You wouldn’t run your car without regular maintenance, right? The same goes for your PTAC unit. If you’re running one in a hotel room or apartment, efficiency isn’t just about comfort—it’s about cutting costs and preventing breakdowns. So let’s get into it.
1. Keep Filters Clean and Clear
The #1 enemy of efficiency? Dirty filters. Clogged air filters make your PTAC unit work harder, meaning more energy use and higher bills. Make it a routine to clean or replace filters every 30–60 days.
2. Seal Drafts and Insulate Well
You can have the best PTAC on the market, like the Amana Distinctions 14,700 BTU PTAC Unit with 3.5kW Electric Heat, but if your room’s leaking air through windows or doors, you’re throwing money away. Weatherstrip and insulate to keep that cool (or warm) air where it belongs.
3. Use a Programmable Thermostat or Energy Management System
Especially in hotels, energy management systems (EMS) that adjust PTAC settings when rooms are unoccupied can lead to big savings. For apartments, consider installing a programmable thermostat to reduce unnecessary usage.

4. Regular Maintenance Checks
Twice a year, inspect your PTAC unit. Look for signs of corrosion, listen for unusual noises, and check refrigerant levels. Preventative maintenance is cheaper than emergency repairs any day.

5. Choose Energy-Efficient Models When Replacing
If your unit’s pushing 10–15 years, replacement might be smarter than repairs. Newer models, especially those using R-32 refrigerant, are designed to be more energy efficient and environmentally friendly.
Final Tips From Mike
Keep your PTAC running efficiently and you’ll notice the difference—in your comfort and your wallet. These units are built to perform, but they need a little help from you. Regular checkups, good insulation, and smart usage go a long way.
Got an aging unit? The Amana Distinctions 14,700 BTU PTAC is a solid replacement that blends performance with value.
Until next time—keep it cool,
