An air conditioner rarely chooses a convenient time to break down. It might stop cooling during a summer afternoon, begin making unusual noises in the middle of the night, or struggle to keep temperatures consistent from room to room. No matter the issue, prompt repairs can help prevent additional system damage and restore comfort faster.

D&H AC Repairs We Offer

Air conditioning systems rely on multiple components working together to keep your home comfortable. When one part begins to fail, it can affect performance, efficiency, and reliability. D&H repairs a wide range of cooling system issues and works to identify the source of the problem before recommending a solution.

Refrigerant Leak Repair

Low refrigerant levels can reduce cooling capacity and make your system work harder than necessary. Our technicians locate leaks, complete the necessary repairs, and restore proper refrigerant levels. Addressing refrigerant issues promptly can help prevent additional strain on the system.

Thermostat & Electrical Repairs

Thermostat malfunctions can prevent your air conditioner from operating correctly. We repair issues involving wiring, capacitors, contactors, relays, and other essential components. Accurate diagnostics help ensure the correct repair is made the first time.

Blower Motor & Airflow Repairs

Poor airflow can make it difficult to maintain consistent temperatures throughout the home. Problems may stem from blower motors, fan components, clogged filters, or airflow restrictions. Our team inspects the system thoroughly and performs repairs designed to restore proper air circulation.

Repairs Vs. Replacements

Not every air conditioning problem calls for a new system. In many cases, a repair is the most practical and cost-effective solution. Our technicians take the time to evaluate the condition of your equipment, explain what they find, and provide straightforward recommendations based on the system’s performance, age, and repair history.

If a repair makes sense, we’ll tell you. If a replacement would provide better long-term value, we’ll explain why and discuss your options for AC installation. Our goal is to help you make an informed decision that fits your home, comfort needs, and budget without pressure or unnecessary upselling.

( 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.
