Whether a heating or cooling system can be repaired or needs to come out entirely is the question most callers lead with, and it is the right one to ask first. The answer depends on what the fault actually is, what the repair would cost against the age and condition of the equipment, and what a replacement would look like for the space. We scope that conversation on the call, and we give you a straight answer before anything is scheduled.
We handle heating and cooling repair, installation, replacement, and seasonal maintenance for homes and businesses across Nashua and Hillsborough County.

A second opinion on a heating or cooling problem is a reasonable thing to ask for, and we take those calls. If a previous repair did not hold, or if a diagnosis came back with a recommended fix that did not match what the system is actually doing, we start from the beginning. Refrigerant, airflow, and controls all get checked before a verdict, because the symptom and the cause are not always pointing at the same component.
Taking over a job partway through is something we handle regularly. If work was started and left incomplete, or if a repair was made and the system still is not performing, call and describe what happened. We will assess what is there and tell you what the path forward looks like.
A surprising number of calls turn out to be thermostat issues rather than equipment failures. Before calling, check that the thermostat is set to the correct mode, that the temperature setting is above or below room temperature in the direction you need, and that it is actually powered. A thermostat that lost its connection to the system after a power fluctuation can make a fully functional unit look like it has failed. If the thermostat is blank or unresponsive, check the batteries and the circuit that feeds it before assuming the equipment is the problem.
A clogged filter restricts airflow enough to cause the system to shut down on a safety limit, and it is the kind of fault that looks like a mechanical failure until you pull the filter out. Check it, and if it is visibly blocked, replace it before calling. Also check that the power switch at the air handler has not been bumped off. That switch is usually on the wall near the unit and looks like a standard light switch. It gets turned off during other work in the space and sometimes stays that way.
If the indoor unit is running but the outdoor condenser is not, check that the disconnect box near the outdoor unit is fully closed and that nothing has tripped the breaker feeding it. The breaker itself is the electrician's side of the work, but confirming it has not tripped takes thirty seconds and can save a service call. If the outdoor unit is running but the system is not cooling, that is a different problem and worth a call.
We take calls every day from 7:00 AM to 10:00 PM, including weekends. For properties with no heat or no cooling at all, those calls are handled within those hours and treated as the priority they are. A home in the middle of a cold stretch with no heating, or a building with no cooling during a humid stretch in July, is not a situation to wait on.
Call (978) 992-9593 and describe what the system is doing, and we will work through what is needed.
For rental properties, we work with landlords and property managers who need a unit back in service quickly and a clear account of what was done. For commercial spaces that need to stay open, scheduling around operating hours is part of the conversation when the job is scoped. The scope and the price are settled on the call before anything is booked. Heating and cooling work gets explained in plain terms, so whoever is responsible for the property knows what the job involves before it starts.
Much of the older housing stock in this part of New Hampshire runs on hot-water baseboard or cast-iron radiator systems. These setups are durable, but they develop specific faults over time: circulator pumps that wear out, zone valves that stick, pressure that drifts, and sections of the distribution loop that go cold while others run fine. We work through the full hydronic system, not just the boiler itself, and we tell you what we find before any repair is quoted.
The Northeast holds the majority of the country's oil-heated homes, and a significant share of properties in this area still run on oil. When oil equipment reaches the end of its service life, conversion to a gas furnace or an air-source heat pump is often the practical next step. We handle the equipment side of that transition: removing the old oil-fired unit, installing the replacement heating system, and confirming it is operating correctly. The gas-line run to the equipment is plumbing scope, but the heating unit and its final connection are what we do.
Many homes in Nashua were built without central ductwork, and additions or finished spaces often have no duct access at all. A ductless mini-split handles both heating and cooling for those spaces without opening walls or ceilings. We install single-zone and multi-zone systems, position indoor air handlers for the coverage the space needs, and set up the controls before sign-off. Mini-splits also work well as supplemental heating and cooling in spaces where extending existing ductwork is not practical.
Humidity control matters in both directions across a New England year. A whole-home humidifier installed on the air handler addresses the dry air that comes with running forced-air heating through a cold winter. A dehumidifier addresses the humidity that older, less-tight buildings hold through the summer. Both are installed as part of the existing HVAC system, and both make a measurable difference to how comfortable a space feels at a given temperature.
An AC that does nothing when the thermostat calls for cooling is usually pointing at one of a few places: a failed capacitor, a tripped safety, a control-board fault, or a refrigerant issue that caused the system to shut itself down. The diagnostic covers the full sequence from the thermostat signal through the air handler and out to the condenser before any part is quoted. We do not recommend a replacement until the fault is confirmed and the repair cost is weighed against the age and condition of the equipment.
A system that runs without reaching the set temperature is either undersized for the load, losing refrigerant, restricted by a dirty coil or blocked airflow, or working against ductwork that is leaking conditioned air before it reaches the rooms it is meant to serve. The visit covers all of those possibilities. A system that has been running fine for years and suddenly cannot keep up is more likely a refrigerant or coil issue than a sizing problem, and that distinction changes the repair path.
A refrigerant leak does not always announce itself. Low charge shows up gradually as reduced cooling capacity, longer run times, and eventually ice forming on the evaporator coil. We locate the leak, confirm the charge, and repair it before recharging the system. Recharging without finding the leak is a short-term fix that leaves the same problem in place.
A compressor that is failing draws higher current, runs hot, or trips the system on a safety limit before it stops working entirely. A condenser with a failed fan motor or a coil that is heavily fouled will reduce the system's ability to reject heat, which pushes the compressor harder and shortens its life. We assess both before recommending a component repair or a full outdoor-unit replacement, because the two decisions are connected.
The price depends on what the fault turns out to be, what has to be accessed to reach it, and whether a repair or a replacement is the better answer for the equipment's age and condition. A refrigerant recharge is a different call from a compressor replacement or a full system installation, and the quote reflects the actual scope of the job.
When you call, the job gets scoped on the phone and you get a rate before anything is booked. If the diagnostic on-site turns up something different from what the call described, the new scope is explained and priced before the work proceeds. You are told what the visit covers, and you are told what any repair costs, before anyone starts spending.

Short cycling, where the system starts and stops more frequently than normal, is worth calling about. It can be caused by an oversized system, a refrigerant problem, a dirty filter restricting airflow, or a control fault. Left unaddressed, it puts repeated stress on the compressor and other components.

A significant share of homes in this part of New Hampshire run on hydronic heating systems, including hot-water baseboard and cast-iron radiators, often paired with oil-fired boilers. Many properties were built before central air conditioning was standard, which is why ductless mini-splits are a common upgrade here. If you are not sure what type of system you have, describe what you see when you call and we will work from there.
