"Talked to a lot of companies. Mike was about as dte & real as you get. Immediately got good vibes. He sent his 2 son's out to check out my AC unit outside. I'd gotten varying opinions & estimates. Tbh, I became weary, but I figured Mike wasn't feeding me anything but what was real. His boys showed on time, extremely polite, well mannered, knowledgeable & professional. They went right to work. Found the problem without trying to sell me a bunch of extra stuff or pad the price for something it didn't need. Without hesitation, I said do it! I have to admit for 2 very young guys, they knew what they were doing. When they were done fixing my system was cranking it out & putting like a kitten. I was afraid out what my bill would be. Couldn't believe how fair & reasonable it was. No extra fees, taxes, add ons etc...EXTREMELY IMPRESSED...I definitely found a HVAC + Co on the Eastern Shore I trust and highly recommend them. Family business & it shows with pride they take it seriously..."

Small jobs welcome

"I hired this father-son team to repair my deck...the floor was sagging and damaged by original insufficient room between boards for drainage. They pointed out several problems; discussed all surprise irregularities, fixing unforeseen safety issues with suggested ideas and outcomes. They were dedicated, punctual, professional, and personable while doing an excellent job. Rain didn't stop them; they put up a canopy, and continued working until the area got too wet to safely use the electric power tools. Their work was precise with dedication to detail. My choice will always be precision and quality over speed."

Air Conditioning questions, answered by experts

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

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.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Yes. It's normal for the AC compressor to cycle on and off intermittently in dry mode as it maintains the desired humidity level. The compressor cycles to prevent over-dehumidification and to maintain a comfortable indoor environment. This cycling behavior ensures efficient operation and optimal humidity control, contributing to the overall effectiveness of the dry mode function in your AC system.
