Gaithersburg has plenty of townhouses, condos and apartments, so HVAC equipment is often tucked into tighter spaces than it would be in a detached home. Nero's Heating & Air works with furnaces, air conditioners, heat pumps, ductless mini-splits, boilers and both tank and tankless water heaters throughout the city.
That includes the townhouse communities off Quince Orchard Road, newer homes in Kentlands and the apartment blocks along Montgomery Village Avenue. We work across that mix of buildings and equipment every week, so the layout of the property is part of the job from the start.
Heating repair, maintenance, and replacement are all handled by our heating technicians, from a furnace that lights and cuts out again to a boiler that heats the radiators at one end of the house and not the other. Emergency furnace and boiler repair is part of the same work.
Is the system running and the rooms still not cooling? Our AC technicians repair, maintain, and replace cooling systems, working the outdoor condenser, the indoor coil, and the blower that moves the air, and emergency air conditioning repair covers a house that has lost cooling entirely.
Heat pump repair, installation, and maintenance go to the same technicians, down to the reversing valve, the outdoor coil, and the backup heat that carries the coldest nights. Ductless mini-splits sit with them too, including the wall heads and the line set feeding them.
Hot water that gives out partway through a shower, or rust around the base of the tank, is where a water heater call usually starts. Our technicians work on storage tanks and tankless systems alike, repairing what can be repaired, though a tank that has started leaking goes to replacement.
Does one room never feel like the rest of the house? Damp that settles in a lower level, and air dry enough to raise static off a carpet, are humidity problems rather than temperature ones, so our indoor air quality specialists install whole-home humidifiers and dehumidifiers and clean ductwork.
Replacing an installed HVAC system in Gaithersburg requires a residential mechanical permit from the city, not Montgomery County. Before issuing it, Gaithersburg requires the contractor to show a current Maryland heating, ventilation, air conditioning, and refrigeration license.
We handle that process as part of the installation. Our team files the permit, submits the equipment and license information the city requires, and carries the job through final inspection. The permit fee appears once on your final invoice.
Historic districts are the main exception to the normal timeline. Exterior work there may also need review by the City of Gaithersburg Historic District Commission, which works on a meeting schedule rather than the regular permit timeline. If that applies to your property, it needs to be planned for before the installation date is set.
Which rebate route is open here is decided by the building rather than by the equipment. The residential side of EmPOWER Maryland is run locally by Potomac Electric Power Company (Pepco), whose whole-home route, Home Performance with ENERGY STAR, is written for a single-family home, a town home, a row home, or a dwelling of one to four units. A participating contractor has to perform the assessment and the work.
We go over what currently applies when our team comes out for the estimate, so you know how it affects what you actually pay.

A new HVAC system is not always an expense you have months to plan for. We offer financing options that can spread the cost over monthly payments instead of requiring the full amount upfront.
You can review the financing terms alongside your written estimate, so you see both the monthly payment and the full project price before deciding how you want to move forward.

Wherever the lot allows. Census figures put 29 percent of homes here in attached buildings, so the pad and the line run get measured before anything is ordered.
Age, mostly. Fifty-seven percent of the housing here went up between 1970 and 1999, so whole streets reach the end of a second or third system at much the same time.
Gas, but narrowly. Census figures show 53 percent of occupied homes heating with utility gas and 43 percent with electricity, which here usually means a heat pump with electric backup.
It can. Gaithersburg takes part in the National Flood Insurance Program, and the Federal Emergency Management Agency revises its maps, so the zone a property sits in now is worth checking.
Yes. Our technicians work on systems regardless of who installed them. Parts availability is the usual limit on an older unit rather than the make, and we say so before starting.
Whether the system has just quit, has been making a noise you keep meaning to mention, or is simply something you are planning ahead for, tell us what you have noticed. Our team can go through what is worth doing and what it would involve.
