"Pacific Coast Home Services charged me $450.00 on May 10th to have my Air Conditioner repaired. On July 1st when the heat wave hit San Jose my air conditioner did not work. Pacific Coast did not stand by their GUARANTEE and I had to call another company to do the repairs. Thankfully, they were an honest company and made the repairs. Pacific Coast Home Services consisted of their salesman wanting to sell me a maintenance agreement for $900 ... I should have realized at that point he was not interested in fixing my problem and asked him to leave my house !!! He did remove a few leaves from the air conditioner and clipped a few nips off a bush nearby ... there was no repair done for his billing me $450.00. I am 92 years old and feel this was ELDER ABUSE !!! DO NOT CALL THIS COMPANY!!!"

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.
