If you want to beat the heat, you need to be sure your AC unit is working properly. Luckily, the HVAC maintenance professionals at 3-D Sheetmetal in Honolulu, HI, are able to recognize when an AC unit is in need of repair. Proper HVAC maintenance requires you to stay on top of issues. Don't wait until it's already scorching outside to call for AC repair. 

Keep alert and contact 3-D Sheetmetal if you notice any of these four signs:

• Warmer Air: You shouldn't have to keep your AC on full blast just to keep your home comfortable. If the air isn't as cold as it used to be, it's in need of a repair to improve energy efficiency. 
• Weak Air Flow: If some rooms in your house are cooler than others or you notice the air flow is weak overall, it's probably because your compressor is failing.
• Odd Sounds: Screeching or grinding sounds coming from your unit mean there are some internal issues. Don't ignore them even if everything else seems in order. You could end up with a complete breakdown.
• Bad Smells: Foul odors coming from your unit could mean there's mold growing on the inside or your wire insulation has burned up.
