The most common call we get from a town like Dennis is a heating system that has stopped working: a boiler that lost pressure overnight, a furnace that will not ignite, or a heat pump that is running but not producing heat. Older homes on the Cape are often on their original heating equipment, and when that equipment fails, it tends to fail without much warning. We handle that call, and we handle everything around it, from a quick diagnostic visit to a full system replacement.
We cover Dennis and the surrounding area for the full range of heating and cooling work. That includes AC repair, boiler and hydronic heating service, heat pump installation and repair, ductless mini-split installation, ductwork repair, indoor air quality work, and seasonal maintenance. Whether the property is a year-round home, a seasonal rental, or a small commercial building, the work is the same: figure out what the system needs and get it handled.
Getting your comfort problem handled starts with a quick call. When you call, you reach someone who knows the trade and can talk through what the system is doing before anything is booked. That conversation is where the scope of the visit gets settled and the price gets confirmed. You do not need to know what is wrong before you call.
When a property has no heat or no cooling at all, that call moves to the front. We take last-minute comfort calls seriously, and we are available every day from 7:30 AM to 8:30 PM. Describe what the system is doing, or not doing, and we will work to get someone out as quickly as the schedule allows.
A rental property or a small business that has to stay open during a service call needs the visit planned around the people inside. We confirm the scope and the timing on the phone before anyone comes out. If the situation calls for a phased approach, that gets worked out before the first visit, not after.
A full system replacement is not a decision that has to be made in a hurry, and we are honest about when a system still has life in it. If a repair makes more sense than a replacement, that is what we will tell you. Second opinions on replacement quotes are welcomed.
When replacement is the right call, the process starts with sizing the new equipment correctly for the space. A system that is oversized short-cycles and wears out faster. One that is undersized runs constantly and still does not keep up. Getting that right at the outset is the most important part of the job.
For most residential properties in this area, a full replacement means a day without the system running. The exact timing depends on what is being removed, what is going in, and whether any ductwork or wiring at the unit needs attention. Those details are worked out on the call before anything is scheduled, so the property owner or tenant knows what to expect.
When airflow drops across the house, or certain rooms stop receiving conditioned air, the air handler and blower motor are the first places to look. A blower motor that is running slow, drawing too much current, or making a grinding noise is usually close to the end of its service life. The air handler visit covers the motor, the wheel, the capacitor, and the evaporator coil. A dirty evaporator coil restricts airflow and reduces the system's ability to transfer heat, and cleaning it is part of a thorough air handler inspection.
A maintenance visit before the cooling season and another before the heating season starts are the most practical way to catch a developing fault before it becomes a breakdown. A spring tune-up covers refrigerant pressure, coil condition, electrical connections on the unit, and airflow through the system. A fall tune-up covers the heat exchanger, igniter, burner assembly, and blower. For heat pumps, both visits include the defrost controls and the reversing valve. On the Cape, the shoulder seasons are long enough that a system can be asked to heat and cool in the same month, and a tune-up in both seasons keeps it ready for that.
When the equipment has reached the end of its useful life, replacement is a different kind of job from a repair call. It starts with an honest assessment of what the home actually needs, not just a swap of the same equipment that came out. In a non-ducted home, that conversation may lead toward a ductless heat pump rather than a traditional central system. In a home with existing ductwork, a duct inspection is part of the process, because new equipment installed into a leaking duct system will never perform the way it should.
A burning smell when a furnace or air handler first runs in the season is sometimes dust burning off a heat exchanger that has been idle for months. If the smell persists past the first few minutes, or comes back on subsequent cycles, that is a different situation and worth a diagnostic visit. A musty smell usually points to microbial growth on the evaporator coil or inside the air handler, which an evaporator coil cleaning and an air quality assessment can address. Neither smell should be ignored, and both are easier to deal with before they develop into a larger problem.
A furnace that will not ignite, trips its limit switch repeatedly, or blows cold air is one of the most common calls we take in this region. The diagnostic covers the igniter, flame sensor, heat exchanger, limit switch, and the sequence of operation from thermostat call to burner start. Furnace short-cycling in particular can have several different causes, and finding the right one before quoting parts is the difference between a repair that holds and one that comes back. Comfort problems don't wait, and calls about heating are taken as soon as the schedule allows.
Most homeowners can't tell a minor HVAC issue from a serious one, and that is exactly what the phone call is for. When you call, we will ask what the system is doing, how old it is if you know, and whether anything has changed recently, a new thermostat, a recent service call, or a change in how the system sounds or performs. That information lets us scope the visit correctly before anyone comes out.
The diagnostic fee and the scope of the visit are both confirmed on the phone before anything is booked. If the visit turns up something that changes the scope, we talk through it before any additional work moves forward. The price you agree to on the call is the price the visit covers. Call us and we'll walk you through your options.
Pricing depends on what the system needs, and the only way to give an accurate number is to understand the job. A repair quote depends on what the fault turns out to be, which components need to reach, and whether a single part or a sequence of related faults is involved. A replacement quote depends on the equipment selected, the scope of the installation, and what the existing setup requires.
What would change a quote: discovering a secondary fault during the diagnostic, a duct system that needs work before new equipment can be installed correctly, or a refrigerant type that affects the parts available for a repair. Those possibilities are discussed before the work proceeds, not after. Ask what the quote covers and you will get a straight answer.
We serve Dennis and the neighboring communities throughout Barnstable County, including Yarmouth Port, East Dennis, South Dennis, Yarmouth, and South Yarmouth. If you are in the area and need heating or cooling work handled, call and we will confirm your address is within our service range. Most of the Cape is covered. Plenty of Dennis jobs start with a look at the list of HVAC services we handle.
Yes. Air filtration equipment installed in line with the HVAC system has its own service requirements, including filter media replacement and periodic checks of the unit itself. We can include that in a maintenance visit or schedule it separately depending on what the equipment requires.
If the outdoor unit is running but there is no airflow at the registers, the problem is most likely inside the house. A failed blower motor, a tripped internal safety switch, or a control fault can stop the air handler from running even when the outdoor unit is operating. The diagnostic covers both sides of the system.
Many homes in Dennis were built before central forced-air systems were standard, which means the heating equipment is often a boiler connected to baseboard radiators rather than a furnace with ductwork. That changes the diagnostic process, the parts involved, and what a replacement looks like. When you call, let us know what type of heating system the property has and we will scope the visit around it.
Run the system for a few minutes and see whether the smell clears. Dust burning off a heat exchanger that has been idle for months is common and usually resolves quickly.
If the smell comes back on the next cycle, or does not clear within the first few minutes, shut the system off and call us at (774) 822-6289.
A persistent burning smell from a furnace or air handler points to a fault worth diagnosing before the system runs again.
The scoping conversation happens on the call. When you describe what the system is doing, we can tell you what the diagnostic visit will cover and what it is likely to cost, so you are making an informed decision before anything is scheduled.
Yes, though it may take longer. A fault that only shows up after the system has been running for some time is often a thermal issue, where a component behaves differently once it reaches operating temperature. The technician will run the system long enough to reproduce the fault before drawing a conclusion.
When the heat goes out or the air conditioning stops keeping up, the next step is a phone call, not a form and a wait.
Call (774) 822-6289 any day from 7:30 AM to 8:30 PM.
We will talk through the situation, confirm the scope and the price, and get someone scheduled. One number. One call. One HVAC tech at your door.
