When a system stops working, the first thing most people want is a straight answer about what is wrong and what it will take to fix it. Call us and you get that answer on the phone, before anything is scheduled. We talk through what the system is doing, scope the job from the description, and give you a price that covers what the visit involves. That is how every call starts, whether you are a homeowner dealing with a furnace that has gone quiet or a property manager trying to sort out a rooftop unit before the week gets complicated.
We handle heating and cooling repair, installation, and maintenance across Rockville and the surrounding communities. Furnaces, heat pumps, central air systems, boilers, ductless mini-splits, ductwork, thermostats, and indoor air quality equipment all fall within the scope of what we do. We cover the full range of residential and commercial work in this area, and every job starts the same way: clear communication from the first call to the final test.
Heating and cooling work gets explained in plain terms. The price you get is built from what the job actually involves, not from a standard rate that does not account for the conditions at your property.
What moves a quote is the fault itself, what has to be accessed to reach it, and whether a repair makes more sense than a replacement given the age and condition of the equipment. An evaporator coil that is accessible and clean to work around is a different job from one buried in a tight air handler with years of buildup on it. A heat pump nearing the end of its design life calls for a different conversation than a two-year-old unit with a failed capacitor.
When you call, we work through that on the phone. The price is confirmed before the visit is booked, and it covers what the visit includes. If the diagnostic turns up something that changes the scope, we explain it and confirm the new direction before any additional work goes ahead.

Rockville has a substantial share of older housing, and older homes carry their own set of conditions. Equipment installed in a crawlspace with limited clearance, air handlers mounted in tight attic spaces, or ductwork that was sized for a system that has since been replaced: all of these affect what a service call involves and how long it takes. We account for that when the job is scoped on the call, so the quote reflects the real situation rather than an idealized one.
Boilers and hydronic systems in older homes often have components that have not been serviced in years. A zone valve that has seized, an expansion tank that has lost its charge, or a circulator pump running at the edge of its capacity are the kinds of findings that a thorough visit turns up. Addressing them as part of the service rather than waiting for a failure is what keeps a heating season from becoming an emergency.
A system's age says a lot about which repair makes sense, and that conversation is worth having honestly. An air conditioner or furnace that has been running for a long time may be worth repairing if the fault is straightforward and the rest of the equipment is in reasonable condition. If the compressor is pulling high amperage, the heat exchanger has a crack, or the unit has needed refrigerant added more than once, the repair-versus-replacement question deserves a real answer rather than a patch that buys one more season.
We walk through both options when the situation calls for it. The goal is a decision that makes sense for the property, not one that generates a second call in eighteen months.
A no-heat call in the middle of a cold stretch, or an air conditioner that stops on a hot afternoon, is a different situation from a system that is underperforming. We take short-notice work, and emergency calls are answered every day from 8 AM to 10 PM. When you call, the person who answers knows the trade and can scope the job on the phone before anything is dispatched.
For tenants and businesses that cannot simply wait, we discuss the situation on the call and confirm what is available. The price is settled before the visit is sent, and the scope covers what was agreed. Nothing is added to the job without your approval.
For commercial properties where the building has to stay open, the same process applies. A retail space with a failed air handler or an office building with a boiler that has dropped pressure needs a repair path that accounts for the occupants, and we scope that on the call. We'll confirm the repair with you before it goes ahead. There is a fuller write-up on the HVAC services page.
A furnace that is running but producing less heat than it should, or one that has triggered a fault code related to the heat exchanger, needs a proper inspection before the season gets colder. A cracked heat exchanger is a safety issue as well as a performance one, because combustion gases can enter the air stream. The inspection involves the full exchanger surface, not just the visible sections, and the findings are explained before any repair or replacement decision is made.
Forced-air heating pulls moisture out of the air, and the result in winter is a home that feels colder than the thermostat says and air that is hard on woodwork, floors, and the people in the building. A whole-home humidifier works with the air handler to maintain a consistent moisture level across the heating season. On the other side, humid summers in this region mean that some homes benefit from a whole-home dehumidifier that takes the load off the air conditioner and keeps indoor air from feeling heavy even when the system is running.
Many of the older homes in Rockville and across Montgomery County heat with hot-water or steam systems. A boiler service visit covers pressure readings, zone valve function, circulator pump operation, and bleeding the distribution loop where needed. A radiator that stays cold while the rest of the house heats, or a boiler that loses pressure between cycles, points to a specific part of the system, and the diagnostic follows that rather than treating the whole system as a single unit.
For homes that still run on oil heat, the conversation about conversion to gas or to a heat pump is one we have regularly. The equipment side of a conversion, sizing the replacement and connecting it to the existing air distribution, is the work we scope and price on the call.
An air conditioner or heat pump that runs without cycling off, or a furnace that runs all day and still does not bring the space to setpoint, is worth diagnosing rather than assuming the equipment is simply undersized. A low refrigerant charge, a dirty evaporator coil, or an air handler running with a blocked return can all produce the same symptom. So can a duct system that is losing conditioned air before it reaches the rooms it is supposed to serve. Ductwork repair and sealing addresses the distribution side, and air handler and blower service addresses the equipment side. The diagnostic determines which one the situation actually calls for.
Fast diagnosis. Pricing set out up front. Comfort restored.
Uneven temperatures from room to room are one of the most common calls we take, and the cause is rarely the equipment itself. A condenser and compressor that are working correctly, paired with a duct system that has a collapsed section or a disconnected joint, will still leave certain rooms short of conditioned air. The same is true of a blower running at the wrong speed for the system it is attached to, or a damper that has closed and stuck.
Ductwork repair and sealing addresses leaks and disconnects in the distribution system. Where the ductwork is sound but the building has rooms that were added without extending the system properly, a ductless mini-split handles both heating and cooling for that space without requiring a duct run. Zoning systems and smart thermostat upgrades give more precise control over which parts of a building get conditioned and when.
Energy-efficiency upgrades often start with the distribution system rather than the equipment, because a well-functioning air conditioner pushing conditioned air into an unconditioned crawlspace is not going to deliver the efficiency its rating suggests. We look at the whole system rather than the unit in isolation.
We serve Rockville and the communities nearby, including Derwood, Redland, North Bethesda, Aspen Hill, and Washington Grove. Montgomery County residential and commercial customers are covered across the full range of heating and cooling work, from routine maintenance to full system replacement.
If you are in the area and want to confirm coverage before you call, the answer is on the phone. We're one phone call from getting your comfort right.
Older homes in Rockville and across Montgomery County run on a wider range of heating equipment than newer construction, including steam boilers, hot-water boilers with baseboard or cast-iron radiators, oil-fired furnaces, and heat pumps installed as part of earlier conversions. We work on all of them. If you are not sure what system you have, describe what you see when you call and we can identify it from the description.
Not always, but it depends on compatibility. An older thermostat may not communicate correctly with a new system, particularly if the new equipment uses variable-speed controls or communicating technology. We check compatibility as part of the installation scope and let you know if the existing control needs to go.
When a tenant or a landlord calls about a no-heat situation, the call is handled the same way as any emergency: the job is scoped on the phone, the price is confirmed before the visit is dispatched, and we discuss what is available given the schedule. The tenant does not need to diagnose the problem. Describing what the system is doing, or not doing, is enough to get the visit scoped and the price confirmed before anything is sent out.
Someone with access to the property and the equipment needs to be there. That can be the tenant, the landlord, or a property manager, as long as they can let the technician in and confirm what work is approved. For commercial or multi-unit properties, a building contact fills that role. We confirm the arrangement on the call when the visit is booked.
Call and give us the address. We confirm coverage on the call before anything is scheduled. The answer depends on where the property sits relative to the area we work in, and that is a faster conversation than guessing.
A diagnostic visit is how we establish what is wrong and what the repair or replacement would involve. The diagnostic is a visit with a cost, and the price for it is confirmed on the call before it is scheduled. The outcome of the diagnostic is what informs the repair or replacement recommendation.
It depends on what stage the work is at and what documentation exists for the job. We can assess where things stand on the call and confirm whether we can take it from there. If the work already done creates complications, we will explain what those are before any commitment is made.
The most useful thing a service visit does is tell you what you are actually working with. A system that is worth repairing is worth repairing well. One that is not is worth knowing about before another season goes by. We give you that answer once someone has actually looked at it, not before.
Call (240) 939-5495. We are available every day from 8 AM to 10 PM.
