We Diagnose It Before We Quote It.
Serving Washington, DC, Prince George’s County, Montgomery County & Northern Virginia, including Upper Marlboro, Hyattsville, District Heights and Silver Spring.
Nero’s Heating & Air is a Cheverly-based HVAC company working across Washington DC, Prince George’s and Montgomery Counties, Southern Maryland and Northern Virginia. Since 2019 we have repaired, installed and maintained air conditioning, heating, ductless systems and water heaters in homes around the DMV, most of them older than the equipment sitting inside them. We find out what is actually wrong before we quote the work, and we will tell you when a repair beats a replacement.
About Us
We treat every home like it’s our own and every customer like a neighbor. Honest work and real relationships are what Nero’s Heating & Air is built on.
Julian Jones Founder
Most of the AC calls we take in July come down to four things: a blocked drain pan, a failed capacitor, a condensate pump that has stopped clearing, or a system that has simply run past its useful life. The first three are repairs and we carry the parts for them. The fourth is a replacement conversation, and we will only start it once we have looked at the system and can show you why it is worth replacing.
Cooling
A furnace that will not light usually comes down to a flame sensor, an igniter, or a safety switch that has shut the system off on purpose. A furnace that lights and then shuts down within a minute is telling you something different, and that one is worth taking seriously. We test the gas pressure, the heat exchanger and the venting on every heating call, because those are the checks that decide whether a system is safe to keep running.
Heating
Homes across Prince George’s County and DC swing between two very different indoor-air problems: dry, static-filled air in winter and heavy, sticky air in summer, with dust building up in the ductwork all year. We help you keep every room comfortable and the air feeling fresh through both seasons.
Indoor Air Quality
A water heater rarely fails without warning first. Rust in the hot water, a longer wait for it to arrive, or a pan that keeps collecting water are all signs the tank may be nearing the end. We service both tank and tankless systems, and if the unit is still relatively young, a repair often makes more sense than replacing it.
Water HeatersEvery visit starts with finding out what is actually wrong, not with a number. If the system can be repaired, we recommend it; if it cannot, we explain why. You end up deciding between a repair and a replacement with the same information we have, rather than taking a figure on trust.
Call and explain the problem in English or Filipino. Nobody will ask you to slow down, repeat yourself, or put someone else on the phone to translate. We are hiring to add more languages, because the clearer you can be, the faster we fix it.
Rowhouses and mid-century homes across Cheverly, Hyattsville, and DC were not built around their ductwork, so the runs are tight, and the equipment spaces are awkward. A like-for-like swap often will not fit. Spotting that before anything is ordered is the difference between a system that works and one you end up paying to have corrected later.
Nero’s Heating & Air holds Maryland HVAC/R license #47671. Our team includes a Master HVAC license holder and EPA-certified technicians, and we carry general liability and workers’ compensation coverage. You get a qualified, insured company working on your home.
About half a year after a job, we message to ask how the system is running. Six months is roughly when a sizing or airflow mistake starts to show, so asking then means we catch it while it is still ours to put right, instead of you living with it through another summer.
Our summer service calls come down to the same handful of failures: drain pans, capacitors, condensate pumps and blocked drain lines. Seeing them that often means we recognize them fast and keep the parts on the truck, so the common ones get fixed on the first visit rather than becoming a second appointment three days later.
After hours, your call is answered by an experienced member of our team, not an answering service. We ask what the system is doing and tell you straight away whether it needs a technician tonight or can safely wait until morning. You decide before anyone drives out.
Sundays, after-hours and rooftop calls carry a $169 emergency fee, and that one is not waived. We will say so on the phone before we come out, so the cost of the visit is settled before anyone is in a truck.
Some failures will sit safely until daylight without getting worse. When it can safely wait, we book you first thing at the standard rate. You get the same technician and the same repair, without the emergency fee.

See service area“Needed an emergency AC fix on a brutally hot Saturday. He arrived within 30 minutes of me calling and before the scheduled time, quickly diagnosed and fixed the problem. He was very candid and professional and gave honest, great advice. It wasn’t cheap, but for a Saturday night summer heat emergency it was totally worth it.”

Twice a year, spring and fall. The DMV works a system hard at both ends, and humid summers leave condensate lines prone to algae growth and blockages that cost less to prevent.
Most replacements are finished inside a single business day. Where duct alterations are needed the work can stretch across two. Expect two to four weeks between estimate and installation.
Plan to be there for the full day, even where we estimate half. The walkthrough and the thermostat setup both happen at the end and need you there to sign off.
Clear a path to the indoor and outdoor units, put pets somewhere else, and note down when the problem started. That last one shortens the diagnosis more than people expect.
Yes, we service any make regardless of who installed it. Have the model number ready if you can find it, though we can read it off the unit ourselves.
