Welcome to Comfort Air, proudly servicing Baltimore and the surrounding areas. Our goal is to complete your project to perfection. We look forward to building long lasting relationships with the customers that we serve. We look forward to serving you. Call us today! You will not be disappointed.

"I have a dual zone system and the air handler/heat pump unit on the 2nd floor was blowing hot air. I immediately looked up HVAC service in the Bel Air area and came upon Comfort Air. I initially chose this company based on the good reviews. I was told by the technician that based on the age of the unit and problem it was more cost effective to replace the unit instead of making a temporary fix. I agreed and after entertaining some estimates I chose Comfort Air. We negotiated a very reasonable price along with a quality unit. The installers were very professional and completed the work in about 4 hours. I would highly recommend Comfort Air for any Heat and Air Conditioning needs."

"In a genuine crisis when my boiler failed, I was turned away by six other companies. At Your Service was my hero, answering immediately and scheduling Jason and Ryan, who were nothing short of incredible. They provided a swift, honest diagnosis and took the time to transparently explain why a full system replacement was the safest and most efficient long-term solution—no pressure, just facts. Their communication was outstanding; they kept me informed and comfortable with every single step, ensuring there were no surprises. When our home grew cold during the install, their compassion truly shone as they proactively checked on my family's comfort. They also presented flexible, affordable options that perfectly respected my tight budget, delivering a high-quality, efficient system with impressive speed. The work area was left spotless. I cannot recommend Jason, Ryan, and At Your Service enough. They have set the gold standard for honest, skilled, and genuinely compassionate service."

"HORRIBLE CONTRACTORS!!! I have had contractors before and experienced some issues but this Anthony guy is very unprofessional and he is an absolutely nightmare! Not a single item was completed from the contract he and I agreed on and he took 60% of the contract amount and he stopped working the property. I had a property with some cosmetic work stuff and repairs which shouldn’t be that complicated. After he toured the property and gave me estimated time frame for 2 weeks. I know normally how it is not done with contractors so I asked him a few more times and confirmed if he could really finish it in two weeks. He was confident and said two weeks for no problem. After it has been almost 4 weeks, not even a quarter of work has been done and I noticed he didn’t even show up. He has so many excuses and complaints every single time when I contacted him. It felt like he was working for free which was not true. We agreed on 3 installment payments, 1st installment, before the job start about 30% of the total price, and 2nd one, 1/3 of the total price, and the last one at the completion of the job. After 2 weeks of work and not much of work has been done, he already requested for the 2nd installment. I asked him, the work has not been done 2/3 of the job, more over not even half way done. Anyway, he got upset and he wouldn’t continue the job if I didn’t pay. So I paid and then BOOM! He didn’t show up at work and when I asked him, his answer was it is too cold to work at the property. He made excuses and excuses and he said he will only come back if the heater is fixed. I did and texted him and called him. NO RESPONSE. Besides, his quality of work is horrible. He and his crew painted all over, light fixtures, light bulbs, floors, even bathtub. What kind of painter paint over the tub?! They simply didn’t even covered the parts not supposed to paint but they were so lazy and sloppy worker. They installed the brand new room doors, two out of three, didn’t even close properly and didn’t even use the shim. Installing the door is one of the basic carpentry job and he can’t even do that! I asked for the breakdown of the work and cost and no answer. When I confronted him for a few stuff, he just blah blah blah and repeating himself by making endless nonsense and not doing the job at all. Even if he does a job, not a good quality one."

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