24/7 emergency AC repair for when you need it most

 

An air conditioner never breaks down at a "good" time. It's always on the hottest day of the year, after hours, or on a weekend. In the Tri-Valley, going without AC for even a few hours can be unbearable and even unsafe for children, the elderly, or pets.

​

Don't wait and worry. Call Service Star HVAC right away if you notice:

• Warm air blowing from your vents

• Strange noises like grinding, squealing, or clanking

• Sudden leaks or moisture around your indoor unit

• Your system turning on and off constantly (this is called "short-cycling")

• A sudden spike in your energy bills​

We have a technician on call 24 hours a day, 365 days a year. Our trucks are stocked with the most common parts, so we can often fix the problem on our very first visit and get your cool air back on fast.

New air conditioner installation and replacement

 

Is your old air conditioner costing you a fortune in repairs and high energy bills? It might be time to consider an upgrade. But how do you know if you should repair or replace it? We’ll help you make an informed, pressure-free decision.

​

Our comfort specialists will inspect your current system and discuss your needs. We’ll recommend a modern, energy-efficient air conditioner or heat pump that fits your home and your budget.

 

A new system might provide:

• Lower Monthly Energy Bills: Modern AC units are far more efficient than models from 10-15 years ago.

• Quieter Operation: Enjoy the cool air without all the noise.

• Improved Indoor Air Quality: Better filtration means cleaner, healthier air for your family.

 

We'll take care of the installation, hauling away of your old unit, permitting, and any duct work upgrades required. Ready for a new system? Call us today (925) 369-8100.

Frequently Asked Questions (FAQs)

 

Do you offer 24/7 emergency AC repair? How quickly can you get here?

Absolutely. We offer 24/7 emergency service because we know AC problems don't stick to a 9-to-5 schedule. We prioritize emergency calls to ensure a fast response, especially during extreme heat, to get your system back up and running as quickly as possible.

​

How do I know if I should repair my AC or replace it?

We typically look at a few factors: the age of your system (if it's over 10-12 years old, replacement is often more cost-effective), the frequency of repairs, and the cost of the current repair. If a repair costs 40-50% of a new system, we'll usually recommend replacement. We'll give you an honest assessment so you can make the best choice. What ever you choose, we are happy to help.

 

What types of air conditioning systems do you service and install?

Our knowledgeable technicians can work on all of them! We install and service central air conditioning systems, ductless mini-splits (perfect for homes without ductwork), and heat pumps. We can also help you with modern upgrades like smart thermostats to improve your home's efficiency.​​
