"EXCELLENT! Sent a message via Angie's List to AAD and received an almost immediate replay from owner, Kevin. Explained above and HE asked if he could come out the next morning! Arrived promptly, checked airflow and agreed something was amiss. Normally, AAD only guaranteed their dryer exhaust cleaning for 4 months, however, no charge was requested. Kevin found and showed me that the vertical air flow pipe from dryer to roof was detached from roof vent, and air was being issued to attic. Kevin re-secured the pipe to the roof vent and all was well. Kevin also asked if HE could re-clean the vent pipe with his mobile super vacuum, which he did. The pipe was clean as minimal lint found. It was outstanding display of customer service and I recommend him highly because of his concern for the customer."

"Jon was wonderful. He came out to diagnose existing issues with our AC unit. He presented us with multiple options to repair or replace the aging unit, including costs of each option. Within a week, T.Byrdâ s installed a brand new furnace and AC unit for us at a great price point. Jon and Christian worked very hard and late into the night to finish our job in one day. I canâ t say enough nice things about them or this company!"

Air Conditioning FAQs, answered by experts

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

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.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season. 

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.
