"We've had two visits by Core Mechanical.
One for diagnosis and customer approved temporary repair to allow time to acquire a replacement unit.
Second for replacement of faulty a/c unit.
Both occasions the service tech telephoned with expected arrival, and an updated weather delay.
Services performed quickly and with no difficulties.
Costs were as quoted.
We were happy to provide a gratuity beyond the quoted price.
We would not hesitate to recommend Core Mechanical to anyone needing their services.

"Amazing technical expertise and physical strength displayed by Mr. Hall who got the water heater to second floor by himself and safely installed my brand new unit. He's also maintained my AC for the last 7 years and recently replaced my thermostat. He is also knowledgeable and able to make electrical repairs and wiring. He is also an honest person who will advise you accordingly."

"Had called 3 other service companies with no response. Saw the Ellington AC guy at the Home Depot in Marathon and he put me in touch with his office immediately. Ellington AC actually answered the phone and sent a guy out that evening! So thankful to find a professional, courteous AC guy."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

Heating and Air Conditioning questions, answered by experts

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.
