Most heating systems spend months sitting idle before they’re suddenly expected to perform when cooler weather arrives. Without routine service, wear, dust buildup, and small performance issues can go unnoticed until they affect comfort or lead to a repair call. Regular maintenance gives your system the attention it needs before the heating season begins.

At D&H Air Conditioning, Heating & Plumbing, we believe maintenance should be proactive, not reactive. Since 1959, Tucson homeowners have relied on our team to help keep furnaces, heat pumps, and other heating systems operating reliably through thorough inspections, performance testing, and preventative care.

Call D&H Air Conditioning, Heating & Plumbing or reach out online today to schedule heating maintenance or a heating system consultation.

Services Included in Heating Maintenance

A maintenance visit gives your technician time to check how the system is running, look for wear, and make sure important parts are working as they should. During heating maintenance, D&H may perform services such as:

System Performance Testing

We check how the heating system starts, runs, and responds to thermostat settings. Performance testing can help identify issues that may not be obvious during everyday operation. It also provides insight into the overall condition of the system.

Furnace & Heat Pump Inspection

Our technicians inspect furnaces and heat pumps for signs of wear, damage, and developing problems. Early detection can help prevent larger repairs and unexpected breakdowns. We also evaluate overall system condition during the inspection.

Airflow Evaluation

Proper airflow is essential for comfort and heating performance. We check for restrictions or issues that may affect how warm air moves throughout the home. Addressing airflow concerns can help improve system operation.

Filter Review

A dirty or clogged filter can reduce airflow and place additional strain on the system. During maintenance, we inspect the filter and discuss replacement if needed. Clean filters support better system performance and indoor comfort.

Safety Checks

Our team looks for concerns that could affect safe system operation during the heating season. These checks help verify that the equipment is functioning as intended. Safety remains an important part of every maintenance visit.

Maintenance Recommendations

If we identify an issue, we’ll explain what we found and answer any questions you may have. Our technicians provide straightforward recommendations based on the condition of the system. The goal is to help you make informed decisions about future service needs.

Benefits of Routine Heating Maintenance

Routine maintenance helps homeowners stay ahead of problems that could affect comfort, efficiency, or system reliability. A well-maintained heating system is less likely to experience unexpected issues during cooler weather and gives technicians an opportunity to identify concerns before they lead to larger repairs. Regular service can also support better system performance, improve energy efficiency, and help extend the lifespan of heating equipment.

For homeowners seeking ongoing system care, D&H offers a Family Maintenance Plan that includes scheduled service and additional benefits to help keep heating and cooling systems operating at their best year-round.

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.
