"I would highly recommend Druziako HVAC Co. to anyone needing repairs and or replacement for Heating and cooling service. We lost our furnace Heating in the middle of the cold snap, these guys came out and immediately found the replacement system we needed and promptly replaced the next business day. Job completed, who does that..? The owner even called us during the night and offered to bring us a temp heat source if we needed it. Fortunately we did not. We can't say enough about the service. I would use them again and plan to for future cleaning and service. Nick ( the Owner i guess) and his guys did a great and professional job. Thank You Nick...!"

"My Central AC unit went out; the box outside smelled like something had fried. I called NETR, and they said they would send a technican over in a week. The technician came on time and promptly inspected the unit. He reported that the capacitor had blown, and told me that he had a spare back in his van. The labor was covered by the diagnostic site visit fee, it was just the parts cost. I told him to proceed and he replaced it. My AC was back up and running within the hour."

"Terrific experience. Scheduling was easy. My technician, Guy, gave me a call ahead of time, hit the time he said he'd be here and was courteous and efficient. I ran a large mechanical contracting business for years so understand this business. Guy ran through his checks on what is a fairly complex home system. He pointed out problems that were minor, major, or had the potential to be major. We discussed options and timing. Since our system is old, it will be difficult to repair some of the parts and pieces while others would be fairly standard. We may want to look at a new system this summer to avoid a major problem during a future heating season. I will definitely be talking to Sila."

"My central AC unit has been broken for several years. intermittently working during hot summers. I've had several HVAC companies come to diagnose and all of them told me different things: replace the whole system, new lines, etc. potentially costing tens of thousands of dollars. So I decided to troubleshoot by myself and pinpointed the issue: the filter dryer needed to be replaced. No company wanted to do this small job. I called Emerald HVAC and told them about my issue, they sent in José, who diagnosed the issue to be what I said. He replaced the filter dryer and the AC unit works perfectly now after several years! In short, Emerald HVAC will be my first choice for any HVAC work in the future. They are honest, professional, and reasonably priced. I recommend them without reservation!"

"The repair went well. Our HVAC system would not turn on so Mike showed up earlier than scheduled (I was called first for the ok) and got right to business. He found the problem- a blow fuse in the unit itself. Once he replaced the fuse the system still would not turn on, but the circuit board that runs the system did light up. he checked out the electrical to make sure there was not a short that caused the problem. It seemed baffling as to the issue so he went outside and checked to see if the electrical issue was at the compressor. Sure enough an animal had chewed thru some of the wiring on the compressor. He spliced the wires together and the system started up, I applaud him for not assuming that the board was faulty and just replacing the board. I would say that Mike did an A+ job troubleshooting to determine what the issue was. The only problem was the cost, and I suppose I should have asked more questions. I asked how much to come out and was told $99 to troubleshoot, but I never asked what other charges apply. Apparently the charge is $99 just to show up and troubleshoot the issue, then $220 per hour is added to that for Mike's time there. I felt $319 was a little steep, but perhaps that is the going rate. I want to emphasize that Mike did an excellent job of solving the issue."

FAQs for central a/c service or repair projects in Nashua, NH

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.
