"Edmond responded right away and listened to my explanation of the issue over the phone. It was Friday afternoon and we both agreed the issue was non-urgent so we scheduled an early Monday morning visit. He showed up at 8a sharp as we agreed and he did a thorough check of our AC system. Edmond is very knowledgeable and he explained everything thoroughly. He gave me a couple of suggestions. I’m pretty handy so I’ll try to tackle it myself. He said to just call him if I get stuck and he could either come back out or coach me over the phone. Pricing is reasonable and quality of service is top-notch. I’ll keep them on speed dial and I highly recommend Hecomo for HVAC service!"

"I can’t say enough excellent things about Lance, the service technician who came out! We just purchased our first home so imagine our surprise when barely a month in the large grand chandelier fell from the ceiling in the early morning. I was going to replace it myself but remembered our home inspection pointed out some instances of aluminum wiring in the house so I thought I should have an electrician confirm the outlet was properly done before I go mucking around in the ceiling. Although it cost me an emergency dispatch fee, they had someone in my house first thing the very next morning. Lance was prompt and just so amazing - very kind and careful with keeping our house clean, taking care of the floors and finishings and really went above and beyond to help a very frazzled young family try figure out the mess they just purchased. While he was at our house we opted to have him also see if he could remove two outlets in the dining room from a dimmer switch so they can be always on. He explained the pricing up front and I knew what the job would cost as a final number before he began any work. For the first job, I was very impressed with how thorough and complete he was in taking care of not just the replacement chandelier, but even with safely disposing of the now broken old chandelier for us! He even offered to help move some boxes for the Salvation Army pick-up we had scheduled - I was just blown away by how kind and helpful he was! For the second job, I was so very pleased that he took the time to really figure out what was wrong. He ended up spending almost three hours discovering several issues - including things like faulty attempts at mitigating aluminum wire connection points in several outlets that we received confirmation prior to settling on the home had been fixed. He was able to come up with creative solutions to safely leverage what was already available to solve our problem and the best part is he really took the time to not only do it right, but to explain everything as he went and really helped me learn more about my house and how I can discover and resolve similar problems in the future. Being someone who is always trying to learn I really appreciated his willingness to answer my questions and share his depth of knowledge and experience! In the end, even though the job was a lot longer than either of us thought it would be, and even though the original cause for the emergency dispatch was already resolved, Lance made sure he stayed until we had a solution in place and we still only paid the initial quoted price! Yes, the price did seem a bit high compared to what I’ve seen on other provider’s quoted rates. However, the work really is just that good - absolutely worth it AND charging by the job instead of the hour takes all of the guessing out of how much you will need to pay, not to mention covers situations like this where the job ended up taking quite a bit longer than originally anticipated. We couldn’t be happier. We were so pleased with the service that we also signed up for their annual service plan to avoid emergency dispatch fees in the future and to get their annual safety inspection. There’s a lot of uncertainty associated with buying our first home, but at least we now know who we will call for all of our electrical needs!"

"JDL called within 30 min of placing my request and set up a visit. They evaluated my AC unit and agreed to repair, despite its age (more than 20 years old!). The cost was a fraction of a new unit. Their lead service tech, Isak, was great - knowledgeable, efficient and responsive to my questions. I was very impressed and will have them return for maintenance and service in the future."

"This is an excellent company. We have used them for year to service our heating and air conditioning units. It became necessary to think about replacing the units. We have two. Decided to replace both at the same time. They came out on a Monday and gave us an estimate and came out on Thursday and Friday to do the work. They totally cleaned up after themselves and made sure everything was working properly. Then they called a few days later to see that everything was working well. I highly recommend this company. All the technicians are polite and competent. The office staff is nice beyond belief. If you need any heating/AC work done, this is the company to do it."

"Same day AC repair! I called at 930 am and the tech fixed the AC by 2 pm. Amazing service. I bought the annual service policy for HVAC since Horizon was so prompt, professional, and knowledgeable!"

"THIS COMPANY EMPLOYS EXTREMELY TRUSTWORTHY EMPLOYEES THAT ARE A PLEASURE TO HAVE IN YOUR HOME. THE CARPENTER WE HIRED AT THE SAME TIME WAS SO IMPRESSED WITH THEIR WORK AND KNOWLEDGE, THAT HE HAS USED HIM ON OTHER JOBS HE HAS BEEN HIRED TO DO. THEY ALWAYS CLEANED UP AFTER THEIR WORK, THEY WERE COURTEOUS AND RESPECTFUL OF OUR HOME AND FAMILY, AND WERE VERY PUNCTUAL. SINCE THEY HAVE INSTALLED OUR SYSTEM, WE HAVE NOT HAD PROBLEMS OTHER THAT 'USER PROBLEMS' (I.E., NOT CHANGING FILTERS FREQUENTLY ENOUGH). HOWEVER, WHEN WE DO CREATE OUR OWN PROBLEMS, THEY HAVE RESPONDED VERY QUICKLY TO OUR NEEDS AND THEIR PRICES ARE VERY REASONABLE. I WOULD RECOMMEND THEM TO ANY FRIEND OR NEIGHBOR."

FAQs for central a/c service or repair projects in Glenwood, MD

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.
