turns on the fan and sends treated air through the ducts and into each room in your home. If it’s not working, your home will not get warm and your heater runs the risk of overheating.
A blower motor may stop working if:
- The blower motor belt broke and does not spin the fan
- The motor needs lubrication
- The internal motor assembly came loose or broke apart
While your HVAC is running, keep an ear out for noises that sound out of the ordinary. Screeching, flapping, or banging indicate the need to call an HVAC technician to check out the motor.
Clogged Condensate Chaos
The condensate drain transports condensation from the evaporator coils and out of your home. The drain line is an enclosed, wet space. It is an ideal location for mildew, mold, and sludge to accumulate.
You may have a clogged line if:
- Your AC unit isn’t cooling your home
- The AC is dripping water
- The AC won’t turn on
- You suddenly have higher energy bills
You can clear out the condensate line by turning off the AC, removing any noticeable debris, and flushing the line with one cup of distilled white vinegar. If problems persist after your treatment, call in an expert to help you out.
Electrical Emergency
A burning smell coming from your HVAC unit indicates a problem with the electrical components of your system. Electrical problems often arise as a result of:
- Loose wires
- Clogged furnace filter
- Dirty or incorrect fuse
- Failing motor
- Bad thermostat wiring
Like all other electrical concerns, for safety reasons, it’s best to leave these types of fixes to trained professionals.
Book HVAC Emergency Service
