"Service man arrived promptly. Quickly diagnosed the problem, replaced a contactor ($25.00 item) and replaced a capacitor ( a $15.00 item). This work took about 30 minutes. Charged $478.00. I think this was extreme overcharge."

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"We have lived in our home for 12 years and decided to have the home inspected (just to make sure that we weren’t missing anything that was wrong). After we received the inspector’s report regarding the problems in our crawlspace, we contacted Triangle Reconstruction. They came out promptly and spent a considerable amount of time assessing the situation and getting to the ROOT cause of the problems. As a matter of fact, they discovered each and every issue that the inspector found without having had any details of the report. They provided an itemized quote and gave us their opinion as to which items were absolutely necessary, which were “nice to have” and which we could do on our own. We were notified as to when each and every phase of the job would start and end. Triangle Reconstruction brought in different teams of experts to complete the work. This made the job progress quickly and efficiently. After each team finished, a supervisor would come to inspect their work. I highly recommend Triangle Reconstruction. This company runs like a finely tuned orchestra. They are professionals in every sense of the word and their work is impeccable!"

"It went very well from the moment I called Tilley's to the moment the technician left. The technician arrived at the house a few hours after I called.  Two other companies would not have been able to look at the unit for several days (one of them a week later). 
Very professional and knew what he was doing.  I will definitely use Tilley's again in the future.

"The repairmen were on time, very knowledgeable, and efficient. I am putting their phone number in my book so I can contact them if I ever have another problem. Not only were they very good, but the price was really reasonable. This is the first time I have used Home Advisor to find help, and I will definitely use them again!"

FAQs for central a/c service or repair projects in Blacksburg, VA

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
