Delta heat is real heat. When the breeze quits in July, Antioch attics hit 140 degrees and marginal systems give up. Our East County route puts a tech in Antioch every working day, with the common failure parts already on the truck.
Our trucks roll out of Concord stocked with the parts that fail most: capacitors, contactors, fan motors, and control boards for every major brand. Most repairs finish in a single visit. We answer the phone 24/7, and a real person picks up, not a phone tree.
Before any work starts, you get the price. You approve it, then we fix it. That has been the deal since 1998.
What we fix every week
- No cold air at all
- Weak or warm airflow
- AC won't turn on
- Ice on the refrigerant lines
- Water pooling at the unit
- Grinding or buzzing sounds
- Short cycling (starts and stops)
- Cooling bills suddenly higher
What happens when you call
- Call or book online
A real person answers 24/7. You get a 2-hour arrival window, and we call when the tech is 30 minutes out.
- Flat-rate diagnosis
The $89 diagnostic covers a full system check. You get the findings in plain English with the exact repair price, up front.
- Fixed on the first visit
Our trucks carry the most common parts for every major brand, so most repairs finish the same day.
- Tested, backed, guaranteed
We run the full system before we leave. Parts and labor are covered for one year under the Summit Seal.

Questions homeowners actually ask
How much does AC repair cost?
Most repairs run $189 to $650 depending on the part. The diagnostic visit is a flat $89 and is applied to the repair price. You approve the total before any work starts.
Can you really come today?
Usually, yes. We staff for same-day service across our five-city area and answer the phone 24/7. Emergency calls get the next available tech.
Should I repair or replace my AC?
Our rule of thumb: if the repair costs more than a third of a new system and your unit is over 12 years old, we show you both numbers and let you decide. Our techs are not paid commission to sell replacements.
What brands do you service?
All major brands: Carrier, Trane, Lennox, Rheem, Goodman, Bryant, Day & Night, and more. Our trucks stock universal parts that fit most systems.
Is there a warranty on the repair?
Yes. Every repair is covered for one year, parts and labor, under the Summit Seal guarantee.
Do you offer a maintenance plan?
We do. Summit Club members get two tune-ups a year, priority scheduling, and 10% off repairs. Ask your tech for details.
