When the summer sun is blazing and your A/C is working overtime, the last thing you want is a surprise breakdown—or a shocking energy bill. At New Knoxville Supply, we believe your HVAC system should keep you cool and cost-effective all summer long.
Top 5 Tips
Here are our top tips to help your air conditioning system run smoothly, stay energy-efficient, and avoid those sweaty emergencies:

1. Change (or Clean) Your Air Filter
It’s easy to forget, but this simple step is one of the most important. A clogged or dirty filter makes your system work harder, which means:
- Higher energy bills 💸
- Less cool air ❌
- More wear and tear ⚙️
Pro Tip: Check your filter every 30 days during summer and replace it if it looks dirty. You’ll breathe easier—literally.
2. Schedule a Professional Tune-Up
Think of this as a wellness check for your HVAC system. Our trained techs will:
- Clean coils and drain lines
- Check refrigerant levels
- Inspect electrical connections
- Test airflow and efficiency
Even if your A/C seems fine, a tune-up can catch small issues before they turn into major, sweaty problems.
3. Use a Programmable Thermostat
Don’t cool an empty house! A programmable thermostat helps you:
- Set temps higher when you’re away
- Automatically cool things down before you return
- Save energy without lifting a finger
Need help upgrading or setting one up? Our team can walk you through it.
4. Keep Vents and Outdoor Units Clear
Blocked vents or a buried outdoor condenser unit can reduce airflow and efficiency. Take a walk around your home:
- Keep furniture and rugs away from vents
- Clear grass, leaves, and debris from around your outdoor unit
- Make sure pets (or kids!) haven’t built a fort near it.
5. Watch for Warning Signs
If you hear unusual noises, see ice forming on your A/C, or notice your home isn’t cooling like it used to—don’t wait! A small issue can quickly become a major repair if ignored.
