Some common warning signs include warm air blowing instead of cold, weak airflow, unusual noises (buzzing, grinding, rattling), frequent cycling on and off, water leaks or excess moisture near the unit, spikes in your electric bill, or odd/unpleasant odors.

This may be caused by low refrigerant levels (possibly due to leaks), dirty or blocked condenser/evaporator coils, a faulty compressor, or thermostat issues. Poor airflow (dirty filters or blocked vents) can also reduce cooling performance.

Turn off the system and inspect the condensate drain for clogs; check the drain pan for damage; confirm that the condensate line is clear. If the leak persists, it’s best to call a professional technician to find and fix the source of the problem.

Ice buildup may result from restricted airflow (due to dirty filters, blocked ducts, or closed vents), low refrigerant, or a malfunctioning blower motor. Continuing to run a frozen AC can damage components, so it’s important to address this quickly.

There are a few minor tasks homeowners can safely do: change the air filter, keep the outdoor unit clear of debris, routinely check thermostat settings. But more complex repairs—especially involving electrical components, refrigerant, compressors, or internal coils—should be handled by licensed HVAC professionals to ensure safety, proper code compliance, and warranty protection.

That depends on several factors: the age of your unit (many units last around 10-15 years), frequency and cost of repairs, energy efficiency of the current unit vs replacement, and your long-term plans (how many more years you intend to stay in the home). If repair costs are high and the system is old or inefficient, replacement may be more cost-effective.

First, check basics: thermostat settings, power supply (breaker panel), ensure outdoor unit is unobstructed, check filter. If everything seems normal but AC still doesn’t work, contact an HVAC technician. We also offer emergency repair services to respond quickly when heat becomes a safety issue.
