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.

( 14Oct26) Tim just did a Family Plan check on the gas heater, found a small leak with his nose and a detector, fixed it. In and out in less than a 1/2 hour. He explained every step. I feel confident that we will have a working system during the cold months.

Tim Caho with D&H did a great job repairing my heat pump. I appreciated his honest advice about the risk associated with repairing an old unit like mine. I decided to assume the risk and go ahead with the repair. Tim’s years of experience were evident as I watched him replace the faulty parts. I tried not to bother him too much as he worked, but he patiently answered all my questions while navigating the tangle of wires and components. It was a pleasure chatting with Tim. I feel lucky they sent me him.

New 5 -star review!
Tim Caho was out again for a new problem on a different heat pump unit this time. The outside condenser unit was being disabled due to a blocked condensation drain pipe. The air handler's emergency water pan was full and thankfully the float switch worked to disable the outside unit. Tim had to suck it out with a shop vac (two 5 gallon buckets worth! and not easy because the air handler is in the attic space). There was no drain pipe connected to the emergency pan (not up to code) and the P-trap on the main drain was made up with 90 degree bends in the PVC making it impossible to clean with a pipe brush. Tim installed a new drain pipe on the emergency pan and also replaced the P-trap with a clear plastic curved P-trap with serviceable ports so you can see any sediment build up and it can now be cleaned with a brush he provided. Another 5 star job by Tim!

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.
