"I had the misfortune of hiring Lion Enterprise to fix my PTAC. I called them to replace a burned power cord as diagnosed by my electrician who came to replace my kitchen light fixture. They came but did not bring a power cord with them. They had to return the next day and took less than an hour to replace it. 2weeks later, their office called and asked for the cc number as they had the wrong number. I asked them how much it will cost, they said $275. + tax.I agreed. Later, they charged my card $489.94. I called, they told me the guy who quoted $275 did not know and they refused to compromise. Charging more than what was permitted is fraudulent and amounting to theft. Caveat Emptor, do not entrust them with your cc number. Ask for a bill and then authorize the payment. A lot of crooks there."

Heating and Air Conditioning questions, answered by experts

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

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.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.
