HVAC Services in Hyattsville, MD

Every service on this page comes back to one idea: the work is only as good as the measurement behind it. A furnace sized by rule of thumb, an air conditioner matched to the old tonnage, a repair quoted from a glance instead of a meter — those are how homes in Prince George’s County end up with equipment that runs but never quite works. We organize our services into six areas below. Whether you need a single repair or a whole-home system, the starting point is the same: readings first, recommendations second.

Cooling

Air conditioning and heat pump cooling built for the reality of a Zone 4A summer, where a 76°F design wet bulb means humidity is half the battle. We install, repair, and maintain central air, and we size every replacement by Manual J so the system actually dehumidifies instead of just hitting a number on the thermostat.

Heating

Furnaces, heat pumps, and boilers for a climate whose 20°F winter design temperature makes modern heat pumps and dual-fuel systems genuinely practical. On every gas job, combustion is analyzed and venting is verified — including the orphaned-water-heater trap that so many furnace swaps miss.

Indoor Air Quality

The August latent load that leaves so many homes cold-but-clammy is an air-quality problem as much as a comfort one. We handle whole-home dehumidification, MERV 13 filtration verified against static pressure, UV-C coil treatment, duct cleaning and sealing, and ASHRAE 62.2 ventilation for tight newer homes.

Maintenance

Regular service is the single biggest factor in whether a system reaches the top of its lifespan or fails early, and documented maintenance is required to keep most manufacturer warranties valid. We offer tune-ups, inspections, emergency repair, and maintenance plans that create the service record your warranty depends on.

Installation & System Upgrades

Full-system replacements, ductless retrofits for homes with no duct path, zoning for the second-floor-cooling problem, and smart-thermostat and air-handler work. Every installation is sized by Manual J, selected by Manual S, permitted, and commissioned with the readings on your invoice.

Commercial HVAC

Light-commercial service for retail along the Route 1 corridor, small offices near Hyattsville Crossing, and mixed-use property along Route 450 in Bladensburg — rooftop units, preventative maintenance, and service contracts that keep a business comfortable and code-compliant.

Frequently Asked Questions

What HVAC services does Swellfort offer?
We provide a full range of residential and light-commercial HVAC services across Hyattsville and Prince George’s County: air conditioning and heat pump installation, repair, and maintenance; furnace and boiler service; indoor air quality solutions including whole-home dehumidification and filtration; system replacements and ductless retrofits; zoning and smart controls; and commercial rooftop and service-contract work. Every service starts with measurement — a load calculation for installations, and diagnostic readings for repairs.
Do you service systems you didn’t install?
Yes. A large share of our work is service and repair on equipment installed by others, across all major brands. We diagnose your system on its own terms by reading fault codes, metering components, and checking refrigerant charge and combustion, regardless of who installed it or how long ago. You are never stuck because the original company is gone or you would rather work with someone new.
Which areas do you serve?
We serve Hyattsville, Chillum, Langley Park, Adelphi, Mount Rainier, and Riverdale Park, along with the surrounding Prince George’s County communities, from our office in the 20783 corridor. Because that office sits between Chillum and Langley Park, response times to the closest neighborhoods are typically the fastest in our service area.
Do you handle permits for the work you do?
Yes, on every installation. Mechanical permits are pulled through the Prince George’s County Department of Permitting, Inspections and Enforcement, and gas work is performed under WSSC Water gasfitter licensure. We schedule the inspection and the permit number appears on your invoice. This protects both the safety and the resale value of your home, since unpermitted work frequently causes problems during a sale.
How do I know which service I need?
You often don’t need to know — that is our job to determine. If your system is not working, we run a diagnostic; if you are considering a replacement, we run a load calculation and lay out the options. The same symptom can have several different causes at very different prices, so rather than guessing from a description over the phone, we measure and then tell you exactly what the situation calls for. Call (227) 249-1654 and we will point you to the right starting place.

Get Started — Hyattsville, MD

Whatever the problem — a system down, a room that never gets comfortable, or a replacement you have been putting off — the first step is a measurement. Call and we will send a technician who diagnoses before quoting.
