"Our heater broke and my husband is medically fragile and It was 58 degrees INSIDE. I needed help ASAP. He's 88 and I'm 77 and calling people was frustrating until I checked top Angie reviews for my area. Even then, two out of three failed on ability to respond in less than 7-10 days. Another said we can come assess in three days and then schedule your repairs. 411 came within hours and had us heating up with a brand new, quieter, and quicker system the next day! Can't thank them enough. And the pricing was very fair based on checking with others in our neighborhood and relatives who have had to replace their systems."

An evaporator coil is a crucial component of your air conditioning system, responsible for cooling the air inside your home. It absorbs heat from the indoor air, allowing the system to blow cool air through your vents. Keeping your AC well-maintained helps it run efficiently and can save you money on energy bills.
AC condensers can present a variety of common problems, including dirt and debris accumulation, drain blockages, and water leaks. Leaking refrigerant, faulty electrical components, damaged coils, and burnt-out motors can indicate more complex repair needs.
Some of these issues can be easily fixed, while others may require a total unit replacement. For the most accurate assessment, contact an AC contractor in your area.
The AC coils typically last the lifetime of your system, ranging from 10 to 20 years, depending on factors such as maintenance, quality, and other variables. Have your AC condenser coils inspected and cleaned periodically to maximize their lifespan and optimize cooling performance. Ask your HVAC pro for recommendations on how to stay on top of all critical AC maintenance.
Home warranties cover AC coils when the policy explicitly protects key HVAC components. This means that if an AC coil fails under the scope of your warranty, repair or replacement expenses are covered. Your warranty documentation confirms whether coil repairs are included, and manufacturer warranties protect both the AC condenser and its coils. It is important to review your contract details to know your exact coverage.
Warning signs that your AC condenser is failing include noticeable fluid leaks and loud, unusual noises. These indicators confirm that the condenser is under stress and its performance is compromised. Decreased cooling efficiency, uneven indoor temperatures, and increased energy consumption further signal that the unit is deteriorating. Recognizing these signs ensures you engage a professional for a thorough evaluation and prompt repair.
