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 Air Conditioning, Heating & Plumbing provides AC repair in Tucson and the surrounding areas for homeowners dealing with cooling system problems of all sizes. Since 1959, our team has diagnosed and repaired air conditioning issues with a straightforward approach focused on finding the cause of the problem and delivering dependable solutions. With 24/7 emergency service available, help is always within reach when your cooling system needs attention.

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.

Arizona summer is just brutal, I was having issues with my AC again. I hear the unit running but the house is not getting cold. I called D&H 24/7 service. They were able to fit me in the same day (Saturday). Giovanni did the inspection, he took photos and run diagnostics so he can explain it better. This was a same day maintenance service so hoping not to have a lot of issues. The problem was the capacitor (about 3 years old)that needs to be replaced. The issue was resolved and AC is working properly especially with 105 degrees heat. I definitely recommend D&H service. Giovanni did a phenomenal job, absolutely satisfied and I highly recommend D&H.
I also wanted to extend my thanks for Giovanni for bringing up a gas smell and having us reach out to Southwest Gas to do a courtesy check. They eventually came out and fix the leak. His attention to detail and priority to safety is above and beyond. Thanks you Sir.

I know I have posted several times about this business, but when you have locally owned company that provides phenomenal service you need to put it out there. Had a simple issue I could have probably fixed, but called a technician out anyways. Ethan showed up and took the time to explain what to do next time as it was an easy fix. However the way he explained what happened was fantastic. D&H has always sent employees that are respectful and treat customers to where they don't feel dumb for asking questions. Again. All around great service from dispatch to Ethan taking of of the customer on his end. Can't recommend enough.

Our central air went out last night. D&H was here before 10 am and had the unit running full blast by 10:30. Kudos to Isaiah who was up on the roof but also to the front office, who we found to be very cordial.
