We are an American standard customer care dealer which means we go above & beyond to ensure a great experience with Clark heating. We have many times been recognized as "dealer of the year" for providing unmatched service. We've accomplished this by maintaining customer satisfaction rating of over 98%. Contact us today, we'd love to make you a satisfied customer too.

"Great to work with. They were efficient and knowledgeable. They took care of the rebate for our heat pump. Only thing lacking was responsiveness to email/phone communication after the install was done. Heat pump system is working great."

"Technician Jim was not impressive. Was not confident when answering the questions I asked. Very contradicting.. Tried to sell product for items that were not even in need of repair. Spoke negatively about the company and made excuses as to why he could not perform his job due to lack of information from dispatch or technician manager. Said he would follow up, I never heard from him. Blessing to me, I decided to go with another HVAC company. I typically would not put names out there, but please be careful if you get this gentleman as a technician."

Central a/c service or repairs FAQs

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.
