Every home's heating and cooling setup tells a different story, and we are set up to handle all of them. Homeowners, renters, landlords, property managers, and commercial clients all rely on us for AC repair and service, heating repair, heat pump service, full system installation and replacement, seasonal maintenance and tune-ups, and emergency HVAC when something goes wrong at the worst possible time.
We have been doing this work in Madison since 2017, and our approach has stayed consistent: show up on time, diagnose the problem correctly, and fix it right. Every job we complete comes with a workmanship guarantee, because we stand behind the work after we leave. Leave the heating and cooling to us.
Choosing the right HVAC fix is easier than it sounds, and it starts with a thorough diagnosis. When we come out for an AC repair call, we check refrigerant levels and inspect for leaks, examine the condenser and compressor, test the evaporator coil, and troubleshoot airflow and uneven temperatures throughout the home. We also handle AC tune-ups that keep the system running efficiently through Madison's long cooling season.
A well-maintained air conditioner handles the heat better and costs less to run. If your system is struggling, call us and we'll handle the rest.
When the heat stops working, we get there fast. Our heating repair service covers all common heating systems, including heat strips, heat pumps, and gas furnaces. We handle no-heat calls on the same day when our schedule allows, and we offer emergency heating repair when you cannot wait.
We treat heating calls with the same urgency as AC calls. A cold house in January is just as urgent as a hot house in July.
Heat pumps are the workhorse of North Alabama homes. They run year-round, handling both cooling in the summer and heating through the mild winters, which means they log more hours than almost any other system type. We service and repair all major heat pump brands, and our technicians know these systems well.
If your heat pump is short-cycling, losing efficiency, or not keeping up with the temperature, a service call can usually get it sorted out. For homeowners thinking about a new unit, we cover heat pump installation in the local services section below.
Whether it's a repair, a new installation, or a full replacement, we handle mini-split and ductless systems for residential and commercial customers. Ductless AC is a practical solution for additions, sunrooms, garages, and commercial spaces that do not have existing ductwork. We size the system correctly, install it cleanly, and make sure it performs the way it should from day one.
Leaky or poorly balanced ductwork can quietly drive up your energy bill and leave some rooms too hot or too cold. We locate leaks, seal duct connections, balance airflow across the system, and replace damaged duct sections when needed. Good ductwork makes the whole system more efficient, and the results are usually noticeable right away.
A thermostat upgrade is one of the fastest ways to improve comfort and cut energy use. We install standard replacements and smart thermostats that give you precise control from your phone. If you are interested in zoning or comfort-control systems for different areas of the home, we can walk you through the options.
Getting your comfort problem handled starts with a quick call, but indoor air quality is worth thinking about beyond just temperature. Madison's mix of high humidity, pollen, and seasonal allergens makes air filtration a real concern for many households. We install whole-house air filtration systems, air purifiers, and media filters that work with your existing HVAC equipment to clean the air as it circulates.
For humidity specifically, we cover whole-home dehumidification in the local services section below.
A spring AC tune-up before the heat arrives, and a fall heating check before temperatures drop, are the two maintenance visits that keep most systems out of trouble. During a maintenance visit, we inspect the equipment, clean components, check refrigerant, test controls, and flag anything that looks like it could become a problem. Preventive HVAC maintenance extends system life and keeps repair bills smaller over time.
North Alabama sits in a humid subtropical climate zone. Summers are long and hot, humidity is a constant, and winters are mild enough that most homes here never need a heavy-duty heating system. These three services come up regularly in the Madison area for exactly those reasons.
Madison County summers are not just hot, they are wet. High relative humidity makes a properly cooled home feel warmer than it is, strains the air conditioner, and can lead to mold growth and poor air quality if it goes unchecked. A whole-home dehumidifier works alongside your existing HVAC system to pull excess moisture out of the air continuously, not just when the AC is running.
We size and install whole-home dehumidifiers based on your home's square footage, layout, and current system. The result is air that feels more comfortable at a higher thermostat setting, which also saves energy.
Heat pumps are a natural fit for this part of Alabama. Mild winters mean the system rarely has to work hard in heating mode, and efficient cooling performance through a long summer is where a properly sized heat pump earns its keep. One unit handles both seasons, which simplifies maintenance and reduces equipment costs over time.
We handle new heat pump installation and full system replacement, including load calculations and equipment selection to make sure the unit matches the home. We treat your home and its system the way we would our own, which means we take the time to get the sizing right rather than just swapping in whatever is on the truck.
An aging central air system in a Madison home works harder than it should, especially once it passes the ten to fifteen year mark. A high-efficiency replacement brings down monthly energy costs, improves comfort, and eliminates the cycle of repair calls that older equipment tends to generate.
Replacement starts with a load calculation so the new system is sized correctly for the home. From there, we help with equipment selection, handle the full installation with qualified HVAC technicians, and make sure everything is set up and running before we leave. Pick up the phone and we'll handle the system.
For homeowners and renters, we handle everything from a single repair call to a full system replacement. Residential HVAC work is the core of what we do, and we approach every home visit the same way: diagnose it correctly, explain what we found, and fix it right.
For commercial clients, property managers, and landlords, we understand that downtime costs money and tenants do not wait long before calling. We work with office buildings, retail spaces, multi-unit properties, and apartment communities across the area. Whether you manage one rental or a portfolio of properties, we can be your go-to HVAC contractor for repairs, maintenance, and system replacements.
We're a local crew, and we pick up when you call. Call us and we'll handle the rest.
No AC in the middle of an Alabama summer is not just uncomfortable, it is a health concern. No heat on a cold January night needs attention just as fast. We take emergency HVAC calls for both situations, including after-hours, weekend, and urgent same-day requests when the system cannot wait for a scheduled appointment.
One call. One technician. One fair price.
We do not send a salesperson on an emergency call. We send a technician who can diagnose and fix the problem. Call and we'll get your heat or AC back on.
We started this business in Madison in 2017 and have been serving the area for nine years. Our work stays close to home: Madison, Huntsville, Harvest, Meridianville, Hazel Green, Toney, and the surrounding communities in Madison County. We know the neighborhoods, the housing stock, and the climate, and that local knowledge shows up in how we approach every job. We work hard to earn repeat calls and referrals, and we back that up with a workmanship guarantee on every HVAC job we complete.
For genuine no-cool and no-heat emergencies, we aim for same-day response and offer after-hours availability for urgent situations. When you call (256) 649-2428, we assess the urgency and get a technician dispatched as quickly as our schedule allows. Emergency calls move to the front of the line.
Emergency and after-hours calls may carry a different rate than a standard scheduled visit. We will be upfront about any difference in pricing when you call, before we dispatch a technician. Transparent pricing with no hidden fees on any HVAC job applies to emergency work as well.
A system that has stopped working entirely, no cooling during a Madison summer heat, no heat on a cold January night, or a system that is making loud or alarming noises and will not respond to the thermostat are all situations we treat as emergencies. If you are not sure whether your situation qualifies, call us and we will help you decide.
At the outdoor unit, we check the refrigerant charge, inspect the condenser coil for dirt and damage, test the capacitor and contactor, verify that the fan motor is operating correctly, and look for any signs of refrigerant leaks. We also check the electrical connections at the unit and make sure airflow around the cabinet is not restricted.
Inside, we inspect the evaporator coil, check the blower motor and wheel for buildup and proper operation, measure airflow, and verify that the condensate drain is clear. We also test the thermostat response and check the filter. If the coil is frozen or the drain is backed up, we address those before they cause further damage.
A frozen evaporator coil is usually caused by low refrigerant, restricted airflow from a dirty filter or blocked return, or a failing blower motor. When the coil freezes, the system cannot transfer heat properly and cooling performance drops significantly, sometimes to the point where the air handler blows warm air. We diagnose the root cause and correct it, not just thaw the coil and leave.
Our workmanship guarantee on every HVAC job means that if a problem directly related to our repair or installation comes back after we have completed the work, we will return and make it right. It applies to the labor and work we performed. If you have a concern after a job, call (256) 649-2428 and we will get back out promptly.
An aging or failing system has to run longer cycles to reach the thermostat setpoint because its efficiency has dropped. Dirty coils, low refrigerant, a failing capacitor, or worn components all make the system work harder than it should. That extra runtime shows up directly on your utility bill, and it tends to get worse each season the system goes without attention.
If the system is more than twelve to fifteen years old, if the repair cost approaches or exceeds a significant portion of a replacement cost, or if the system has needed multiple repairs in recent seasons, replacement usually makes more financial sense. We give you an honest assessment of both options so you can make a decision that fits your situation and your budget.
A heat pump that short-cycles, struggles to reach the set temperature in either heating or cooling mode, makes grinding or rattling noises, or shows a significant increase in energy use without a change in how it is being used is showing early signs of a problem. Catching these symptoms early usually means a less costly repair than waiting until the system stops working entirely.
Robertson Heating and Air handles the full range of residential and commercial heating and cooling work, from emergency AC repair and heat pump installation to seasonal tune-ups and high-efficiency system replacements. Whatever your system needs, we have the equipment knowledge and the field experience to get it handled correctly.

| 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.
