Three Indicators an AC Unit Is on Its Last Legs
The weather is finally growing warm enough to begin considering turning on the air conditioning unit, or maybe it has been on for a week or two. Whatever the case may be, a working AC will be necessary for home comfort from here through the rest of the spring and summer. During this early spring season, it’s smart for a homeowner to keep their eyes and ears open for problems with the system to prevent a catastrophic failure and the need for AC installation in the hot summer months.
This article covers three major signs that indicate the need to repair or replace the air conditioner.
Unusual Noises and Worse Smells
- Banging Sounds: If the AC is banging there could be a problem with the compressor or something could be wrong with the cooling coils that are causing expansion and contraction of the surrounding metal.
- Whining Sounds: High-pitched sounds like squealing and whining may indicate a need for new parts.
- Musty or Damp Smells: If the air coming from the vents smells a bit off, swampy or musty, this is a sign that moisture may be collecting where it is not supposed to. This can be a problem resulting from several different parts.
- Burning Smell: A burning smell is never good and should be looked into immediately. This can indicate a problem with the blower or even a wiring problem.
Jump in Energy Expenses
When the first bill comes after switching on the AC, there is always a bit of sticker shock, especially if someone warms their home with natural gas. Air conditioning units do use quite a bit of energy. Still, if the bill is abnormally high, this is likely to indicate that the AC is growing less efficient and having to consume more energy to do the job it did before. It can be as simple as installing a clean filter, but age eventually trumps even the best maintenance record. A new energy-efficient AC may be just what the home needs.
Extra Indicators
A few more symptoms may crop up to show the homeowner that they need to install new AC. Contact an HVAC professional to replace the air conditioning or at the very least get a consultation about what is happening.
- Moisture: water tends to accumulate when there is a coolant leak or a blockage in the draining system.
- Inconsistent airflow: Poor air circulation means the fan and system of ducts are not working as they should.
- Warm air: If there is no cold air coming from the AC, there is an issue.
- Age: If a unit is 10 years old or older, the unit likely needs to be replaced.
