Most homeowners don’t think much about their air conditioner until something goes wrong. The reality is that many common cooling problems begin long before there are obvious warning signs. Routine maintenance gives technicians the opportunity to identify wear, check system performance, and address minor concerns before they develop into larger repairs.

As part of our air conditioning services, D&H Air Conditioning, Heating & Plumbing provides professional AC maintenance designed to help homeowners protect their comfort systems and prepare for the demands of the cooling season. Since 1959, our team has helped homeowners keep their systems operating efficiently through regular inspections, tune-ups, and preventative care.

Benefits of AC Maintenance

Air conditioning systems operate under demanding conditions for much of the year. Routine maintenance helps keep equipment operating efficiently while reducing unnecessary wear on critical components. Benefits of regular AC maintenance may include:

  • Reduced risk of unexpected breakdowns by identifying developing issues before they become larger repairs.
  • Improved energy efficiency through proper system operation and airflow.
  • Longer equipment lifespan by reducing unnecessary wear on critical components.
  • More consistent indoor comfort and cooling performance throughout the season.
  • Greater confidence that your system is prepared for periods of heavy use.

What Does AC Maintenance Include?

A maintenance visit involves more than a quick inspection. Our technicians evaluate key system components, verify proper operation, and look for signs of wear that could affect performance or reliability.

System Performance Testing

We test system operation to verify that major components are functioning properly. This includes checking temperatures, airflow, controls, and overall cooling performance. Performance testing helps identify issues that may not be noticeable during everyday use.

Component Inspection

Our technicians inspect important system components for signs of wear, damage, or deterioration. Identifying developing issues early can help reduce the likelihood of unexpected repairs. These inspections provide valuable insight into the overall condition of the system.

Cleaning & Efficiency Checks

Dust and debris can affect airflow and system efficiency over time. We inspect and clean accessible components as needed while checking factors that may impact performance. Keeping the system clean helps support reliable operation throughout the cooling season and prevents the need for expensive AC repairs in the future.

Maintenance Recommendations

At the end of the visit, our technicians discuss any concerns they find and answer your questions. If additional service is recommended, we’ll explain the issue clearly and provide straightforward guidance. Our goal is to help you make informed decisions about your system’s care.

( 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.
