Air Conditioning FAQs

There’s a lot to learn about air conditioning systems, from product selection to maintenance and troubleshooting tips. We have all the answers to questions about air conditioners, and these are some of the most frequent inquiries we get about AC systems.

1. What size AC do I need? There are two main factors to consider: your home’s square footage and its level of insulation. The average home in Texas is about 2,500 square feet, with urban areas featuring smaller square footage. A 4- to 5-ton AC is typically adequate for cooling 2,500 square feet, but a professional load calculation is the only way to determine the right size for your home.
2. Does my house need a central, ductless, or heat pump AC? Many Texas homes utilize a central air conditioner due to the hot climate and central air’s cooling capacity. However, homeowners who are interested in zoned cooling or energy efficiency may choose a ductless mini-split system or heat pump AC. We can help you choose the right option based on budget, energy needs, and existing ductwork.
3. What is the lifespan of an air conditioner? An AC system can last between 10 and 15 years as long as it receives proper maintenance. Visit our AC maintenance page for tips on making sure your AC gets the maintenance it needs to maximize its lifespan.
4. Why does my air conditioner keep turning on and off? This is a common issue called short-cycling. It might be caused by an oversized unit, clogged filters, or problems with your thermostat. Our AC repair services can provide the required solution.
5. Why is my AC on but not cooling? Your unit may be suffering from low refrigerant, dirty coils, or issues with the compressor malfunctioning. Schedule AC repair to restore your system’s cooling capability.
6. Why is my AC leaking water? Water leaks in your AC often indicate clogs in the drain line or insufficient refrigerant. Find out more on our AC repair page.
7. How often do I need AC maintenance? To keep your air conditioner running at peak efficiency and achieve its maximum lifespan, we recommend servicing your AC once before summer and again before winter.
8. How do I know if my air conditioner is efficient or not? Air conditioners have a SEER rating, which stands for Seasonal Energy Efficiency Ratio. The less energy used to produce the right amount of cooling, the higher the unit’s SEER rating. You can also look at whether your unit is cooling consistently and whether your energy bills are manageable. If your system is struggling, upgrading to a modern, energy-efficient unit can make a big difference in your comfort and cooling bills.
9. When do I need to replace my air conditioner? If your unit is approaching the 15-year mark, needs more frequent repairs, or isn’t cooling as efficiently as it should, it may be time to replace it. Our AC replacement page has the details you need to make an informed decision.
10. What is the most common type of AC unit in Texas? Central air conditioning is the most common in Texas homes, thanks to the ability to efficiently cool larger spaces in hotter climates. However, other types of AC are beginning to gain traction as technology continues to improve.
