Air Conditioning Maintenance FAQs
Some of the frequently asked questions we receive about AC maintenance include:
Can I Do My Own Air Conditioner Maintenance?
Yes. Here are some steps you can take between fall (heating) and spring (cooling) professional maintenance visits:
- Clean dirt and clear debris from around your outside condenser unit.
- Don’t let piles of stuff accumulate near your indoor AC/HVAC unit. Keep the area and the unit itself clean.
- Consider installing ceiling fans to improve air circulation throughout rooms if you don’t have them.
- Replace air filters as needed or according to the manufacturer’s instructions.
- Vacuum and clean air vents every 30 to 60 days.
My Cooling System Works Fine. “If It Ain’t Broke, Don’t Fix It,” Right? Why Should I Pay For AC Or HVAC Maintenance?
Maintenance saves money. Without it, you’ll be lucky to get 10 years of service out of your system. With AC maintenance, it can serve you five more years or even longer. Plus, emergencies never happen at the “right” time. When it’s crazy hot and humid, that’s when your air conditioner will quit. We’re available 24/7, but emergency calls cost more. Depending on where you live in the USA, you may pay as much as $50-$150/hour for emergency AC service. A refrigerant recharge can cost $100-$350. Buying a new air conditioning system can cost between $2,426-$8,900, including the removal of your old unit and installation. If you haven’t had any maintenance, your ductwork may also need cleaning or work for an extra cost.
