Why choose SumZero for air conditioning repairs?
We're local, responsive, and focused on customer satisfaction. With transparent pricing and expert technicians, you're in good hands with SumZero.
Will I get a quote before you do the repair?
Absolutely. We explain the issue and provide a straightforward quote before any repair work starts—no pressure, no surprises.
How long does a typical A/C repair take?
Most A/C repairs take 30 to 90 minutes depending on the issue. We'll give you a clear estimate before we begin work.
Do you work with all A/C brands and models?
Yes, we repair all major air conditioning brands—whether it’s central A/C, mini-split, or packaged systems.
Is it better to repair or replace my A/C system?
If your system is under 10 years old and the repair is minor, fixing it makes sense. We’ll give honest advice based on your situation and long-term comfort.
What if my A/C is blowing warm air?
This could be due to low refrigerant, a faulty compressor, or airflow problems. Our techs will quickly identify the cause and get it fixed.
Can you repair my A/C unit on the first visit?
In many cases, yes. Our service vehicles are stocked with common parts, so we can often complete the repair right away.
How much does it cost to diagnose an A/C issue?
We offer a flat-rate $99 diagnostic visit, which includes a full system inspection and a clear explanation of any needed repairs.
Do you offer same-day A/C repair services?
Yes! We do our best to provide same-day appointments depending on availability and urgency, especially during hot weather.
What are the most common signs that my A/C needs repair?
Warm air, unusual noises, weak airflow, frequent cycling, or rising energy bills are clear signs your air conditioner might need attention.
