⚡ Old AC causing high electric bills?
Why Is My Old AC Using So Much Electricity?
In Florida, air conditioning can be half of your summer electric bill. An outdated, inefficient air conditioner can cost you hundreds of dollars a year more than a modern system.

Why old air conditioners waste energy
- Lower original efficiency: many systems installed before 2015 are 10–13 SEER.
- Wear: dirty coils, worn compressors and weak fan motors lose 1–2% efficiency per year.
- Refrigerant leaks make the system run longer to reach the same temperature.
- Single-stage compressors run at full power all the time, even on mild days.
SEER vs SEER2: what changed in 2023
Since January 2023, efficiency is measured with SEER2, a test that better reflects real duct pressure. The federal minimum for new systems in the Southeast, including Florida, is 14.3 SEER2 (about 15 SEER under the old scale). High-efficiency options reach 16–20 SEER2.
How much can a high-efficiency AC replacement save?
Going from an old 10 SEER system to a 15+ SEER2 system can cut cooling energy use by up to 40%. For a typical Florida home that spends $200+ a month on summer electricity, that can mean significant yearly savings that help offset monthly financing payments. Actual savings depend on your home, usage and utility rates.
Benefits of high efficiency AC replacement
- Lower monthly electric bills
- Better humidity control and comfort
- Quieter operation
- New manufacturer warranty of up to 10 years

“Wow! They did amazing from start to finish. We needed a new outdoor unit and they ended up replacing both the indoor and outdoor unit for a great price. Everyone else quoted us thousands more than them and they delivered excellent service and quality products.”

“I had them replace my HVAC system and they couldn't have come at a better time. The AC unit quit working during one of the hottest periods in July. They were there when they said they would and replaced the system in a timely fashion.”

“Was struggling with getting a AC at a good price and Miguel was very direct honest and bilingual, and I felt like I got a good deal and I would hire him again. I am going to recommend him to all my friends and family. Couldn't be happier.”
