There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

• Ice forming on the evaporator coil

• Water leaks near the AC unit

• Frequent hissing sounds

• Increased electric bills

• Unit takes longer than usual to cool

• Unit is blowing hot air

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Here’s how AC professionals will clean your AC coils:

1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

2. Remove the faceplate.

3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

5. Use the vacuum hose to suck up any extra debris.

6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

7. Let the solution sit for at least 15 minutes.

8. Gently wipe away loosened grime and debris with a microfiber cloth.

9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.
