"Ephraim cleaned the dryer and dryer vent efficiently. We then spoke at length about our HVAC system and cleaning the ductwork. Efy found mold in our system air handlers, made suggestions for taking care of the issue, and cleaned the ductwork. He was terrific... knowledgable, and efficient!"

"Quality of work seemed high until parts of floors came unglued, grout chipping in shower, areas missed paint in garage. 6 week project turned into 10+ weeks, WAY OVER PRICED! Sometimes workers wouldnt show the entire week. Had to have dry wall workers come back multiple times because they didn’t take mirrors or towel racks down just worked around them. Workers were nice and polite when at the house. Tons of miscommunication between myself and contractor. Very frustrating remodel job."

"I would highly recommend this business.  We had them come and restain the deck and at first just powerwash the house.  They scheduled the work right away.  After doing the pressure washing, there were some areas with paint chips under the soffit.  Mike offered to repaint those for free.  During this, they noticed areas of the soffit that were rotten, so we had them repair those areas of the wood.  They also fixed a few screens that were damaged during the pressure washing for free.  
Everything turned out great, and we are very happy we had this work done.  Mike and Crystal are very professional and easy to work with.  I will be having them do some more work on our house in the near future.

FAQs for window a/c unit service or relocation projects in Charleston, SC

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
