I noticed in our mail thing that we are due for service on our system to keep our warranty up; to do so we are actually going to do a maintenance contract with them  it is about $96 yearly, but they come out and do inspections and everything. The owner is the one who came out and gave us a quote. We had them replace another system which was nor working correctly so the first the thing they did was send someone to inspect the old system to see what were the problems. They fixed it on the spot for free and did not even charge us to come out. They were very nice, courteous and stayed in contact with us the entire time. They were very nice, professional and they got the job done in an efficient manner. They did not charge us an insane amount of money for it. We had a name brand system. It was a well worth investment to have it done right.

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

"We are new to the area and had previously hired a â top-rated company to install our thermostat. Well...they did, but we had to hire another company to come and fix their error. Johnston was that company. Knowing nothing about them, it was a risk...having already spent money for the initial install. Yet we were out at ease with the initial 730am phone call that weâ d placed for service. The tech was extremely knowledgeable and helpful, answering every question that we had and walking us through the diagnosis/repair. Excellent service all around! Would recommend them any day."

"My wife and I purchased our home (ranch 1495 sq', built in 1958) and realized it needed a lot of foundation work due to years of moisture damage. This included replacement of the main girder, 41 joists, and mold remediation. While we were at it, we let Triangle Reconstruction guide us through why encapsulation is the preferred method for eliminating our crawlspace moisture issues. So let's break down the score: Overall = A - This will be explained as I go through the other metrics Price = B - Triangle Reconstruction was competitive. They were not the cheapest, and no where close to being the most expensive. This was a $30,000 job. It was one I have never done, and hope to never do again. One of their workers even took me on a tour of the crawlspace explaining the foundation repair, the French drains, the sump pump. I was able to see how much work they did, and because of that, I felt I found a company that priced things fairly. Quality = A Work was done as expected in a reasonable amount of time. The job was permitted and the town inspector passed the project without issue. The inspector mentioned that his house is encapsulated and the work, both the foundation and encapsulation were done well. There were some minor items that I noticed, and Triangle Reconstruction was able to come back onsite an address. They worked with our schedule and completed everything to our satisfaction. Responsiveness/Communication = A The great thing is that for our project there were two people looking working with us, Drew and Rob. When we had a question and needed an immediate or quick response, it is best to pick up the phone. My wife and I were able to reach Drew or Rob without issue. We worked with Drew early on, he was our first point of contact, so we never felt uncomfortable picking up the phone an calling him. He insisted we call him with any questions. Once we met Rob, that same level of comfort was established. I mostly emailed with Rob (it was a little slower i.e. not immediate response, but more than acceptable. However, getting him on the phone was never an issue. I add that our culture's expectation to texts and emails is immediate, and those expectations should be tempered. It is important to understand that Triangle Reconstruction provides numerous avenues to contact them, and my wife and I never had an issue. So they respond to emails, to phone calls, and their crew shows up and works when they are scheduled. Scheduling with Triangle Reconstruction was relatively easy and they worked with us, and we with them. Punctuality = A They arrived in the morning, at a reasonable time (not too early), and were usually working when we got home. They did not work too late, which was comforting as I like to settle down after a day of work. I found this showed respect for our time and our home life. This was not the stereotypical experience of a contractor working like a college student goes to class. They were efficient and ultimately effective. Professionalism = A Drew - very knowledgeable, willing to follow-up and check in Rob - very knowledgeable as well, understanding, willing to take the time to come onsite and answer questions, address concerns. I felt like they were both available and genuinely cared. The crew - super nice, and respectful. I think it went well. I am skeptical of contractors, mechanics, anyone that can easily get over on me. It is important to be an informed consumer. It is important to ask questions of your contractor, and be involved in the process. Triangle Reconstruction allows this. I would hire again with hesitation. I am currently monitoring our crawlspace with humidity sensors and Rob is helping us tweak the settings as we wrap up the project. I think Rob, Drew and crew have a good thing going, and I wish them best. Update 9/19/2017 - I use AcuRite humidity sensors and noticed I had an area that was a little high, slightly above 60%. Triangle Reconstruction came back onsite, repositioned the dehumidifier and now things have improved. Rob had no issue making sure the appropriate humidity level was maintained and consistent throughout our crawlspace."

"They completed the heat pump installation work but did not come back to install a new filter rack system. I have contacted Mr Tilley three times for him to schedule the work. He came to my house but after two weeks no work has been scheduled. I am disabled and cannot change the filter without a great deal of discomfort, so I really need the work done. Update: The service took about an hour to complete."

"Chris told me exactly how it would go and that it would take about 4 hours. Well he and his co-worker finished in about 2-1/2 hours, cleaned-up and hauled all boxes and old equipment off. Very professional, knowledgeable in a lot of different areas, and punctual (shows-up on-time or calls to explain why he can't be there i.e. weather). I would definitely hire this service(s) again."

"I live way out in the sticks (40-50 minute drive) so it was great that they service homes that far out. Called ahead of time to let me know he was on his way and showed up on time. He even took his shoes off out of concern for my carpet! He was very knowledgeable, took the time to answer my questions and explain what I did or did not need. Didn't try to "get over on me" or sell me something I didn't need. I would definitely recommend them and use their services again myself."

"CHW was very responsive to our urgent need! We filed a claim the evening prior when we notices our A/C was blowing warm air into the rooms. Then by 8AM the next day, we had a call from the service technician saying he was on his way to address the issue! CHW worked with the technician to find out the compressor was the culprit and approved it's repair! Great customer service for a family in need during the hot south central Texas summer!"

FAQs for central a/c service or repair projects in Christiansburg, 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.
