"I posted an urgent plumbing job on Angi and heard from a couple of pros within about an hour. Andy from AS Plumbing & Heating was the first to give me an estimated arrival time and asked for photos beforehand so he could better understand the issue. He arrived exactly when he said he would, quickly identified the problem, explained everything clearly, and completed the repair efficiently. He was friendly, professional, and kind throughout the visit. His estimate was reasonable, and he even reduced the final cost as a thoughtful gesture. I wouldn’t hesitate to recommend AS Plumbing & Heating and will definitely contact them again for future plumbing work."

"Jeff did an excellent job. I could not be happier. He determined the issue and installed new parts and my A/C was up and running during this summer heat wave. He took the time to explain what was going on with the unit and what needed to be fixed. Very friendly and honest. Highly recommended."

Heating and Air Conditioning questions, answered by experts

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

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.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.
