Overcoming The Suburban Swamp
Middletown is expanding faster than a rocket at liftoff, and with that growth comes a unique architectural challenge. Many of the newer builds in the 19709 area feature expansive floor plans that standard HVAC systems struggle to regulate. This leads to the "suburban swamp" effect—where your upstairs feels like a sauna while your basement is a walk-in freezer.
Moon Air is the specialized HVAC contractor in Middletown, DE, that provides the engineering necessary to balance your home’s "ecosystem."

Job Locations and Reviews
Upon arrival, I found the condensate overflowing on the floor in the bedroom. After removing the front cover, I discovered that the condensate drain was pitched upwards, causing it to drain back into the pan. To correct this, I had to cut out the wood and enlarge the hole to ensure proper drainage. I then tested the drain and ran the system until it produced condensation, confirming that all operations were running normally. To prevent future buildup, I poured a cup of clear vinegar into the condensate pan. The work was completed under warranty, with no payment required.
I addressed the customer's concern about their Daikin Mini split not cooling effectively on extremely hot days. I cleaned the air filters and the outdoor coil, and assessed the indoor heat exchangers' placement. I explained the benefits of our regular service membership plans to maintain the system's performance. The customer showed interest but decided not to commit immediately.
I conducted a thorough maintenance check on the gas furnace's AC components, achieving a Delta T of 21 degrees. The air filter was replaced and dated. Voltages and amps were verified to be within acceptable limits. The air handler's interior and indoor coil drain were cleaned. The blower passed the tissue test. I also cleaned the outdoor unit, ensuring it ran in cooling mode with voltages and amps within range. A drain pan treatment for the indoor coil drain pan is recommended.
club renewal
I successfully managed the renewal process for two exclusive gold club memberships. This involved verifying and updating the membership details, ensuring all personal information was current and accurate. I navigated the membership portal to complete the renewal forms, handled any necessary payments, and confirmed the renewal status. Additionally, I reviewed the benefits associated with the gold club membership to ensure the members were fully aware of their entitlements. The renewals were processed promptly, maintaining the members' premium status without any interruptions.
Upon arrival, I identified that the air conditioning system was not functioning. Upon inspection, I discovered that the exhaust removal system was faulty. The variable speed exhaust removal system (EXS) was found to be the root cause of the issue, causing the unit to trip the high pressure switch. To prevent further damage, I powered down the AC system and informed the customer that the system would remain inactive until the faulty part was replaced. After obtaining the necessary replacement part, I returned and installed it. Following the installation, I thoroughly checked all operations to ensure everything was functioning correctly. The air conditioning system is now operating normally, and all systems are running as expected. This work is covered under warranty, as indicated by the WO-TNFR667434 warranty.
I inspected the evaporator and confirmed that the level was satisfactory. The drain pitch was also checked and found to be appropriate. The outdoor unit was examined for wiring and piping integrity, both of which appeared to be in good condition. The charge unit was found to be low on refrigerant, so I added 2 ounces of R-32. The subcooling improved from 5 to 8, indicating a successful adjustment.


Job WO-TNFR662649 involved a comprehensive rejuvenation of two AC systems. The basement unit was thoroughly cleaned and tested, showing no operational concerns and operating efficiently. The upstairs unit, however, required attention. The air circulation motor was showing signs of failure, prompting a recommendation for replacement. A silver repair option was selected, and the office will coordinate the return visit once the necessary parts arrive. Upon returning, the main exhaust removal system's motor was replaced, the exhaust blade was renovated, multiple secondary electronics were replaced, and wiring issues and connections were corrected. Post-repair testing confirmed the system's operational status and improved efficiency, verified by temperature checks at the vents.

I scheduled an estimate visit with Steve Podesta after meeting him at the Middletown Peach Festival, where I asked him about the mini-split. The visit took place on 6 Sept, 2023 and was great. Steve analyzed the room where I'd place the mini-split, shared some options about its possible placement in the room and outside, carefully explaining how the coolent and drainage pipes would be placed/arranged coming from the room to the outside pump. He worked up a proposal with my options and provided the product literature for the units proposed. I have all I need to make a decision. I'm very satisfied with the visit. Thanks!
