When a heating or cooling system stops doing its job, the visit is where everything gets resolved. The technician works through the system methodically: readings taken, pressures checked, components inspected in sequence until the fault is clear. Only then is the repair scoped and the price confirmed. That process does not change based on the size of the property or the age of the equipment, and it is the same whether the call comes in on a mild spring morning or in the middle of a hard summer stretch.
We handle heating and cooling work throughout Keene and the surrounding Johnson County area. Homes here tend to run on equipment that works hard through both ends of the calendar, and a system that holds up through a humid summer still has to fire reliably when winter arrives. We're available every day from 7:00 AM to 10:30 PM.

Heating and cooling a home right takes the right tools and a methodical approach, and the jobs that come up in a town this size reflect that. Older equipment, rooms that never quite reached the right temperature, systems that have not had a tune-up in years: those are the calls we get, and each one starts with a proper diagnosis before anything is recommended.
A dirty or damaged evaporator coil is one of the more common reasons an air conditioner runs but does not cool. The coil sits inside the air handler and pulls heat out of the air passing over it. When it is coated in dust and debris, or when it develops a leak, the system works harder and delivers less. The visit covers a visual inspection, cleaning if that is what is needed, and a check of the refrigerant charge once the coil is clear. If the coil has a leak, the repair is scoped and priced before any work begins.
A smell when the system kicks on is the kind of thing people notice and then put off calling about. A burning smell at the start of the heating season often means dust burning off the heat exchanger, but it can also point to an electrical fault in the blower or control board. A musty smell usually comes from moisture sitting in the ductwork or on the evaporator coil, which is a separate problem with a different fix. Either way, the smell is telling you something the system is not, and a diagnostic visit identifies which one it is.
These are the components that fail quietly and take the whole system down with them. A capacitor that is weakening will cause the motor it supports to struggle at startup and eventually stop starting at all. A failing contactor can prevent the outdoor unit from turning on even when the thermostat is calling for cooling. A control board fault can produce almost any symptom, which is why it is diagnosed last rather than first. We work through the more likely causes before condemning a board, because the repair cost is different and the diagnosis matters.
Standard one-inch filters do a reasonable job of keeping the equipment clean, but they do not address what the people in the house are breathing. Whole-home filtration upgrades, air purifier installation, and media filter replacements all fall under this work. The right solution depends on what the existing system can support and what the property needs. We scope that on the call and confirm the work before scheduling.
Don't let a small problem turn into a no-heat night or a no-cool afternoon. Airflow and uneven-temperature problems often trace back to a combination of equipment faults and duct issues, and catching them early is almost always less disruptive than waiting for a breakdown.
A system that stops working is not a call to schedule for next week. We take emergency calls every day from 7:00 AM to 10:30 PM, and a no-heat or no-cool situation is treated as urgent from the first conversation. The job is scoped on the phone as far as it can be, and the visit is arranged from there.
For non-emergency calls, appointments are set around what works for the property. If there is a tenant in the home, or a business that has to stay open during the visit, that is part of the scheduling conversation. We confirm the scope and the rate before the visit is booked, so there is no ambiguity about what the appointment covers. We keep you posted from the first call until your system's running again.
For rental properties in and around Keene, a landlord or property manager does not need to be on-site for most visits, but the scope and authorization are confirmed on the call before anyone comes out.
A filtration upgrade changes what circulates through the house every time the system runs. Higher-efficiency filters and media cabinets capture more of what a standard filter passes through, which matters most for households dealing with dust, pet dander, or allergy symptoms that get worse indoors. The installation connects to the existing air handler, and the filter type is matched to what the system's airflow can support.
In a humid regional climate, an air conditioner removes some moisture as a byproduct of cooling, but that is not always enough. When the indoor air still feels heavy at the set temperature, a whole-home dehumidifier integrated with the HVAC system lets you set a humidity target independently of the thermostat. That combination addresses both the temperature and the moisture load, and the benefit carries through the shoulder seasons when the AC is not running as often.
A full system replacement is a bigger conversation than a repair call, and it starts the same way: with a clear picture of what is installed, what condition it is in, and what the replacement options look like for that specific property.
For most homes, replacing one half of a paired system means evaluating the other half at the same time. A new air conditioner paired with an aging furnace, or a new furnace paired with a condenser that is close to the end of its life, is a setup that often leads to a second replacement call within a season or two. The visit covers both units and the ductwork that connects them, so the recommendation reflects the whole system rather than just the part that failed.
The staging of the job is discussed on the call. Most residential replacements are completed in a single visit, but the timeframe depends on what is coming out, what is going in, and whether the duct system needs any adjustment to support the new equipment. The property is without heating or cooling for the duration of the installation, and that window is part of the scheduling conversation.
Heat pump installation is worth considering for properties where the existing heating equipment is at the end of its useful life. The regional climate here suits heat pump operation well for most of the heating season, and a single system that handles both heating and cooling simplifies what the property runs on.
The rate is given on the call, before anything is scheduled. What moves it is what the diagnostic finds: the fault itself, where it sits in the system, what has to be accessed to reach it, and whether a repair or a replacement is the better answer for that equipment at that age.
For a repair call, the price is confirmed after the technician identifies the fault, before any work begins. For a replacement or installation, the scope is worked out from the details of the property and confirmed before scheduling. Either way, you know the rate and what it covers before anyone comes out.
What can add to the scope is anything the diagnostic uncovers that was not visible on the call: a refrigerant leak that requires recovery and recharge, ductwork that needs attention for the repair to hold, or a second component that has failed alongside the one that caused the symptom. Those are identified during the visit and priced before the work continues.
Diagnosed properly. Explained clearly. Priced before the work.
The most useful thing to have ready is a description of what the system is doing: whether it is not turning on at all, running but not heating or cooling, making a noise that was not there before, or tripping the thermostat repeatedly. How long the problem has been happening and whether it came on suddenly or gradually helps scope the visit more accurately.
We will ask about the type of system, roughly how old it is if you know, and whether the problem affects the whole house or just part of it. Rising energy bills are worth mentioning too, because a system that is working harder than it used to often has a reason that shows up in the diagnostic.
The call takes a few minutes. The scope and rate are confirmed before anything is booked, so you are not waiting for a visit to find out what the job involves.

It can, but it depends on the age and condition of the half being kept. Replacing only the outdoor condenser or only the indoor air handler on a mismatched system can cause efficiency and compatibility problems, and the older half may fail within a season anyway. We scope that question on the call and give you a straight answer about whether a partial replacement makes sense for your specific equipment.
Yes. When a system is replaced, the old equipment comes out as part of the installation job. You do not need to arrange separate disposal. What happens to the old equipment is handled on our end.
The scope and rate are confirmed on the call before the visit is booked, so you can authorize the work without needing to be on-site. We confirm what the appointment covers, and the technician works through the fault and prices the repair before anything begins. If the tenant needs to be present or if access needs to be arranged, that is part of the scheduling conversation when you call.
Older homes often have equipment that has been running for a long time without a tune-up, duct runs that were never properly sealed, or systems that were sized for a different layout than what the house is now. Those factors come up in the diagnostic and shape what the repair or replacement involves. We scope the job based on what is actually installed, not on assumptions about what a house of a certain age should have.
Call (682) 245-5395 and we will ask a few questions about what the system is doing.
