Air conditioning is an essential tool for combating the heat and humidity that the summer weather brings to the Concord, NC area. And thankfully, many modern advancements in AC technology have made today’s air conditioners more powerful and more effective than ever.

At Dulin Mechanical Services, Inc., our job as an HVAC contractor is to see that you have access to the highest-quality summer cooling products and services available. We fulfill that responsibility by providing air conditioning solutions sourced from reputable and innovative HVAC manufacturers and offering hands-on AC installation, maintenance and AC repair services that are performed by highly qualified air conditioning service technicians.

New & Replacement AC Installation Services

Whether you are replacing your worn-out AC system, doing a home remodel and AC equipment upgrade, or installing a brand new air conditioning system in your new home build, our HVAC installation experts can help. Our experienced AC installers have been carefully trained to follow the proper installation protocols to ensure that your ac repair or installation is done right. This means that whether we dispatch a single installation technician to replace your current air conditioner or send an entire installation crew to handle your new-construction HVAC system install, you can depend on us to give your job the care, attention and skilled workmanship it deserves.

New-Construction AC Installation

Our new-construction project managers have received extensive professional training that has thoroughly equipped them to oversee every step of your AC installation — from determining load calculations to system placement and everything in between — for the highest-quality outcome possible. With more than 15,000 successful HVAC installations to their credit in our service area, our project managers and installers have amply demonstrated their ability to get our customers' systems in and running correctly and on schedule.

From the moment your project manager takes over your installation, you can be sure that the focus will be on helping you choose and get the system in place that will most closely match your needs and budget. We handle selection, sizing, design, layout and final installation of your system. The goal is to ensure that the system you choose will be the perfect one for your home.

AC Repair Services, Including After-Hours Service Repairs

Many things can go wrong with your AC system — some minor and some major. Either way, you'll benefit from knowing you have the fully qualified repair technicians at Dulin Mechanical Services, Inc. waiting in the wings to provide their expert assistance. Anytime your air conditioner acts up, give us a call. We'll respond promptly and have you back up and running in no time. Here are some signs that could indicate that your AC system needs attention:

  • Unusually noisy air conditioner operation
  • Sudden, higher-than-normal indoor humidity
  • Strange odor coming from the vents or the unit
  • Repeated on/off cycling with inadequate cooling
  • Low airflow or air that's not as cold as usual
  • Apparent water leakage around the AC unit
  • Uneven cooling in different parts of your home

Whatever air conditioner issue you face, give us a call. You can count on us to provide the expert repairs you need to restore your indoor comfort.

After-Hours Emergency Air Conditioning Repair

In addition to the regular repair services we offer, our After-Hours AC repair service helps ensure that no matter when your air conditioning emergency happens, you have help available. When your AC system breaks down unexpectedly after-hours in the heat of summer, you can rest assured that we've got your back. Simply call our office, and we'll dispatch a qualified emergency service technician as soon as possible.

AC Maintenance Services & Preventive Maintenance Agreements

One of the best ways to arm your system against unexpected breakdowns is to keep it well-maintained. That means changing your air filter once a month and having your system professionally inspected annually before each cooling season to make sure it's clean, tuned, safe and running as it should. Regular AC maintenance is not a luxury. It's an air conditioning service you can't afford to ignore.

We keep your Charlotte, Concord, Harrisburg, Midland, NC, or surrounding area air conditioner well-maintained, so you can save a great deal of money on utility bills, repair bills, and system replacement costs. Regular air conditioning service such as an annual AC tune-up helps minimize wear and tear on your system, increases system efficiency, and can often catch developing problems and safety concerns before they become more serious.

Our Preventive AC Maintenance Program

To make it easier for you to make AC maintenance a normal part of air conditioner ownership, we offer the convenience of our Preventive Maintenance program. With our affordable Preventive Maintenance Agreements, you'll enjoy priority customer status on emergency service calls and a 15 percent discount whenever you need repairs.
