“We had an erratic furnace lighting situation a couple weeks ago. Both David and Eric came out to diagnose and fix the problem which turned out to be a clogged moisture drain trap. They came on time, mindful of making sure they kept things clean, clearly explained the situation, and were both courteous and pleasant to interact with. Would not hesitate to recommend.”

FAQs
Find answers to common questions about our HVAC services and pricing.
Why is my AC running but not cooling?
There are several common reasons an AC system runs but fails to cool properly. The most frequent causes include low refrigerant levels due to a leak, a dirty or clogged air filter restricting airflow, frozen evaporator coils, a faulty thermostat, or failing capacitors and electrical components. In some cases the outdoor condenser unit may be blocked or the compressor may be struggling. Because many of these issues share the same symptoms, a professional diagnostic inspection is the most reliable way to identify the exact cause and avoid misdiagnosis — Art of Comfort technicians use a full system evaluation to find the root problem, not just the symptom.
Should I repair or replace my air conditioner?
The decision to repair or replace depends on the age of your system, the cost of the repair, and how efficiently the unit has been running. A general rule of thumb is the '5,000 rule' — multiply the age of the unit by the estimated repair cost, and if the number exceeds $5,000 it is usually more cost-effective to replace. If your system is over 10 to 12 years old, requires frequent repairs, struggles to maintain consistent temperatures, or is driving up energy bills, a replacement will likely deliver better long-term value. Art of Comfort provides honest, no-pressure assessments and offers a free second opinion on any major repair or replacement estimate you have already received — so you can make the decision with confidence.
How quickly can AC repairs be completed?
Most AC repairs by Art of Comfort are completed the same day, including common issues like refrigerant recharges, capacitor replacements, electrical fault repairs, and drainage fixes. More complex repairs involving compressor replacement or parts that require ordering may take an additional day or two. Art of Comfort is known across the Tri-Valley for fast response times — customers regularly highlight the team's ability to diagnose and resolve AC issues quickly, even during peak summer months when demand is highest. Call (925) 291-0871 to check same-day availability.
What does an AC diagnostic inspection include?
Our technicians inspect the full system, including the thermostat, electrical components, refrigerant levels, and internal components. The goal is to identify the root cause of the cooling problem before recommending a repair, rather than treating only the symptom.
Will I know the AC repair price before work begins?
Yes. Art of Comfort provides transparent, up-front pricing on AC repairs in Pleasanton and the Tri-Valley. After diagnosing the issue, our technicians explain the repair recommendation so you can decide without pressure. If the system is beyond repair, we can help evaluate replacement options.
