"Decided to give MSD a call as I had another company over the house today to fix my AC and they were not able to repair it as they needed to order parts. Mehmet answered the phone and couldn't have been more professional/helpful. He spent 10 or so mins on the phone with me trying to understand the problem and give me advice. He unfortunately couldn't send some one out as he was super jammed with the current heat wave. I will not hesitate to call Mehmet again as he is a true professional and very knowledgeable."

"I'd become increasingly concerned about the company I was using for my AC and heating needs. When I knew we needed a lot of work doing, I decided to search for a new company that I could trust. We needed to get 4 new AC units installed. They were 17 years old and leaking, so we took the plunge and decided to replace them. I had a lot of questions around the systems in my house and what to install. During my phone conversations Donny was extremely helpful and patient. He answered all my questions and I believe that he gave me honest suggestions on the best solutions for my home and living situation. I found him to be honest, trustworthy and very knowledgeable. The install went smoothly, one of the units was tucked away in a tight closet in my daughters room, and they dealt with that easily. They installed 4 new controllers. They were tidy, and worked long hours to get the job done. In addition they spent time explaining the new systems to us and answering questions of ours that arose. We are really pleased with the new systems and controllers, we have peace of mind that we've installed good, reliable systems, and that we have a great company looking after our AC and heating needs. I also hired them to do annual service visits for our heating and AC. So far they have performed the winter maintenance visit, and identified a couple of things that needed addressing to prevent possible problems this winter. What they recommended made sense to us, and we thought they were valid and worthwhile repairs. As we trust this company, we decided to go ahead and get the work done. Chris D came to do the repair job. He was very friendly, helpful, hard working, and did a great job. He also took time to make sure we knew what was going on. I'm hugely relieved that I found this company. It's increasingly rare to find companies to help out in the home who are good at what they do, honest and trustworthy. I highly recommend them. BTW I'm also impressed with their office support staff. They are super friendly and helpful, calling back when they say they will. Booking appointments is super easy with this company."

"Affordable HVAC repair service. You can actually ask them to do little extras at no additional cost. After I called them for emergency repair of our AC unit, they offered a complementary cleaning for the unit. Amazing customer appreciation. Totally recommended!"

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"I recently had the pleasure of working with Schede Plumbing and Heating, and they were a lifesaver when it came to fixing my central air issues. As a new homeowner, I’ve been faced with different challenges every day, but knowing who you can trust and ask for help makes all the difference. I was fortunate to be introduced to Schede Plumbing and Heating, and they exceeded my expectations. From the moment I called, they were quick to respond and provided a thorough analysis of the problem. They walked me through the options and suggested the most practical and affordable solution. I was serviced by two highly professional, polite, and skilled technicians, Paul and Randy, who were truly exceptional. Paul and Randy were efficient, trustworthy, and very customer-focused. They assured me that they wouldn’t leave until my issue was fixed and took the time to ensure no other issues were lurking. Their dedication to solving my problem and their attention to detail were impressive. I cannot recommend Schede Plumbing and Heating enough. They are a reliable and professional team who genuinely care about their customers and their work. Thank you, Paul and Randy, for your excellent service!"

FAQs for central a/c service or repair projects in Norwalk, CT

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.
