Common Questions
What should I do if my air conditioner isn't cooling, and I suspect a refrigerant leak?
If you notice reduced cooling, ice on the coils, or hear a hissing sound, a refrigerant leak is a common possibility here in Greenwood. We handle this by first performing a thorough inspection to locate the leak using specialized detection equipment. Once found, we repair the leak, evacuate the system, and recharge it with the correct amount of refrigerant to manufacturer specifications. Properly addressing leaks is crucial for your system's efficiency and longevity, especially with our local humidity.
How do I know if I need an HVAC repair or a full system replacement?
This is a common question for homeowners. During a service call, we'll assess your system's age, repair history, efficiency, and overall condition. If your system is over 10-15 years old, requires frequent repairs, or has significantly rising energy bills, a replacement may be the most cost-effective long-term solution. We provide honest, transparent recommendations to help you make the best decision for your home and budget, with no pressure.
What does your two-year customer satisfaction guarantee cover?
Our guarantee covers all parts and labor for any installation or repair work we perform for a full two years. It's our promise that the job is done right. If you're not completely satisfied with our work for any reason within that period, we'll make it right at no additional cost. This guarantee reflects our commitment to the trust Greenwood residents place in us.
