HVAC Capacitors & Contactors in Dallas, TX – In Stock

When an AC unit won’t start or a compressor hums but doesn’t kick on, the problem is often a failed capacitor or contactor. Open To Public HVAC Parts in Dallas stocks a wide selection of run capacitors, start capacitors, dual-run capacitors, and contactors from trusted brands like Packard and Supco — ready for same-day pickup with no account required.

Capacitors We Carry

We stock single-run capacitors, dual-run capacitors, and start capacitors in all common microfarad ratings and voltage ranges. Whether you need a 35/5 MFD 440V dual-run cap for a condenser or a 145-175 MFD start capacitor for a compressor, we have it on the shelf. Our Packard and Supco capacitors are known for reliability and longevity in the Texas heat.

Contactors In Stock

We carry single-pole and double-pole contactors in 24V coil configurations for residential and light commercial applications. Contactors wear out over time from electrical arcing — if yours shows pitting or won’t pull in reliably, we can match you with the right replacement quickly.

Frequently Asked Questions

How do I know what size capacitor I need?

Check the label on your existing capacitor for the MFD (microfarad) and voltage rating. You can also find this information on the data plate of your HVAC unit. Bring the old capacitor in and we can match it for you.

What brands of capacitors and contactors do you carry?

We primarily stock Packard and Supco capacitors and contactors. Both brands are trusted by HVAC professionals for their quality and durability.

Can a homeowner replace their own capacitor?

While capacitors are one of the more accessible DIY HVAC repairs, they store electrical charge and can be dangerous if mishandled. If you’re comfortable working with electrical components and follow proper safety procedures, it’s a straightforward swap. Our staff can offer guidance on the process.
