Marana HVAC Company handles the full range of residential and commercial heating and cooling work across Marana and Pima County. From a furnace that stopped firing on a January night to an air conditioner that quit in the middle of a 108-degree July, we scope the job on the phone, confirm the price before anything is scheduled, and get the work done right. We keep you posted from the first call until your system's running again.

Every home's heating and cooling setup tells a different story, and the same is true for commercial properties. We work on all of it: AC repair and service, heating and furnace repair, heat pump repair and installation, mini-split and ductless systems, full HVAC system installation and replacement, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality and air filtration, and seasonal maintenance and tune-ups.
Homeowners call when something breaks or when a system is aging out. Property managers and landlords call when a tenant has no heat or no cooling and the clock is running. Office and retail managers call when a commercial unit is underperforming and the space is uncomfortable. Whatever the situation, the job gets scoped on the phone and handled from there.
Making comfort simple is most of what the job is, and in Marana that means keeping the air conditioner running through a long, punishing cooling season. When a system stops cooling or starts blowing warm air, a repair visit covers the full picture: refrigerant charge, condenser and evaporator coil condition, airflow through the air handler, and thermostat response. The system gets checked before parts are quoted, so you know what you're actually paying for.
Common calls include AC not cooling, AC blowing warm or hot air, a unit that cycles on and off without reaching temperature, and systems that simply stop responding. Scheduling a spring tune-up before the heat arrives is the most straightforward way to catch a low refrigerant charge or a worn capacitor before it becomes a mid-summer failure.
Reach out and we'll work out what it needs.
Whether it's a one-time repair or a full system replacement, a heating call in Marana usually comes in on the handful of cold nights the desert delivers each winter. When a furnace stops heating or blows cold air, the visit covers ignition components, heat exchanger condition, airflow through the system, and whether the thermostat is communicating correctly with the unit.
Heating repair applies to gas furnaces and electric air handlers alike. Symptoms vary: furnace not turning on, furnace running but not heating, no heat in the house at all, or a system that short-cycles and shuts off before the space warms up. Fall maintenance is worth scheduling before the first cold snap, because a furnace that sat idle through a long Arizona summer can surface problems that weren't there in spring.
We'll get the repair scoped and scheduled.
A heat pump handles both heating and cooling from a single outdoor unit, which makes it a practical fit for a climate where the heating season is short and the cooling season is long. When a heat pump stops working in either mode, the visit covers refrigerant diagnosis, reversing valve operation, coil condition, and airflow through the air handler. A unit that heats fine but won't cool, or cools fine but won't switch over to heat, often points to the reversing valve or refrigerant circuit rather than a full system failure.
Installation and replacement visits start with sizing the unit to the space. A heat pump that's oversized for the home short-cycles and wears faster. One that's undersized runs continuously and still falls short on the hottest days.
Give us a call and we will take care of it.
Marana's desert climate puts specific demands on heating and cooling equipment that don't apply the same way in other parts of the country. Summers are long, intense, and mostly dry, with stretches above 100 degrees that run from late spring through early fall. The housing stock here includes a mix of older evaporative systems and newer refrigerated setups, and knowing how to work on both is part of doing this job in this area. The monsoon season adds a complication: humidity levels that rise enough to push evaporative coolers past their effective range, which is driving more homeowners toward refrigerated systems than in previous years.
Evaporative coolers work by pulling outside air through water-saturated pads, dropping the temperature through evaporation. In Marana's dry heat, that process is genuinely effective and far less expensive to run than a refrigerated system. A service visit covers pad inspection and replacement, pump and motor condition, water distribution lines, belt tension, and seasonal startup or shutdown. Common symptoms that prompt a call include reduced airflow, a musty smell coming through the vents, water pooling around the unit, or a cooler that runs but doesn't drop the indoor temperature the way it used to. Keeping the pads and pump in good shape is what separates a cooler that works from one that just moves warm air.
During the monsoon weeks, when outdoor humidity climbs, evaporative coolers lose most of their effectiveness. The physics stop working: if the air is already carrying significant moisture, adding more through evaporation barely drops the temperature. That's the moment most homeowners start thinking seriously about a conversion. The process involves removing the evaporative unit, installing a refrigerated system sized to the home's square footage and existing ductwork, and verifying airflow to every room. The result is whole-home cooling that works regardless of what the humidity is doing outside, with thermostat control and consistent temperatures from room to room.
Marana's mild winters make heat pumps a particularly practical choice. Heating demand here is low enough that a heat pump rarely gets pushed past the outdoor temperature range where it operates efficiently. A single system handles both the cooling season and the heating season without a separate furnace. Installation starts with a load calculation to size the unit correctly, followed by equipment selection and a check of the existing ductwork. For spaces without ductwork, a ductless mini-split path is often the cleaner solution.
If you've never hired an HVAC company before, the replacement conversation can feel uncertain. The honest version is straightforward: replacement makes sense when a system is old enough that repair costs are climbing toward what a new unit would cost, when the refrigerant type is being phased out, or when the system has failed repeatedly in a short period. A replacement visit starts with a load calculation to confirm the right equipment size, followed by removal of the existing system, installation of the new unit, and airflow verification throughout the home or building.
Mini-split and ductless systems are worth considering for spaces without existing ductwork, for additions, or for commercial areas that need independent temperature control. Reach out and we'll work out what it needs.
Leaking or poorly sealed ducts push conditioned air into attic space and wall cavities instead of into the rooms you're trying to cool or heat. A duct inspection visit identifies where air is escaping and seals the problem at the source, which usually shows up immediately in how evenly the space cools.
Thermostat and smart-control installation is a straightforward upgrade that pays off in comfort and energy use. A programmable or smart thermostat lets you set temperature schedules around occupancy, which matters more in a climate where the difference between indoor and outdoor temperatures can be 40 degrees. The installation covers wiring the new control to the existing system and confirming it communicates correctly with the air handler and outdoor unit.
Indoor air quality systems, including air filtration upgrades, UV air purifiers, and air scrubbers, attach to the existing HVAC equipment and address dust, allergens, and airborne particles that circulate every time the system runs. In a desert environment where windows stay closed for months, what the air handler pulls through the system matters.
Call and we'll get the air running right.
Property managers have a different problem from homeowners, but the maintenance answer is the same: a system that gets checked before the season starts is far less likely to fail in the middle of it. A tune-up covers coil cleaning, refrigerant charge verification, electrical connection checks on the unit's control board, blower and air handler inspection, and thermostat calibration.
In Marana's climate, the spring AC tune-up matters most. A system that sat through winter and then gets switched on in late April without a check is working from an unknown baseline. We treat your home and its system the way we would our own, which means the inspection covers what actually needs attention rather than what's easiest to bill. Commercial clients, including retail spaces, office buildings, and warehouses, can schedule maintenance visits around their operating hours.
No guesswork. No shortcuts. No rushed diagnosis.
When a system goes down completely, no cooling during a Marana summer and no heat on a cold desert night are both situations that need attention the same day. Emergency calls are answered seriously. The job gets scoped on the phone so the visit is prepared before anyone arrives, and the situation is prioritized accordingly. We take emergency no-heat and no-cool calls seriously, because a house at 90 degrees indoors or a furnace that won't fire at midnight are not problems that wait well.
We're available every day from 7:00 AM to 10:30 PM. Give us a call and we will take care of it.
No pressure and no gimmicks, just straight HVAC answers. When you call, the job gets scoped on the phone: what the system is doing, what symptoms you're seeing, and what the visit will cover. You get the rate before anything is scheduled, and you can ask what it includes and get a direct answer.
That applies across the range of work, whether it's a repair call on a system that stopped cooling, a tune-up before the season starts, a full system replacement, or commercial HVAC service on a larger property. The price is confirmed before we schedule, so there's nothing to figure out after the fact.
We serve Marana as the primary service area and take calls from throughout the surrounding Pima County region. That includes Tucson, Oro Valley, Catalina, Picture Rocks, Flowing Wells, and Sahuarita. If you're in the area and need heating or cooling work handled, call and we'll confirm coverage when you reach us.
Call (520) 462-9956 and we will scope the job on the phone.
That covers what the system is doing, what symptoms you are seeing, and what the visit will involve. You get the price before anything is scheduled, so there is nothing to figure out after the fact.
It helps to know the make and model of your system if you can find it, the symptoms you are seeing, and roughly how long the problem has been happening. If the system has had recent repairs, that information is useful too. The more detail you can give on the call, the more accurately we can scope the job and give you a price.
Someone should be available to provide access to the indoor unit, the furnace or air handler, and the outdoor condenser. If you cannot be there yourself, arrange for another adult to be present and make sure all access points are clear. Let us know the situation on the call and we will work out the details with you.
Yes, and it makes a real difference to how smoothly the visit goes. The person doing the work needs a clear path to the air handler or furnace inside and to the condenser unit outside. Moving stored items away from the equipment before the visit saves time and keeps the job on track.
When you call (520) 462-9956, the call is answered by someone who knows the trade and can talk through your situation.
You get answers on the call, not after a callback. We are available every day from 7:00 AM to 10:30 PM.
It depends on what the system needs, which is why the job gets scoped before anything is booked. A repair visit covers diagnosis and the fix. A tune-up covers coil cleaning, refrigerant verification, electrical connection checks, and thermostat calibration. A replacement visit covers removal of the old system, installation of the new equipment, and airflow verification throughout the space.
The price you get is based on the scope of work as described on the call. If the visit uncovers something different from what was described, we talk through it with you before proceeding. Nothing gets added to the job without your knowledge and agreement.
Cost varies based on the type of system, the scope of the repair or installation, and the equipment involved. A job that starts as a repair and reveals a larger underlying problem, like a failing compressor or a refrigerant leak alongside a coil issue, will change in scope. We walk through any changes with you before the work continues so you always know where things stand.
Routine maintenance and non-urgent repairs can usually be scheduled within a few days, though the spring AC tune-up season and the first cold weeks of fall are the busiest times of year in Pima County. For urgent repairs or emergency no-heat and no-cool situations, call and we will tell you what the schedule allows. Booking a seasonal tune-up before the heat season starts is the most straightforward way to avoid a long wait.

Every home and business in Marana puts different demands on its heating and cooling system, and the Sonoran Desert climate makes those demands real. We cover the full range of HVAC work, from a quick repair on a system that stopped cooling overnight to a full replacement or a swamp-cooler-to-refrigerated-AC conversion. The table below lays out what each service covers, who it fits best, and what is worth knowing before you call.
| Service | What's Included | Best For | What to Keep in Mind |
|---|---|---|---|
| Thermostat & Smart-Control Installation | Programmable thermostat setup, Smart thermostat wiring and configuration, Zoning control integration, System compatibility check | Homeowners who want more control over comfort and energy use without replacing the whole system | A smart thermostat paired with a properly sized system can reduce runtime during Marana's off-peak hours without sacrificing comfort when temperatures climb. |
| Indoor Air Quality & Air Filtration | Whole-house air filtration installation, Air purifier setup, Filter system upgrade, Indoor air quality assessment | Households dealing with dust, allergens, or air quality concerns, especially in a high-dust desert environment | Marana's desert air carries fine particulate that standard filters do not fully capture. A whole-house filtration upgrade works with the existing system rather than replacing it. |
| Heating & Furnace Repair | Ignition and flame sensor inspection, Heat exchanger check, Blower motor diagnosis, Control board and wiring review | Homeowners dealing with a furnace that won't turn on, runs but blows cold air, or short-cycles | Marana winters are mild, but a furnace that fails on a cold night still needs attention. Most furnace calls here involve ignition faults or airflow restrictions rather than heat exchanger failures. |
| Ductwork Repair & Sealing | Leak detection and sealing, Airflow measurement and balancing, Damaged duct section repair or replacement, Attic duct inspection | Homes with uneven temperatures, high energy bills, or rooms that never reach the set temperature | Attic temperatures in Marana can exceed 150 degrees in summer. A duct with even a small leak is dumping conditioned air into that heat, and the system pays for it every hour it runs. |
| Heat Pump Repair & Service | Refrigerant pressure check, Reversing valve diagnosis, Defrost cycle inspection, Thermostat and control wiring review | Homes running a heat pump year-round for both cooling and heating | A heat pump that heats in winter and cools in summer works harder across more months than a dedicated AC. Annual service catches wear before it shows up as a failure. |
| AC Repair & Service | Condenser and evaporator inspection, Refrigerant leak diagnosis, Capacitor and contactor checks, Airflow and cooling output testing | Homeowners and renters whose AC has stopped cooling or is underperforming in summer heat | In Marana's long cooling season, a system that is struggling in May will only get harder to manage by July. Early diagnosis keeps a small problem from becoming a full replacement. |
| Emergency HVAC Service | Diagnosis for system failures on short notice, No-heat and no-cool calls, Short-notice scheduling, Rapid assessment and repair | Anyone whose system has gone down completely, especially during extreme heat or an unexpected cold snap | We take emergency no-heat and no-cool calls seriously. When the house is already at 90 degrees, a diagnostic call that moves fast matters more than one that is thorough but slow. |
| Swamp-Cooler-to-Refrigerated-AC Conversion | Existing cooler removal, Ductwork compatibility assessment, Refrigerated system sizing and installation, Airflow verification to all rooms | Homeowners ready to move away from evaporative cooling for year-round consistent comfort | Refrigerated AC performs the same whether the air outside is dry or carrying monsoon humidity. That consistency is the main reason Pima County homeowners make the switch. |
| Full System Installation & Replacement | Load calculation and equipment sizing, Removal of existing equipment, Ductwork compatibility assessment, New system startup and testing | Homeowners replacing an aging or failed system, or upgrading to a more efficient configuration | Correct sizing matters more in Pima County's heat than almost anywhere else. An oversized unit short-cycles and leaves humidity behind. An undersized one runs constantly through peak summer. |
| Evaporative (Swamp) Cooler Service & Repair | Pad inspection and replacement, Pump and motor service, Water distribution line check, Seasonal startup and shutdown | Homes still running an evaporative cooler that needs to perform reliably through the dry pre-monsoon heat | A well-maintained swamp cooler moves a lot of air efficiently when the humidity is low. Once monsoon season arrives and the air carries more moisture, efficiency drops and that is when most homeowners start weighing their options. |
| Seasonal Maintenance & Tune-Ups | Coil cleaning and inspection, Refrigerant level check, Electrical connection tightening, Filter replacement and airflow check | Homeowners who want to get ahead of problems before the cooling or heating season starts | A spring tune-up before Marana's heat season is the most valuable maintenance call on the calendar. A system that sat idle all winter and gets switched on in late April is starting from an unknown baseline. |
