Every home's heating and cooling setup tells a different story, and the work changes with it. A 1960s Cape Cod ranch with hot-water baseboard heat is a different job from a newer build with a central heat pump, and a commercial property with rooftop units is different again. We handle all of it, for homeowners, landlords, property managers, and businesses across the area. Call us and we'll walk you through your options.
When the air conditioner stops cooling, the first step is a proper diagnosis before anything gets replaced. A visit covers refrigerant leak diagnosis, coil cleaning, airflow checks, and short-cycling diagnosis. An AC blowing warm air or freezing up often has a straightforward cause, and the system gets checked before parts are quoted.
A furnace that won't turn on, blows cold air, or keeps shutting off needs a methodical look. The visit covers heat exchanger inspection, igniter and burner checks, and a full review of what the system is doing and why. Furnace short-cycling in particular can point to several different faults, and finding the right one matters before any work starts.
Heat pumps handle both heating and cooling, which means a fault can show up in either season. Common issues include the unit not heating or cooling adequately, refrigerant loss, a reversing valve that won't switch modes, and a defrost cycle that isn't clearing ice. We handle heat pump repair and new heat pump installation across residential and commercial properties.
A full system replacement is a significant decision, 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. When replacement is the right call, the visit covers proper sizing and equipment selection for the space, not just swapping in the same unit that came out.
Leaking or poorly sealed ducts waste conditioned air and create uneven temperatures from room to room. A ductwork inspection identifies where air is escaping, and duct sealing brings the system back to performing the way it should. Airflow problems are often misread as equipment problems, so checking the ducts is part of a thorough diagnosis.
A thermostat that isn't reading the temperature correctly, won't respond, or isn't communicating with the system can cause the whole setup to behave erratically. We handle smart thermostat installation, programmable thermostat setup, and thermostat replacement when the old one has reached the end of its useful life.
Older homes in the Hyannis area often have air sealing and ventilation patterns that affect indoor air quality year-round. Whole-home air filtration and air purifier installation work alongside the existing HVAC system to improve what the household is breathing. We also handle filter replacement and can advise on the right filtration level for the equipment already in place.
A spring tune-up before the cooling season and a fall tune-up before heating season starts are the most straightforward way to catch small problems before they turn into system failures. A maintenance visit covers coil cleaning, refrigerant level checks, burner and igniter inspection, and a full system run-through. Reach out and we will talk through the symptoms if something has already come up.
The housing stock on Cape Cod is among the oldest in the country, and it runs on equipment that reflects that history. Oil heat is the norm across much of the region, older homes rely on boilers and hot-water baseboard systems rather than forced air, and many properties have no ductwork at all. The equipment on site decides the work.
Hot-water baseboard and steam radiator systems are common throughout Hyannis and the surrounding Cape Cod towns. A boiler that's losing pressure, cycling off too quickly, or failing to heat certain zones is a job that requires familiarity with hydronic systems, not just forced-air equipment. A visit covers boiler repair, pressure checks, zone valve service, and boiler replacement when the unit is at the end of its service life.
Many properties in this area still run on oil heat, and conversion is one of the most common projects we handle. Whether the goal is switching to natural gas where it's available or replacing an oil system with a heat pump, the process starts with sizing the replacement correctly for the home's actual heat load. We handle the equipment changeover and can walk you through what the new system will and won't do before anything is scheduled.
A large share of Cape Cod homes were built without central ductwork, and adding it is often impractical in older construction. Ductless mini-split systems are a direct solution: individual air-handling units serve specific rooms or zones, with no ductwork required. They work for additions, seasonal rental properties, and whole-home conditioning in non-ducted houses. We handle mini-split installation, mini-split repair, and ductless AC installation across the area.
Comfort problems don't wait, and neither do we, especially when a heating system goes down in a coastal Massachusetts winter or the AC fails during a humid July on the Cape. Last-minute comfort calls are taken seriously. Whether the furnace won't turn on, the heat pump has stopped responding, or the AC has gone completely quiet, a call gets the process moving.
We are available every day from 7:30 AM to 8:30 PM. One number. One call. One HVAC tech at your door.
Call (774) 822-6289 when the system goes down.
Systems around here run into the same few faults, whether the building is a small retail space, a restaurant, a multi-unit property, or a larger commercial facility. We handle commercial HVAC repair, rooftop unit service, commercial heat pump repair, and scheduled maintenance for businesses and property managers across Hyannis and Barnstable County. Pricing is confirmed on the call before anything is scheduled, so there are no questions about what the visit covers. We'll get your building comfortable again fast.
Most homeowners can't tell a minor HVAC issue from a serious one, and that uncertainty makes the pricing question feel harder than it needs to be. When you call, you get a clear explanation of what the service call covers and what the rate is before anything is booked. The diagnostic fee and the scope of the visit are both explained up front.
Second opinions on replacement quotes are welcomed. If another contractor has told you the system needs to be replaced, we are glad to take a look and give you a straight read on what we find. The assessment starts with the equipment, not with the invoice.
We serve Hyannis and the communities throughout Barnstable County, including Barnstable, Yarmouth, Dennis, Falmouth, Mashpee, Sandwich, Centerville, and Osterville. If you are in the area and need heating or cooling work handled, call and we will confirm whether your address falls within our service range.
Check the thermostat settings and the circuit breaker for the unit first, then call us at (774) 822-6289 if the system is still unresponsive.
We take calls every day from 7:30 AM to 8:30 PM, including weekends, and we treat no-heat and no-cool calls as the urgent situations they are. Describe what the system is doing when you call, and we will scope the problem on the phone before anyone is dispatched.
Yes, we work on both residential and commercial properties across Hyannis and Barnstable County. Commercial calls cover rooftop unit repair, commercial heat pump service, air handler work, and scheduled maintenance for retail spaces, offices, and multi-unit buildings. The process is the same on both sides: scope confirmed on the call, price agreed before anything is scheduled.
It helps to know the age of the system if you can find it, the make and model on the equipment label, and a description of what the system is doing or not doing. If the system has had recent service, mention that too, since it helps narrow down what the fault is likely to be. You do not need to diagnose the problem yourself before you call.
A pattern of repeated failures usually means the equipment is past the point where repair is the right answer. When that comes up, we lay out the repair cost alongside what a replacement would involve so you can make the decision with both numbers in front of you. We are honest about when a system still has life in it, and equally honest when it does not.
The price is confirmed before anything is scheduled, and the scope of the visit is settled on the call. If the scope changes once the work is underway, we talk through it before anything moves forward. What you agree to on the phone is what the visit covers.
Second opinions on replacement quotes are welcomed. Call us, describe the system and what you were told, and we will schedule a visit to look at the equipment and give you a straight read on what we find. The assessment starts with what the system is actually doing, not with what the invoice might look like.
Turn the system off at the thermostat and call us. A burning smell from a furnace or air handler can point to an overheating motor, a failing electrical component on the unit, or debris in the heat exchanger. A loud banging or grinding noise from the outdoor unit often means a mechanical fault that gets worse the longer the system runs.
We cover all of Barnstable County, including Barnstable, Yarmouth, Dennis, Falmouth, Mashpee, Sandwich, Centerville, and Osterville. If you are unsure whether your address falls within our service area, call and we will confirm it on the spot. Most of the Cape is within our range.
We are available every day from 7:30 AM to 8:30 PM, including weekends and holidays. That window covers both scheduled maintenance visits and urgent repair calls.
Call (774) 822-6289 to book a visit or ask what the schedule allows for short-notice calls.
Yes. When you call, you reach someone who knows the trade and can ask the right questions about your system. That conversation is where the scope and the price get worked out, so it matters that the person on the phone can actually talk through what your system is doing.
Getting your comfort problem handled starts with a quick call. Hyannis HVAC Company is available every day from 7:30 AM to 8:30 PM for repair, installation, maintenance, and emergency service across the Cape Cod area.

Every heating and cooling job on Cape Cod starts with the same question: what does this system actually need? We cover the full range of HVAC work across Hyannis and Barnstable County, from a single repair call to a full system changeout, and we confirm the price before anything is scheduled. The table below lays out what each service covers and who it fits best.
| Service Type | What's Included | When You Need It | What to Keep in Mind |
|---|---|---|---|
| Oil-to-Heat-Pump Conversion | Heat load calculation for the home, Oil equipment removal, Cold-climate heat pump installation, Ductless option scoping for homes without ducts | Barnstable County homeowners looking to move off fuel oil and take advantage of Massachusetts electrification incentives | Sizing the replacement equipment correctly matters more than the equipment brand. We base sizing on the home's actual heat load, not the capacity of the old oil system. |
| Full System Installation & ReplacementMost Popular | Equipment sizing for the space, Removal of existing system, Installation and startup, Thermostat integration and testing | Homeowners whose system has aged past the point where repair makes financial sense, or properties being upgraded from older equipment | We welcome second opinions on replacement quotes. We look at the equipment and run the numbers before any work is scheduled. |
| Emergency HVAC Service | Urgent repair calls handled as quickly as the schedule allows, No-heat and no-cool response, System-down diagnostic, Priority scheduling within available hours | Anyone with no heat in winter, no cooling during an extreme heat stretch, or a system that has shut down and will not restart | We take urgent calls every day from 7:30 AM to 8:30 PM. Describe the situation when you call and we will work to get someone out as quickly as the schedule allows. |
| Heating & Furnace Repair | Igniter and flame sensor check, Heat exchanger inspection, Blower motor assessment, Limit switch and control board review | Anyone with a furnace that will not start, blows cold air, or shuts itself off mid-cycle | A tripped limit switch is one of the most common no-heat calls and is often a symptom of an airflow problem rather than a failed part. |
| Ductless Mini-Split Installation | Outdoor and indoor unit mounting, Refrigerant line set installation, Heating and cooling mode startup testing, Multi-zone configuration where applicable | Cape Cod homes without existing ductwork, additions, seasonal cottages, and whole-home retrofits where running ducts is not practical | A mini-split handles both heating and cooling through a small wall penetration. No ductwork renovation is required, which keeps the installation scope manageable. |
| Indoor Air Quality & Air Filtration | Air filtration system installation, Air purifier integration with existing HVAC, Humidity and odor assessment, Filter media selection for the space | Households dealing with dust buildup, persistent odors, or humidity complaints that follow the HVAC system | The right filtration setup depends on what the home is actually experiencing. We walk through the options before anything is installed. |
| Heat Pump Repair & Service | Reversing valve and defrost control check, Refrigerant pressure reading, Heating and cooling mode testing, Electrical circuit inspection on the unit | Homes relying on a heat pump year-round that lose heating in winter or cooling in summer | A heat pump stuck in one mode often has a reversing valve fault rather than a compressor problem. The diagnostic distinguishes between the two. |
| Ductwork Repair & Sealing | Duct system inspection and pressurization, Leak identification and sealing, Damaged section replacement, Airflow verification after sealing | Homes with uneven temperatures between rooms, a system that runs constantly, or rising energy bills without a change in usage | Leaking duct joints waste conditioned air in unconditioned spaces. Sealing them is one of the more cost-effective improvements on a home with older ductwork. |
| Boiler & Hydronic Heating Service | Zone valve and circulator pump inspection, Pressure and temperature relief valve check, Expansion tank assessment, Heat distribution troubleshooting | Older Cape Cod homes that heat with oil-fired or gas boilers connected to radiators or radiant systems | Uneven heat distribution in a hydronic system is often a zone valve or circulator issue rather than a boiler fault. The diagnostic checks both before quoting repairs. |
| Thermostat Installation & Smart Controls | Programmable and smart thermostat installation, Compatibility check with existing equipment, Scheduling and zoning setup, System communication verification | Homeowners with a thermostat that misreads temperature, fails to respond, or cannot communicate with the system | A smart thermostat that is not configured properly offers little benefit. Setup includes making the scheduling and zoning features actually usable. |
| Seasonal Maintenance & Tune-Ups | Coil cleaning and refrigerant pressure check, Burner, igniter, and heat exchanger review, Electrical connection inspection, Filter check and system report | Homeowners who want to catch a failing component before it becomes a breakdown call in peak season | On Cape Cod, the shoulder seasons are long enough that a system can shift between heating and cooling in the same month. Tuning up in both seasons keeps it ready. |
| AC Repair & Service | Diagnostic visit for cooling faults, Refrigerant pressure check, Electrical and control inspection, Coil and airflow assessment | Homeowners and landlords dealing with a system that runs but will not cool, freezes up, or short-cycles | A frozen coil and warm air from the vents often trace back to two different causes. The diagnostic covers both before any repair is quoted. |
