What should I set my thermostat at for each season?

You can easily save energy in the winter by setting the thermostat to a comfortable temperature when you’re at home and awake, and lowering it to a cooler, but acceptable, temperature when you’re asleep or away. • In the summer, you can follow the same plan with central air conditioning by keeping your house warmer than normal when you are away, and lowering the thermostat setting to a more comfortable temperature only when you are at home. • If you have a programmable thermostat, you can set it to automatically make these adjustments at different times during the day to match your typical behavior and maximize your savings with a minimum amount of effort.

What are SEER ratings?

When an HVAC unit works efficiently, it will consume less energy as it makes your home feel comfortable. A factor that helps you determine an air conditioner’s efficiency is its Seasonal Energy Efficiency Ratio (SEER) rating. An A/C’s SEER rating relates how much energy and money the unit will use during operation over the course of a year. Understanding what this rating means for you before an A/C installation will help you make an informed decision about the cooling unit that best meets your needs.

Customer Reviews

Our A/C went out on the hottest day of the year (thus far) so I called ARCO. They were able to send someone out the same day! Steve was able to diagnose the problem and fix it very very quickly and efficiently!

Jodi S.

Our experience with Arco was amazing. Robin in the office was great. She helped to get everything lined up and scheduled leaving no questions unanswered. Kris and Scott who came and did the installing were AMAZING.

Ellie K.

Great people and products, easy to do business. I replaced a window in my mobile home, and got good advice for roof and ceilings. Will be back.
