Replacing an air conditioner is not something most homeowners do often. In fact, many people live with an aging system for years before deciding it’s time for an upgrade.

What to Expect During Your AC Installation

Installing a new air conditioning system involves much more than swapping out equipment. Our process is designed to help ensure your new system delivers dependable comfort and efficiency for years to come. Before installation, we evaluate duct sizing, airflow delivery, electrical capacity, and cooling load requirements to help ensure the system is properly matched to the home.

A typical D&H AC installation includes the following:

1. Home & System Evaluation

Every installation starts with an assessment of your current system and cooling requirements. We evaluate factors such as home size, existing equipment, airflow, and comfort concerns before making recommendations. If your system may still have useful life remaining, we’ll discuss AC repair options before recommending replacement.

2. Equipment Recommendations

Not every home requires the same solution. Our team explains available options and helps you select equipment that aligns with your comfort goals, efficiency preferences, and budget.

3. Professional Installation

Once a system has been selected, our technicians complete the installation according to manufacturer specifications and industry best practices. Proper installation helps support performance, reliability, and equipment lifespan.

4. System Testing & Performance Verification

Before the job is complete, we test the system to verify proper operation. This includes checking airflow, system performance, controls, and overall functionality. We can also discuss ongoing AC maintenance options to help protect your investment and support long-term system performance.

Brands We Commonly Install

Our technicians work with many of the industry’s leading air conditioning manufacturers and have experience servicing a wide variety of equipment. We help homeowners select equipment from trusted manufacturers based on efficiency goals, budget, and long-term reliability.

I’m a bit late with my review! I was very happy with my service. I had my very old swamp cooler taken out and replaced with a brand new air conditioning system. Also a mini split in another area of my house. I wanted to mention all the techs who worked most diligently during the very hot August temperature. The four techs were: Jeremy, Kaleb, Kyle and Dominque. A week later I had my ducts cleaned by Luis and Jason, another job well done. Also a shout out to Patrick who had guided me on the conversion.

We had technician Tim Caho out for a repair today. Asked for him because we found him to be trustworthy when he serviced my parents unit. He came out and got our unit in a few hours. Did little extras and went above our expectations. Will ask for him when calling D & H in the future.

Cristian, our service technician, came to the house after hours and deduced that the disconnect box was faulty. It took extra time, even after a long day, but he helped tremendously. Thank you D&H for getting my AC working again. 👏🏼

WAS very happy until today. I purchased a new AC unit two days ago. Came home today to find the unit set on cool and heat coming out of the unit! My 3 dogs were exposed to extreme heat. It is a good thing I came home when I did. I no longer recommend this company. Will update how management handles this unbelievable situation.

Technician Jacob was fixing my AC about an hour after I called the company! Jacob was so pleasant and knowledgeable. He even shared information to help prevent my AC problem from happening again. Thank you Jacob!

Tim came to replace my nest Thermostat because it wasn't working with my system. When he looked at it he felt the new Thermostat wasn't going to be any different.
He went through the current Thermostat and was able to get it working properly saving me the cost of a new one.
I really appreciated the effort to fix it rather than just replace it!

Tim did a great job in identifying the problem with the hvac unit. Should not have had to pay for the repair as it was damaged during installation.
