Signs Your Air Conditioning Needs Updated

An air conditioner that struggles to keep up during hot weather may be telling you it’s time for an upgrade. Older systems often lose efficiency, driving up your energy bills and leaving you with uneven comfort from room to room. Strange noises, weak airflow, or frequent repairs are all warning signs that your unit is nearing the end of its lifespan. Ignoring these red flags can lead to costly breakdowns when you need cooling the most. Professional AC installation ensures you’ll have a reliable, energy-efficient system that keeps your home comfortable all summer.

  • Rising energy bills despite regular use
  • Frequent breakdowns or costly repairs
  • Weak or inconsistent airflow from vents
  • Strange noises or unpleasant odors during operation
  • AC unit is more than 10–15 years old

Dalton came out for our annual furnace maintenance and did amazing!

Called 3 companies early in the morning. Stay Cool was able for me to take pics of the area while other companies wanted to come out 3+ days later to look while we had no hot water. Stay Cool was able to come out the same day which was a huge plus for us since we had not had hot water for 2 days already. Their price was also $350 and $700 cheaper than 2 other companies I have had in the past. Travis and Carter showed up on time and walked me through the tearing out and install of the new heater. They were courteous of their wet shoes with slips if they had to go to their truck outside when tearing out the old water heater. Carter, with our older heavy door headed to the garage it doesn't take much to close it. Please be easier in the future. There was an issue with the old water heater being taken up the steps with a dolly that scrapped all the way up the steps in pic 2. I called the main office, they apologized, and they sent Travis back out the next day to repaint. Ill still keep them in mind for future projects. thank you.

I had Stay Cool come out for my furnace that quit working while I had just had surgery. Cindy was able to get someone out right away, I had signed up for the membership club that saved me on my repairs, and felt very confident in the technician. He made me feel at ease and comfortable in my decision . Very friendly company that does the job right the first time!

Nathan and Trey came out to do an installation on the exterior, but stuck around to help test my system and give guidance on improving house heating. We found an issue with a fan not being connected to an exhaust pipe and they went out, got materials, and came back and fixed it that day!
