Robertson Heating and Air has been serving Madison and the surrounding Madison County area since 2017, handling the full range of residential and commercial heating and cooling work. We repair AC systems, service and replace heat pumps, install new HVAC equipment, and respond when a system goes down and you need help fast. Whether you manage a single home or a portfolio of commercial properties, we handle the heating and cooling side from the first call to the finished job. We're a local crew, and we pick up when you call.
One call. One technician. One fair price.
Leave the heating and cooling to us.
Every home's heating and cooling setup tells a different story, and we're set up to handle whatever yours looks like. We service and repair central air conditioners, heat pumps, and mini-split and ductless systems. We install complete HVAC systems from scratch and replace aging equipment with properly sized, efficient units. We also handle thermostat and smart-control installation, ductwork repair and sealing, indoor air quality and air filtration, and seasonal maintenance and tune-ups.
When something breaks, we aim to get there the same day. No-cool calls in summer and no-heat calls in the colder months move to the front of the line. Emergency service is part of how we operate, not an add-on.
We keep pricing transparent with no hidden fees on any HVAC job. You know what the work involves and what it costs before we start.
Choosing the right HVAC fix is easier than it sounds when you have a technician who actually looks at the whole system. We work with homeowners across Madison on everything from a single repair call to a full system replacement. Uneven temperatures, weak airflow, and systems that run constantly without cooling the house are among the most common calls we get. We find the cause and fix it right.
Property managers, office buildings, retail spaces, and restaurants all depend on reliable heating and cooling to keep operations running. We work around your schedule and treat downtime as the real problem it is. All work is performed by qualified HVAC technicians who know commercial equipment and understand what consistent performance means for a business.
Whether it's a one-time repair or a full system replacement, the work we do is shaped by what Madison-area homes and buildings actually need. North Alabama summers are long and humid, winters are mild, and the equipment that performs best here reflects that climate. The three services below come up constantly in this area, and we handle each one well.
Alabama summers bring persistent indoor humidity that a standard air conditioner alone often cannot keep in check. High indoor moisture makes a home feel warmer than it is, strains the HVAC system, and can contribute to air quality problems over time. We install whole-home dehumidifiers integrated directly with your existing HVAC system, not portable plug-in units that handle one room. A visit typically includes an assessment of your current setup, a conversation about your comfort goals, and a clear recommendation for the right equipment. We treat your home and its system the way we would our own, and that starts with getting the sizing right.
Madison's mild winters make heat pumps one of the most practical choices for year-round comfort in this region. A heat pump handles both heating and cooling in a single system, which means you're not running separate equipment for each season. We install new heat pumps, replace systems that have reached the end of their service life, and help homeowners and property managers match the right unit to the size and layout of the building. Qualified HVAC technicians handle every installation, from equipment selection through the final system check.
A long Alabama cooling season means an aging central AC system that runs inefficiently costs real money every month it stays in service. If your system is more than 12 to 15 years old, or if it struggles to keep up on the hottest days, a replacement often makes more financial sense than another repair. We start with a full assessment of your current equipment and your home's cooling load, remove the old system properly, and install a right-sized high-efficiency unit built for the demands of this climate.
Call us and we'll handle the rest.
Getting your comfort problem handled starts with a quick call. When an AC stops working in the middle of a Madison summer, or a heat pump fails on a cold January night, waiting days for a technician is not an option. We dispatch quickly, aim for same-day availability on urgent calls, and keep you informed while we're on the way.
We answer the phone. We dispatch the technician. We keep it simple.
No-cool and no-heat calls are the situations we take most seriously. Whether it's a failed compressor, a heat pump that won't switch modes, or a system that simply stopped responding, we show up ready to diagnose and repair. Commercial clients with time-sensitive situations get the same fast response.
Pick up the phone and we'll handle the system.
Choosing the right HVAC fix is easier than it sounds when the pricing is laid out clearly from the start. Before any work begins, we walk through what the job involves and what it will cost. That applies to repair calls and to full installation or replacement projects. No surprises on the invoice, no fees that appear after the fact.
Transparent pricing with no hidden fees on any HVAC job is a standard we hold to on every visit, whether it's a minor repair or a complete system replacement. If you want to know what a job will cost before you commit, call for a quote at (256) 649-2428 and we'll give you a straight answer.
Call and we'll get your heat or AC back on.
A seasonal tune-up is one of the most straightforward ways to extend the life of your HVAC equipment and avoid an unplanned repair. We check refrigerant levels, inspect the blower and airflow, clean the components that accumulate buildup over a season, and verify that the thermostat and controls are reading and responding accurately.
Spring is the right time to service a central AC or heat pump before the cooling season loads up. Fall is when we check the heating side before temperatures drop. A system that gets regular attention runs more efficiently, which shows up in lower utility costs over time, and it's far less likely to fail on the hottest or coldest day of the year.
Well-maintained equipment simply lasts longer. Leave the heating and cooling to us.
Robertson Heating and Air has been locally owned and operating in Madison since 2017. Over those nine years, we've built the business one job at a time, working with homeowners, landlords, property managers, and commercial clients across Madison County. We know the area, we know the climate, and we show up accountable because this is where we work and live.
Our service area covers Madison as the hub and extends to Huntsville, Athens, Harvest, Meridianville, Toney, and the broader Madison County region. Residential or commercial, repair or full installation, we handle the work the same way every time.
We answer the phone. We show up on time. We stand behind the work with a workmanship guarantee on every HVAC job.
We serve Madison as our home base and cover the surrounding communities in Madison County, including Huntsville, Harvest, Meridianville, Toney, Hazel Green, and Athens. If you are not sure whether your address falls within our service area, call (256) 649-2428 and we can confirm quickly.
Yes. When an AC stops working in the middle of a North Alabama summer or a heat pump fails on a cold night, we take those calls seriously and respond as quickly as we can. We offer after-hours and emergency service for genuine no-cool and no-heat situations. Call (256) 649-2428 and we will get a technician headed your way.
First, check your thermostat settings and make sure the system is set to the right mode and temperature. Check your breaker panel for a tripped breaker as well. If neither of those resolves it, call us at (256) 649-2428 and we will treat it as an urgent call and get someone out as quickly as possible.
Warm air blowing from the vents when the AC is running, weak or almost no airflow, a system that turns on and off repeatedly in short cycles, or unusual noises like banging, grinding, or squealing are all signs that something needs attention soon. A burning smell coming from a vent or the unit itself warrants an immediate call. These symptoms tend to get worse the longer they go unaddressed.
It helps to know the general age of your system, the brand if you can find it on the unit, and a brief description of what the system is doing or not doing. If you have noticed the problem getting worse over time or have had any recent repairs done, mention that too. The more we know going in, the faster we can diagnose and get the work done.
For routine maintenance and non-urgent repairs, booking a day or two ahead is usually enough during slower periods. During peak cooling season in the summer, lead times can stretch a bit. For urgent calls, including no-cool and no-heat situations, we aim for same-day availability when our schedule allows.
We serve Madison and the surrounding Madison County area as our primary service zone, so most calls within that range do not carry a separate travel charge. If your location is on the outer edge of our coverage area, call (256) 649-2428 and we will be straightforward about any fees before you commit to anything.
A system that is more than twelve to fifteen years old, requires frequent repairs, or struggles to keep the home comfortable on the hottest or coldest days is often a better candidate for replacement than another repair. We assess the equipment honestly and give you a clear picture of what the repair would cost versus what a replacement would deliver. There is no pressure either way.
We ask that an adult be present for the initial visit so we can access the equipment, discuss what we find, and get your approval before any work begins. If your schedule is complicated, call us and we will do our best to find a window that works. We do not start work without your knowledge and sign-off.
Once we have diagnosed the problem, we walk you through what we found, what we recommend, and what it will cost before any work starts. If something changes once we are into the job, we tell you before we proceed. You will not find out about additional work on the final invoice.

| System Service | What It Covers | Common Needs | Helpful Details |
|---|---|---|---|
| Heat Pump Installation | new heat pump installation, equipment selection and sizing, removal of old system if applicable, final commissioning and controls setup | Homeowners looking for a single system that handles both heating and cooling year-round | Madison's mild winters make heat pumps one of the most practical choices in this region. A properly sized unit handles the full cooling season and the heating load without a separate furnace. |
| Ductwork Repair and Sealing | duct leak detection and sealing, damaged section repair or replacement, airflow balancing, insulation inspection in attic or crawl space runs | Homes with uneven temperatures, high utility bills, or weak airflow in certain rooms | Leaky ductwork can account for a significant share of cooling and heating loss in a home. Sealing ducts is one of the more cost-effective improvements we make. |
| Heat Pump Repair and Service | heating and cooling mode diagnosis, refrigerant and reversing valve checks, defrost cycle and coil inspection, electrical and control component repair | Homeowners with a heat pump that is not heating, not cooling, or short-cycling | Heat pumps handle both seasons in one unit. A system that works in one mode but not the other often points to a reversing valve or refrigerant issue. |
| AC Repair and Service | diagnosis and repair of central AC systems, refrigerant checks and recharge, capacitor, contactor, and electrical component repair, airflow and coil inspection | Homeowners or property managers with a system that is underperforming or not cooling | Most repairs can be completed in a single visit when parts are on hand. Catching small problems early avoids compressor failure later. |
| Full System Installation and ReplacementMost Popular | load calculation and equipment sizing, removal of old equipment, installation of new central AC, heat pump, or furnace, final system check and thermostat setup | Homeowners or property managers replacing an aging or failed system | Systems more than 12 to 15 years old often cost more to keep running than a replacement would. We assess the equipment honestly before recommending either path. |
| Thermostat and Smart-Control Installation | removal of old thermostat, installation of programmable or smart thermostat, wiring and compatibility check, system calibration and walkthrough | Anyone upgrading from a basic thermostat or experiencing inaccurate temperature control | A properly programmed smart thermostat can reduce runtime during unoccupied hours and improve comfort when you are home. |
| High-Efficiency Central AC Replacement | cooling load calculation, removal of old central AC, installation of high-efficiency replacement unit, system startup and performance check | Homeowners with an older or undersized central AC that struggles through the Alabama cooling season | A long cooling season means an inefficient system costs real money every month it stays in service. Replacement often makes more financial sense than repeated repairs on aging equipment. |
| Emergency HVAC Service | same-day response for no-cool and no-heat calls, urgent diagnosis and repair, after-hours availability for genuine emergencies, priority dispatch for system-down situations | Anyone with a system that has completely stopped working, especially in extreme heat or cold | We treat no-cool calls in summer and no-heat calls in winter as the urgent situations they are. Call us and we move those to the front of the line. |
| Indoor Air Quality and Air Filtration | air filtration system installation, UV air purifier installation, media filter upgrades, ventilation and fresh-air assessment | Households concerned about allergens, dust, or air quality inside the home | The filter and filtration setup that came with your system may not be the best match for your household. We assess what you have and recommend upgrades that fit. |
| Seasonal Maintenance and Tune-Ups | refrigerant level check, blower and airflow inspection, coil cleaning, thermostat and controls verification | Any homeowner or property manager who wants to avoid unplanned breakdowns | Spring is the right time to service cooling equipment before the Alabama summer loads up. Fall is when we check the heating side. |
| Whole-Home Dehumidification and Humidity Control | whole-home dehumidifier installation, integration with existing HVAC system, humidity level assessment, equipment sizing for the home | Madison-area homeowners dealing with persistent indoor humidity through the summer months | Alabama summers bring humidity levels that a standard AC often cannot fully address. A whole-home dehumidifier works with your existing system, not around it. |
| Heating and Furnace Repair | furnace diagnosis and repair, heat exchanger and igniter inspection, blower motor and control board service, thermostat and limit switch checks | Anyone who loses heat or notices the system struggling on colder nights | North Alabama winters are mild but real. A furnace that has not been serviced in several years is more likely to fail on the coldest night of the season. |
How do I know if my system should be repaired or replaced?
A system that is more than 12 to 15 years old, needs repairs frequently, or struggles to keep the home comfortable on the hottest days is often a better candidate for replacement than another repair. We assess the equipment honestly and walk you through what a repair would cost versus what a replacement would deliver. There is no pressure either way; we give you the information and let you decide.
What are the signs that my AC or heat pump has a refrigerant or airflow problem?
Warm air blowing from the vents when the system is running, ice forming on the refrigerant lines or indoor coil, a system that runs constantly without reaching the set temperature, or significantly higher utility bills are all signs worth investigating. Weak airflow from the registers often points to a dirty filter, a blocked coil, or a duct issue. We diagnose the cause before recommending any repair.
Why is one room hotter or colder than the rest of the house?
Uneven temperatures usually come down to one of a few causes: duct leaks or blockages that reduce airflow to certain areas, equipment that was not sized correctly for the home's layout, or a thermostat placement issue that causes the system to read the wrong temperature. We look at the whole system, not just the room with the problem.
Transparent Upfront Pricing
Before any work begins, we walk through what the job involves and what it will cost. No fees appear after the fact, and no work starts without your approval.
How often should I schedule a maintenance tune-up?
Once a year for each side of the system is the standard we recommend. Spring is the right time to service a central AC or heat pump before the cooling season, and fall is when we check the heating side before temperatures drop. A system that gets regular attention runs more efficiently and is far less likely to fail on the hottest or coldest day of the year.
What does a seasonal tune-up actually cover?
We check refrigerant levels, inspect and clean the blower and coil, verify that the thermostat and controls are reading and responding accurately, and look for anything that could turn into a failure mid-season. The goal is to catch small issues before they become expensive ones and to confirm the system is running at the efficiency it was designed for.
What causes a system to short-cycle, meaning it turns on and off repeatedly?
Short-cycling is often caused by an oversized system, a dirty or restricted filter, a low refrigerant charge, or a failing component like a capacitor or pressure switch. It puts extra wear on the compressor and makes the home less comfortable because the system never runs long enough to properly dehumidify the air. We diagnose the root cause rather than just resetting the system.
Work Performed by Qualified HVAC Technicians
Every job, from a single repair call to a full system installation, is handled by qualified HVAC technicians who know the equipment and understand what reliable performance looks like.
Can I attempt any HVAC repairs myself, or should I always call a technician?
Filter changes and basic thermostat adjustments are reasonable for a homeowner to handle. Anything involving refrigerant, electrical components inside the unit, or the mechanical parts of the system is work for a qualified HVAC technician. Attempting those repairs without the right tools and training can make the problem worse and create safety risks.
How does the estimate and pricing process work?
We walk through what the job involves and what it will cost before any work begins. That applies to repair calls and to full installation or replacement projects. Transparent pricing with no hidden fees on any HVAC job is how we operate on every visit. If something changes once we are into the job, we tell you before we proceed.
Same-Day and Emergency Availability
No-cool and no-heat calls move to the front of the line. We dispatch quickly and aim for same-day availability on urgent situations so you are not left waiting through the worst of an Alabama summer or a cold January night.
Do I need to be home when the technician arrives?
We ask that an adult be present for the initial visit so we can access the equipment, discuss what we find, and get your approval before any work begins. If your schedule is complicated, call us and we will do our best to find a window that works. We do not start work without your knowledge and sign-off.
How does whole-home dehumidification differ from a portable dehumidifier?
A whole-home dehumidifier is integrated directly with your existing HVAC system and treats the air throughout the entire house as it circulates. A portable unit handles one room and requires manual emptying. For a home in Madison dealing with Alabama summer humidity, a whole-home system is a more consistent and lower-maintenance solution. We size the equipment to the home, not to a generic spec.
How long does a full system replacement typically take?
Most residential system replacements are completed in a single day. The timeline depends on the complexity of the installation, whether any ductwork needs attention, and equipment availability. We give you a realistic timeframe before the job starts so you can plan accordingly.
Every heating and cooling situation is a little different, and the best way to get a straight answer is to call us at (256) 649-2428 for a quote tailored to your home or building.
