Cooling Repairs

Your home’s cooling system is a complex A/C unit with a number of moving parts that all work together and helps you control the temperature inside your home. Here are some common signs you might need to have your AC unit repaired:

  • No power to your AC unit

  • Odd noises or smells

  • Home is more humid than normal

  • Uneven cooling in your home

  • AC runs frequently—or constantly

  • Leaks around your AC unit

  • Thermostat and indoor temperature don’t match

  • Surprising jump in your utility bills


Please don’t hesitate to call Diamond Climate Control Systems as soon as you notice any of these issues.

When we finish the inspection we’ll discuss recommendations, repairs, and provide an estimated cost for the heating service.  If your A/C unit is an older system we may provide some insight on the benefits of upgrading to a more energy efficient air conditioner to cool your home as well as save you money.

Cooling Installation

Most air conditioners have a lifespan of around 10-12 years. Some units you might be able to stretch a little further with regular maintenance and repairs, but eventually, it will make more sense financially to spend reoccuring repair dollars on installing a new, much more efficient unit. 

We’ll help you determine your home’s cooling needs, based on the size of your home and the number of people living there. We’ll help you find a unit that fits your budget, as well. Once that is determined we can install it correctly.

Cooling Maintenance

In order to keep your cooling system working at peak efficiency, it’s very important to make sure to have your AC regularly serviced by a professional HVAC technician. Early Springtime is the best time to get this done before the summer days start to heat up. An annual tune-up will improve the efficiency of your cooling system and keep you up-to-date with your warranty. Call or contact us today!
