"After I spent $500 on Freon two weeks ago my A/C is not working again. The person in the office said I have a freon leak, but the tech never informed me about that. I would have never had him add freon, if it was leaking. The tech didn't give me a copy of the invoice I signed, he said he would email it to me. Never received the email & all of the sudden the invoice states I didn't want the leak repaired which Tech never mentioned. The invoice only showed the price. ***Beware this must be their way to get you to spend more money*** SCAM***I will let my family, friends, neighbors, and coworkers know how they do business."

"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day.

"Absolutely outstanding! I have used Mike and Charles and their company since they started business and I do not believe that anyone could do a better job installing and maintaining the three HVAC units in my home and my wife's art studio. As part of my total remodel of my home, they replaced all the HVAC ductwork and, over time, replaced all the units for more efficient ones. Believe me, the house was cleaner and our electric bills were substantially lowered. They will come out on holidays and weekends when you need them. They have come out on the 4th of July and at midnight--these instances when the builder supplied house units broke down and before they replaced them. They have always been courteous and professional as have all their employees. I hope I can find HVAC professionals as competent and efficient as they are when I complete my move to Johns Island. I will leave my home buyer with a paid up maintenance contract for the next year and I am confident they will continue with Blythewood Heating AC & Refrigeration."

Heating and Air Conditioning questions, answered by experts

Turning off your AC may temporarily stop your unit from leaking water unless the leak is from a thawing coil that continues to thaw after the system is shut off. Regardless, it helps to discontinue use of the unit if it has a leak in order to figure out what’s causing the issue.

If your AC refrigerant is low, you may notice that the unit takes longer than usual to cool your home or that your energy bills are higher. You may even feel a warm breeze coming from the vents when the AC refrigerant is low. Don’t attempt to check refrigerant levels yourself. Only certified AC repair pros should check and refill refrigerant.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

A dirty air conditioning coil can cause your unit to work overtime, leading to reduced efficiency, higher energy use, more wear and tear, and possible ice buildup. If the coils corrode, refrigerant can leak, causing damage, possible mold growth, and an expensive repair bill. By cleaning your AC coils once a year, you’ll have a more efficient unit that’s likely to last longer.

High humidity is one of the most common reasons for air vents to sweat or produce condensation. When the cool, dry air from your HVAC unit meets warm and moist air in your home, it will cause condensation. Insulating your ductwork can help prevent this. If you live in a very humid region, a dehumidifier can also help.
