"Tommy, Justin, and Dre did a fantastic job! We had a new condenser, evaporator coil installed, replaced and upsized some of the duct runs which were incorrectly done by another contractor. Tommy, Justin, and Dre were Courteous, professional. They worked very neatly and cleaned before they left. I would definitely recommend Carolina Comfort Air for any of my future air-conditioning needs!"

"the service guys hooked a machine up to air handler and let it run for a while. They cleaned the returns and I asked them what the machine was doing, they told me it was sucking the dust out. I did not see them put anything in the main trunk lines to release the dust from the walls of the trunk line. They weren’t even going to clean the vent lines until I mentioned something about them. So they opened each vent and put a air hose with a 6 inch worn brush in each vent and only went about 6 feet in them. So I know that most of my vent lines and trunk lines didn’t get cleaned properly and for $585 bucks I thought they would do a better job."

"Dominion Services replaced my 30-year old HVAC system (the outside compressor, and the inside air handler) with a modern one having a 50% increased efficiency rating. The quality of their work is high (four friendly employees with more than 100+ years' combined experience were involved) and have good flexibility to adjust to my work schedule. They easily adapted the new system to the existing hook-ups, and were flexible in their selection among alternate, reliable replacement HVAC systems. The replacement cost was well within the range of the national average. I recommend contacting Dominion Services for insight into any HVAC issue."

"Service was knowledgable and fast, and friendly. Responded quickly to request for service and made appointment next day. Pricing so much lower than the large a/c repair companies. I am going to keep using Daughtry service for all of my a/c and heating needs."

Air Conditioning questions, answered by experts

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

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.

Some AC filters, known as reusable filters, can be cleaned and reinserted. Most AC filters, however, are disposable and cannot be cleaned. 

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.
