"Sean was great about repairing my disconnected dryer air duct having to go into the crawl space and figure out what was going on. I'm glad he was able to get it done very quickly as well. He also had a very good attitude about doing the work."

"Tyler Jones from All City Plumbing Air and Electrical did a great job replacing a gas valve in our garage. He was friendly and easy to engage with, clearly knowledgeable, and took the time to explain what he was doing. The work was completed efficiently and effectively, and everything was handled professionally from start to finish. I’d definitely recommend Tyler and All City for plumbing and gas-related work."

"Chris came by for a normal AC tuneup and as he was finishing up, we told him about some issues with our dishwasher and master bathroom sink and asked if he knew a plumber. He took care of both our problems right then and there! I’m not sure there’s anything he can’t fix. Chris is our go to guy for EVERYTHING ac/furnace/plumbing and he should be yours too!"

Air Conditioning questions, answered by experts

One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.

After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.

AC drip pans last five to 20 years, depending on the material. Plastic AC drip pans last five to 10 years, while metal pans can last over 10 years. Plastic AC drip pans are vulnerable to cracking in response to temperature changes. Metal drip pans are prone to rusting over time, which can also lead to leaks.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.
