Air Conditioning FAQs
When should I consider replacing my air conditioning unit?
Determining the optimal time to install a new air conditioning unit involves considering several key factors. Typically, air conditioners have a lifespan of 15 to 20 years; as they age, their efficiency declines, leading to increased energy bills. Signs that your system may need replacement include frequent breakdowns, uneven cooling, or escalating repair costs. Additionally, advancements in HVAC technology have led to more energy-efficient models, which can result in significant long-term savings. Therefore, if your current unit is over 15 years old and exhibiting these issues, it may be time to consider installing a new air conditioning system.
Why should I look for an HVAC company with free estimates?
Seeking an HVAC company that offers free estimates is a strategic approach to managing your heating and cooling needs.

Moreover, free estimates provide insight into a company’s professionalism and transparency, as reputable firms like Carol Flynn Heating & Cooling, with over 65 years of experience, offer detailed assessments to build trust with their clients.
