Q: What temperature should your air conditioner be in summer?

A: Set your air conditioner to around 75-78°F (24-26°C) in summer to balance comfort and energy savings. Adjust slightly higher when away to conserve energy. Finding the ideal temperature ensures a calm haven while optimizing efficiency.


Q: How much does an air conditioner cost to run?

A: Air conditioner running costs depend on unit size, energy efficiency, local electricity rates, and usage habits. Efficient models and strategic usage can help manage expenses, while larger units and continuous operation may lead to higher energy bills.


Q: How long does it take to install an air conditioner?

A: Air conditioner installation duration varies based on unit type, complexity, and location. Simple window units may take a few hours, while central systems could take a day or more. Professional installation ensures proper setup and efficient cooling for your comfort. Contact Poston Brothers for reliable air conditioning installation services in Union, KY and surrounding areas.


Q: Should you replace a 20-year-old HVAC?

A: Replacing a 20-year-old HVAC system is often recommended. Older units are less energy-efficient and prone to frequent repairs, increasing costs. Upgrading to a newer model improves comfort, reduces energy consumption, and offers better technology. Seek guidance from experts such as Poston Brothers to evaluate your unique circumstances and make well-informed choices regarding air conditioning replacement in Union, KY.


Q: What is the life expectancy of an AC unit?

A: The life expectancy of an AC unit typically ranges from 10 to 15 years. Regular maintenance, usage patterns, and quality of installation impact its lifespan. As units age, efficiency declines, and repair costs may rise. Considering replacement around the 15-year mark can lead to better long-term efficiency and comfort.


Q: Is it worth it to fix an old air conditioner?

A: Whether to repair an old air conditioner depends on the repair cost, unit age, and future efficiency. If repair costs are substantial and the unit is near its lifespan, investing in a new, energy-efficient model could offer better long-term value, comfort, and savings.
