Your drain is slow again.

Why does this keep happening?

If the same drain keeps slowing down, there’s probably more going on than what you can see at the drain opening.

A recurring clog can mean:

Buildup is still inside the pipe. A quick fix may get water flowing again without removing everything causing the restriction.
Debris keeps catching in the same spot. Grease, soap, hair, and other buildup can create a cycle of repeated clogs.
The blockage may be farther down the line. The issue isn’t always located where you notice the slow drainage.
There could be a plumbing issue behind the recurring clog. Persistent blockages can sometimes point to a problem with the drain line itself.

If you’ve already cleared the same drain more than once, don’t just keep treating the symptom. Find out why it keeps coming back.

D&H Air Conditioning & Heating & Plumbing can take a closer look at the drain, explain what’s causing the problem, and recommend the appropriate fix. 📞 520-477-4564

Tankless or traditional water heater? The answer isn’t just about the type of system.

Hard water can leave behind mineral buildup as water moves through your plumbing and water heater. Over time, that buildup can affect performance and the maintenance your system needs.

And the way it affects a tankless water heater isn’t exactly the same as a traditional tank water heater.

If you’re considering a new water heater, it’s worth knowing how your water quality factors into that decision.

We break down the differences, maintenance considerations, and what to keep in mind before choosing a system.

Yes. Even if your heat only gets used a few times a year, it still needs to be ready when you need it.

Your heating system may sit unused for months, but that doesn't mean you should wait until a cold night to find out if it's working properly.

Before that happens, pay attention to how your system starts up:

Does it turn on normally?
Is the airflow strong?
Are there unusual sounds or odors?
Does the home actually warm up?

A heating check can also help identify issues with airflow, electrical components, controls, and other parts of the system before you depend on it.

Get your heat checked before you need it. Schedule with D&H Air Conditioning & Heating & Plumbing. 📞 520-477-4564

It’s a simple way to give your heating and AC the attention they need throughout the year.

Arizona's cooler mornings and evenings are here, which means your heating system may be getting its first workout of the season.

The first time you switch your thermostat to HEAT, don't just make sure warm air comes out. Pay attention to how the system starts and runs.

Watch out for these 4 things:
• Unusual Smells
• Strange Sounds
• Weak or Uneven Airflow
• It Runs, But Doesn't Warm Up

A brief dusty smell can happen when the system hasn't run in months. But if something seems unusual or different from what you've experienced before, it's worth finding out why.

Not sure if what you're noticing is normal? D&H can take a closer look, explain what we find, and help you understand what needs attention. 📞 520-477-4564
