"I had a power failure. Similar to a brownout. I am by no means any type of handyman. I started getting nervous so I started to call electricians. I called Wentzels went to voicemail. Call many many other electrician no luck everyone had a wait of almost a week. Another company told me to call the utility to see if it was a problem on their end. While I was on hold Justin called me from Wentzels. Told me he listened to my message and that he had someone the next town over almost done with a job. Said he could be there in 30 minutes. Andy come out. Very polite, very professional, and very knowledgeable. He was able to find the root cause within the first 5 minutes of coming out. Turns out it wasnâ t a utility problem. It was a failure in the line between the meter and the receptacle to the house. It took Andy some time but he was able to make a full repair on the spot. A+ 100% if Andy come to your project you are going to be in good hands. Highly recommend the service."

Heating and Air Conditioning questions, answered by experts
The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.
To reset your air conditioner, start by turning it off at the thermostat. Then, shut off power to the AC system at the circuit breaker. Next, find the “reset” button on your AC unit and hold it for three to five seconds. The unit should beep several times. If your air conditioner doesn’t have a reset button, leave the circuit breaker off for 30 minutes. Afterward, turn the power back on at the breaker and program the thermostat to “cool” to test the system.
The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.
No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.
One of the fastest ways to unfreeze an AC unit is to turn off the unit and, if it’s warm outside, use the fan-only mode to help blow warmer air through the unit to speed up the defrosting process. While it may be tempting to use a hair dryer to defrost the air conditioner, that high heat can damage the coils.
After defrosting, if you can safely solve the issue with a fix like changing the filter, go ahead and do so. Otherwise, call in a pro before turning your AC back on.
