Air Conditioner Repair FAQs

What air conditioner brands does Black Diamond service?

We proudly service all air conditioner brands.

How often should an air conditioner get regular maintenance?

When in frequent use, you should change your filter and inspect/clean your air conditioner once a month. However, we highly recommend scheduling a professional tune-up once a year.

How can I check if the air conditioner is still under warranty?

Most companies will allow you to verify your warranty coverage through their website or by calling their customer service department. So don’t worry if you’ve lost the paperwork that came with your unit.

Is a bigger air conditioner a better air conditioner?

No. Bigger isn’t always better. If your AC is too big for your home, you won’t enjoy the cost savings and energy efficiency of an appropriately sized unit. If your AC is too small for your home, it will struggle and work overtime to keep you comfortable. This will increase wear and tear on the equipment.

If you’re considering getting a new HVAC system, we highly recommend having one of our comfort consultants visit and recommend the best options for your home and budget.

Why isn't my house cooling off?

There are several reasons this could be happening. You could have a blocked condenser unit, a clogged refrigerant coil, blockages in your ducts, or a thermostat issue.

Why is my air conditioner icing up?

AC systems can ice up when dirty air filters block air from moving over the refrigerator coil. In most cases, changing the filter resolves the problem.
