Air Conditioning Services

The temperatures in Diablo can get well into the 90s and above during the summer, and even the cooler months can see heat waves. Rely on AIS when you need AC services for your home or business. We offer:

Signs You Need To Replace Your AC

Air conditioners typically last for 12 to 15 years if they’re well-maintained. Signs you should consider replacing your air conditioning system include:

  • Advanced system age
  • Repair costs that are over 50% of the unit’s value

Is your Diablo home or business ready for the next cold snap? Turn to AIS for all your residential and commercial heating service needs, including:

Common Heating Problems AIS Repairs

Our team can resolve any issue with your gas or electric furnace, including:

  • System short-cycling
  • Noisy operation
  • A yellow or extinguished pilot light
  • Dirty filters

Heat Pump Services

Heat pumps are designed to move heat from inside the house to the outdoors or vice versa. These units move heat to create a warm or cool space inside your home, providing the same comfort as an air conditioner and furnace.

Whether you need your heat pump repaired, want to install a new heat pump, or need to schedule routine heat pump maintenance, look to AIS to handle the job.

Ductless Mini-Split Services

Ductless mini-splits are the ideal HVAC solution for precise comfort that you can customize to individual zones. Whether you have a home addition, a two-story home, or a home without ductwork, mini-splits are a great option.

We offer a full selection of ductless mini-split services, including:

Mini Split Vs. Heat Pumps: Which is Better

Should you install a series of mini-splits or a whole-home heat pump to warm and cool your home? It’s a big decision, but there are things to consider before making a choice.

Mini-splits feature an indoor unit and an outdoor compressor. They can provide heating or cooling for a single room and be set up into a zoning system with other mini-splits.

Heat pumps transfer heat from one space to the other to create a cooling or warming effect. These systems can heat or cool the entire home through the air duct system or without air ducts.

Our team can discuss your needs and install the right HVAC system for you.

Indoor Air Quality Services

Your home’s air can have a major effect on your health. Ensure that your family breathes the cleanest air possible with indoor air quality services from AIS.

We offer whole-home humidifier and UVC air purifier installation.

Ductwork Services

Sometimes, the biggest cause of your HVAC issues isn’t the units themselves — it’s the air ducts.

At AIS, our air duct services include:

  • Ductwork installation: Your duct system will be designed and installed to fit your home.
  • Duct sealing and repair: We’ll restore cracked and leaky ductwork so no air escapes before it reaches your vents.
