Nero's Heating & Air repairs, maintains, and replaces heat pumps, furnaces, air conditioners, ductless mini-splits, and water heaters throughout Germantown. Our technicians handle everything from complete system breakdowns to equipment that still runs but no longer heats or cools the home properly.
That work takes us across Germantown every week, from Churchill, Waters Landing, and Gunners Lake to Kingsview, Father Hurley Boulevard, and the streets around Liberty Mill Road. Wherever you are in town, we can come out, find the problem, and get you a clear answer on what the system needs.
We work on furnaces, boilers, and radiators throughout Germantown. Calls range from no heat at all to systems that cut out early, struggle to keep up, or leave parts of the house colder than others. We test what is happening first, then explain whether the system needs repair, service, or replacement.
Some air conditioners stop completely. Others keep running but never quite bring the house down to the thermostat setting. Our air conditioning technicians handle both, along with routine maintenance, system replacement, and emergency cooling repairs when the problem cannot wait.
Heat pump repair, installation, and maintenance are steady work here. One outdoor unit carries both seasons, so a fault shows up as weak heat in January or weak cooling in July. Ductless mini-split work is handled by the same technicians, including the wall heads and the refrigerant line run.
We repair and replace both tank and tankless water heaters. Most calls begin with hot water running out too quickly, slow recovery, or water appearing around the tank. If the tank itself is leaking, we will tell you when replacement makes more sense than repair.
Air that feels damp in August and dry enough to crack lips in February is a humidity problem rather than an HVAC one. Whole-home humidifiers and dehumidifiers are what our indoor air quality team installs to improve indoor air quality, alongside duct cleaning for systems that have carried the same dust for years.

Germantown HVAC Work Can Involve the County and Your Association
Replacing an HVAC system in Germantown requires a mechanical permit from Montgomery County. The inspection path then depends on the equipment. Gas-fired systems can also involve WSSC Water, while an all-electric heat pump stays with the county.
We handle the permit, submit the required equipment information and carry the job through inspection.
If you live in an HOA or condo community, there may be a second approval to think about. Outdoor units, line-set routing or visible exterior changes can fall under association rules, so we bring that up before the installation date is locked in.
Paying for a Heat Pump or Furnace Replacement in Germantown
Rebates
Pepco serves Germantown and offers qualifying HVAC incentives through Maryland energy-efficiency programs. Depending on the current program, eligible equipment can include heat pumps, ductless mini-splits and central air conditioners.
What matters is the system you are choosing and whether it meets the current requirements. We check that during the estimate, so you know whether a rebate may apply before anything is ordered.

Financing
We offer financing for HVAC replacement if you would rather spread the cost over time. You still see the full written project price first, then you can compare it with the available payment options before deciding how you want to pay.
Typically, it goes on the rear yard or a side strip. Attached houses are 41 percent of the stock here, the largest single category, so clearance and the line run are set by the lot.
Not automatically. Nearly six in ten homes here went up in the 1980s and 1990s, so the ducts are often original, and whether they suit new equipment gets checked rather than assumed.
Largely when they were built. Census figures put electricity at 56 percent of occupied homes against 40 percent on utility gas, so a heat pump is the normal system here.
Usually, the landlord or a managing agent. Montgomery County requires a rental housing license and sets a minimum of 68 degrees, so heat is an obligation with a number attached.
Low outdoor temperature, or a fault. Backup resistance strips draw far more power than the compressor, so a thermostat calling for them in mild conditions is worth investigating.
