"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..."

"We were extremely happy with our recent service. We really liked that he showed us the aspects of our dryer and vent and how we can keep it clean on a weekly basis. He was very tidy too! I would definitely recommend him and plan to have him return each year."

Air Conditioning FAQs, answered by experts

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

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.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
