Equipment rarely fails without warning. A furnace that hesitates before firing, a central air system that runs longer than it used to before the house cools down, a thermostat that seems to lose the plot on the coldest days: these are the signals worth acting on before the system stops altogether. Catching them early means a diagnostic call and a repair. Ignoring them often means an emergency call on a night when every HVAC company in the area is already busy.
We cover heating and cooling repair, installation, maintenance, and emergency service for homes and businesses across Somerville.
If you manage a multi-unit building, own a small commercial space, or are dealing with an older property that has never had its HVAC systems properly assessed, call (978) 992-9593 and we will scope the job before anything is scheduled.
Some calls come in because a previous repair did not fix the problem. The system ran for a few weeks, the same symptom returned, and now the property is back to square one. We take those calls. The first step is a fresh diagnostic, not an assumption that the original diagnosis was right. A repair that does not hold usually means something upstream of the replaced part was missed, and finding it requires going back through refrigerant charge, airflow, and controls rather than repeating what was already done.
If somebody has told you the system needs a full replacement and you are not certain that is right, a second opinion is worth having before committing to that cost. We assess the equipment, explain what we find, and give you a straight answer about whether a repair makes sense or whether replacement is genuinely the better call. Heating and cooling work gets explained in plain terms.
A system that runs without cycling off, or that cycles off and on every few minutes without reaching the set temperature, is not just an annoyance. It is usually a sign of a refrigerant issue, an oversized or undersized system, or a controls problem that is putting the equipment through unnecessary wear. Left alone, it shortens the life of the compressor and the heat exchanger. We check refrigerant, airflow, and controls before drawing any conclusion about what the fix involves.
A cracked heat exchanger in a gas furnace is one of the more serious findings a diagnostic visit can turn up. The heat exchanger separates combustion gases from the air circulating through the home, and a crack in it means those gases can enter the living space without any obvious outward sign. If a furnace is producing carbon monoxide readings, running inconsistently, or showing visible rust or stress around the heat exchanger casing, that part of the system needs to be looked at directly before the furnace is cleared to run another season.
Older multi-story buildings and row houses in this part of Massachusetts were often built with duct layouts that made sense for the original heating system and nothing else. A central air system added later, or a furnace replacement that changed the air volume moving through the ducts, can leave some rooms over-conditioned and others barely reached. Rebalancing the registers and, where needed, adjusting dampers in the duct system is the right fix for that problem. It is faster and cheaper than replacing equipment that is actually working fine.
A home that has never had central air, or one where window units have been the only option, can often take a ducted central system if the duct layout is right for it. We assess the existing ductwork, size the equipment for the space, and install the system including the air handler, the outdoor condenser, and the thermostat and controls. The thermostat is confirmed as communicating before sign-off on every installation.
When a system has reached the end of its useful life, replacement is the conversation that matters. We go over equipment options appropriate for the space, the full scope of the installation, and the cost before anything is ordered. The old equipment comes out as part of the job. The new system is installed, tested through a full operating cycle, and confirmed before we leave.
An addition that was finished without extending the duct system properly is one of the most common sources of comfort complaints in older homes. The room is either always too hot or always too cold because the existing system was never sized to cover it. We design and install the ductwork needed to bring the addition into the conditioned space properly, which sometimes means rerouting supply and return runs rather than just adding a register at the nearest point.
Ductless mini-split systems solve a specific problem: a space that needs heating and cooling but has no practical path for ductwork. That covers finished attic rooms, basement conversions, additions built onto older homes, and garden-level units in multi-family buildings where running duct through the structure would mean tearing out finished walls. A mini-split handles both heating and cooling from a single system, with an indoor air handler mounted in the space and an outdoor unit sited for airflow and access.
Multi-zone mini-split systems work well for small commercial spaces and mixed-use buildings where different areas need independent temperature control. A retail space that runs warm from customer traffic and a back office that runs cold from equipment are a straightforward application. We install single-zone and multi-zone systems and configure the controls for how the space actually operates. Care is taken with floors and finishes on every visit, which matters in occupied spaces where the work is happening around people.
We take calls every day from 7:00 AM to 10:00 PM, including for emergency no-heat and no-cool situations within those hours. If a property has no heating on a cold night or no cooling during a stretch of humid summer weather, that is exactly the kind of call we handle. The scope gets discussed on the phone so the visit is prepared before anyone arrives.
For properties that are occupied by tenants or that need to stay open for business, we discuss scheduling on the call. A rental unit that needs heat restored, a commercial space that cannot close for a full day, or a building manager coordinating access across multiple units: these are situations we work through when the job is booked, not after someone has already shown up. We'll get your comfort back on track.
HVAC pricing moves with the job. A refrigerant recharge is a different call from a heat exchanger replacement, and a full system installation is a different conversation from a vent rebalancing. What the fault turns out to be, what parts of the system have to be accessed, and whether a repair or a replacement is the right answer are the things that move a quote in either direction.
When you call, the scope gets discussed and a price is confirmed before anything is scheduled. If the diagnostic turns up something different from what the call described, the findings are explained before any repair is quoted. You are told what the visit covers. You are told what the repair involves. Nothing is ordered or replaced without a clear conversation about why it is needed and what it costs.
Ask what it covers and you get a straight answer. Diagnosed properly. Explained clearly. Priced before the work.
We serve Somerville and the surrounding communities across Middlesex County. That includes Cambridge, Medford, Everett, Malden, and Chelsea.
If you are in one of those areas or nearby and need heating or cooling work done, call (978) 992-9593 and we will confirm coverage for your address.
We work with homeowners, property managers, building owners, and commercial tenants throughout the area. The coverage question is always answered on the call, before anything is scheduled. Anything not covered here is on our heating and cooling services page.
Scheduling around an operating business is something we discuss on the call. We work through what access looks like, which parts of the system need to be reached, and how to sequence the work so the space stays usable. There is no single answer that fits every situation, which is why the conversation happens before anyone shows up.
Start with a call. Describe what the building has, how many units are involved, and what the comfort complaints are. We will scope an assessment that looks at the equipment, the duct layout or lack of one, and the controls before any recommendation is made. A building with a complicated history needs a diagnostic that works through the whole system, not a quote based on assumptions.
A burning smell that does not clear within a few minutes of the system starting, or one that smells electrical rather than dusty, is a reason to switch the system off at the thermostat and call us. Dust burning off at the start of the heating season is normal and usually brief. A persistent or sharp burning smell is not.
Yes. We work on hydronic boiler systems and ductless mini-splits as separate equipment types, and a building that has both is not unusual in this part of Massachusetts. When you call, describe the setup and we will scope the visit to cover what needs attention. If the two systems need to be looked at on the same call, that gets confirmed when the job is booked.
A system that is showing early signs of trouble is easier and less expensive to deal with than one that has already failed. Pre-season maintenance, a diagnostic on a system that has been running inconsistently, or a planned replacement before an aging unit quits mid-winter: these are the calls worth making now rather than later.
Call (978) 992-9593 to get a quote on any heating or cooling job.
We are available every day from 7:00 AM to 10:00 PM. We are ready when you are.

Below is a plain look at the heating and cooling work we handle across Somerville and Middlesex County. Each service is described by what it covers, who it fits best, and one practical detail worth knowing before you call. If a job on this list sounds like what you need, call us and we will scope it out before anything is scheduled.
| System Service | What It Covers | Common Needs | Helpful Details |
|---|---|---|---|
| AC Repair & Service |
| Homeowners and commercial tenants with an AC running but not cooling, or not running at all | Humid Massachusetts summers put real load on cooling equipment. A system that short-cycles or blows warm air is worth diagnosing before the peak of the season. |
| Full System Installation & Replacement |
| Homeowners and building owners replacing an aging or failed HVAC system, or upgrading to a properly sized unit | When both the heating and cooling sides are being replaced at once, sizing the new system correctly for the space is the most important step. We go over the equipment options and the full scope before anything is ordered. |
| Emergency HVAC Service |
| Any home or business with no heat on a cold night or no cooling during a heat event | We take emergency calls every day from 7:00 AM to 10:00 PM. Describe what the system is doing when you call and we will work through the options with you before anyone is dispatched. |
