AC Repair, Maintenance, and Installation

The weather in Rock Hill can often be extreme, with summertime temperatures routinely reaching 90 degrees or higher. With that in mind, you need to keep your air conditioner running at its best all summer long. One of the best ways to achieve that is to invest in annual AC maintenance. The benefits include:

Another good way to keep your AC running at its peak is to schedule repairs at the first sign of trouble. Some signs of an AC that needs to be repaired include:

In some instances, you may be better served by having your air conditioner replaced. Our team will help you understand what’s wrong with your current system and guide you through the process of choosing between AC repair and replacement.

Heating Repair, Maintenance, and Installation

While summertime temperatures often soar above 90 degrees Fahrenheit, wintertime temperatures have the potential to dip below freezing. Having a quality home heating system is crucial when temperatures reach their lowest. Fortunately, you can schedule heating service with our team to make sure that your home is cozy and warm all winter long.

Instead of waiting for something to go wrong with your home’s heating system, scheduling routine maintenance is a great way to keep it running at its best. During a maintenance visit, one of our certified technicians will thoroughly inspect your heater to make sure all the parts are well-lubricated and working properly. This allows us to address any potential issues before they turn into breakdowns.

In some cases, installing a new home heating system may be your best option. Fortunately, there are some benefits of investing in a new heating system, including:

Of course, Dilling is always here if your heater breaks down. Over the years, our team has encountered virtually every kind of home heating issue, and they’re well-versed in performing repairs, no matter the make or model.

In addition to installing a new furnace, our team can also handle all of your routine maintenance and furnace repair needs. When wintertime comes and temperatures reach their lowest point, let us keep your home safe, warm, and energy efficient.

Indoor Air Quality

Since you spend more time inside your home than anywhere else, it’s important to protect your indoor air quality (IAQ). Unfortunately, the EPA reports that the air inside a typical home may be up to five times dirtier than the air outside. If you notice any of the following signs, you should invest in IAQ solutions:

If you’re unsure about the IAQ in your Rock Hill home, schedule an indoor air quality test with us.
