Noticing that an AC unit isn't cooling like it used to, most people call a technician right away without checking the filter - though a large share of problems come down to a simply clogged filter, something fixable at home.
What signs point to needing repair
Reduced cooling power, unusual noise during operation, water dripping, or the unit not turning on at all are the most common signals. A strange smell usually points to a dirty indoor unit.
How AC repair pricing is formed
AC repair pricing depends on the type of issue (basic cleaning, refrigerant refill, compressor failure) and the unit's model. If a refrigerant leak is found, the leak point needs to be located first and only then refilled - otherwise the problem returns quickly.
What a refrigerant leak leads to
A drop in refrigerant level reduces cooling power and puts extra strain on the compressor, which over time can cause it to fail completely. Catching a leak early prevents an expensive repair later.
What regular maintenance should include
Regularly cleaning filters, keeping the outdoor unit free of dirt, and a general pre-season check extend an AC unit's life. Many breakdowns happen simply because this maintenance was skipped.
DIY or call a technician
Cleaning a filter is an easy home job, but refrigerant refills, compressor repair, and electrical faults require specialized equipment and certification - attempting these yourself can be dangerous and may void a warranty.
What to look for when choosing a technician
Experience with the specific brand, whether the refrigerant used is genuine, and post-repair warranty terms are the main things to check.
FAQ
How often should an AC unit be serviced?
One general checkup a year is recommended, usually before the summer season starts.
How long does a single refrigerant refill last?
Without a leak, a single refill can last for years; with a leak, the problem will keep recurring until it's fixed.
Is it better to repair an old unit or buy a new one?
If the repair cost exceeds about half the price of a new unit, buying new may be the more sensible choice.
