"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."

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

Heating and Air Conditioning questions, answered by experts

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

Assessing location for airflow, convenience, and minimal noise impact.

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.
