Air Conditioning Repair Services

preventive HVAC maintenance

For areas with hot and humid summers, a malfunctioning air conditioner can impact health and safety of the elderly, children, and people suffering from chronic illness. Time is a critical factor when a system breaks down, and it is important to hire an HVAC contractor who responds quickly to service inquiries and communicates regularly through the repair process.

For every home heating and cooling repair, we dispatch technicians who have experience servicing virtually any brand or model of air conditioning equipment. Their knowledge and expertise will help reduce downtime and keep the cost of the repair to an absolute minimum.

When you need an AC repair, and fast, call the experts at Black Diamond Plumbing & Mechanical.

AC Installation & Replacement

Accumulated heat stress will degrade air conditioning performance over time. When repair costs begin to rise and indoor comfort is compromised, it may be time to consider an AC replacement. Homeowners with systems that are more than ten years old may benefit considerably from the purchase of a new, efficient Bryant air conditioning system. In fact, replacing a 10 SEER air conditioning unit installed in the early 2000s with a modern 16 SEER system can save up to 60 percent on annual cooling costs.

When you’re looking to install a new cooling unit in your Illinois home or office, count on the experts at Black Diamond. Our professional technicians ensure that your unit is properly and safely installed so you can guarantee it will have a long and healthy life.

Preseason Tune-ups & Maintenance Agreements

Regular service helps keep home cooling and heating equipment operating at peak efficiency. A maintenance agreement can expose minor problems before they can affect system performance. Our factory-trained and NATE-certified technicians visit the customer’s home or business on a seasonal basis and perform a variety of important AC services that can help lower monthly utility costs, extend the system’s life, and improve indoor comfort.

Routine maintenance is so important that it is a provision of every major manufacturer’s warranty coverage. For an introduction to the numerous benefits of preventative maintenance, we recommend a preseason tune-up, which provides many of the same services as a maintenance agreement without the long-term commitment.

Crystal Club Maintenance Plans

Because we strongly believe that your HVAC unit should be inspected once per year, we have a whole membership program which brings discounts and special services to those who join. When you are a member of our Crystal Club, you can benefit from:
