We are a full-service HVAC contractor, which means we handle the full range of heating and cooling work: repair, installation, replacement, and ongoing maintenance. Whether your system has stopped working or you are planning ahead for a replacement, we have the experience and the technicians to get it done right.
The HVAC work done right the first time is what we are built around. Our core services include:
We work with homeowners, landlords, property managers, and commercial clients. The scope of the job changes, but the standard does not. We'll find the fault and set it right.
Central Florida's heat and humidity put more demand on HVAC equipment than almost anywhere else in the country. The services below are the ones our Apopka customers need most, and they are the ones we have built our day-to-day work around.
In this climate, the air conditioner is not a seasonal appliance. It runs hard for most of the year, and when it stops working, the problem is immediate. Our technicians diagnose the full system on arrival: refrigerant levels, condenser and evaporator coil condition, airflow, and electrical connections to the unit. Whether the system is blowing warm air, short-cycling, or not turning on at all, we identify the cause and explain what it will take to fix it before any work begins.
We handle same-day and emergency calls for no-cool situations, because a broken AC in Apopka in July is not something that can wait until next week. We're one phone call from getting your comfort right.
Heat pumps are the practical choice for Central Florida's mild winters and long cooling seasons. They move heat rather than generate it, which makes them efficient year-round, and they handle both heating and cooling from a single system. We repair, tune up, and replace heat pumps across the area, and we install new systems when an upgrade makes sense.
If your heat pump is not keeping up, running constantly, or blowing air that does not feel right, a qualified technician can diagnose the issue and walk you through the options. We give honest recommendations on repair versus replacement, never an upsell, so you get a straight answer on what the system actually needs.
Florida additions, converted garages, sunrooms, and older homes without existing ductwork all present the same challenge: how do you cool a space that was never set up for central air? Mini-split and ductless systems solve that problem cleanly. They install without ductwork, allow zone-by-zone temperature control, and run efficiently in our climate.
We install, repair, and service mini-split systems for both residential and commercial clients. If you have a space that your central system is not reaching, or a room that runs noticeably hotter than the rest of the home, a ductless system is worth a conversation. Our technicians will assess the space and explain what installation involves before any commitment is made.
Dillon Heating & Cooling was founded in Apopka in 2021. The reason was straightforward: there was a real need for an HVAC company in this area that showed up on time, explained the work clearly, and charged what they said they would charge. That has been the standard from the beginning, and it still is.
The technicians who show up at your door are trained HVAC professionals, not temporary crews or subcontractors pulled in for the season. Being locally owned keeps us accountable to our own community. When something does not go right, there is a real person here to answer for it, and we will make it right. That is not a policy statement. It is how we run the business.
We live here. We keep this area comfortable. We stand behind our work.
We work on homes, rental properties, offices, retail spaces, and restaurants. The equipment and the scale differ, but the core need is the same: reliable comfort, a fast response when something breaks, and pricing that does not surprise you after the fact.
For property managers, we handle multi-unit service calls, scheduled maintenance across a portfolio, and replacement work on aging systems. For business owners, we service commercial equipment and keep systems running through the seasons when downtime is not an option. For homeowners, we cover everything from a single-room mini-split to a full central air replacement.
Every client, residential or commercial, gets the same qualified technicians and the same transparent pricing. Pick up the phone and we'll handle the system.
You shouldn't have to chase a contractor for answers on what the work will cost. Our process is simple: a technician diagnoses the issue, explains what they found, and quotes the job before anything is started. Transparent pricing with no hidden fees on any HVAC job is not a selling point, it is just how honest work gets done.
Pricing varies by system type, age, and the scope of what needs to happen. A refrigerant recharge is a different job than a full system replacement, and we will not give you a number that does not mean anything until someone looks at the actual equipment. Call us for a real quote based on your specific system and situation.
Quick response. Straight pricing. No surprises at the unit.
Comfort problems don't wait, and neither do we, especially when the temperature in Apopka climbs into the nineties and the AC has stopped running. A no-cool situation in Central Florida is a genuine emergency, and we treat it that way.
We offer same-day and emergency service for systems that are down. When you call, we dispatch a technician, they diagnose the problem on arrival, and they quote the repair before touching anything. No guesswork, no surprises. We'll get your home comfortable again fast.
Preventive maintenance is the most cost-effective thing you can do for an HVAC system in this climate. Apopka's heat means the AC runs for most of the year, and equipment that runs hard needs regular attention to stay efficient and avoid unexpected failures.
A seasonal tune-up covers coil cleaning, refrigerant level check, airflow inspection, thermostat calibration, and filter condition. We also check ductwork for leaks and sealing issues during a full system inspection, because leaky ducts quietly reduce efficiency and drive up energy costs without any obvious sign that something is wrong.
The best time to schedule a tune-up in this area is spring, before the peak cooling season arrives. Catching a small problem in April is a lot easier than dealing with a failed system in August. Call to schedule a maintenance visit and we will walk through the full system with you.
Our primary service area is Apopka and the communities throughout Orange County. We also regularly serve the surrounding area, including:
If you are not sure whether we cover your location, give us a call. We will let you know right away.
We have been serving Apopka and the surrounding Orange County communities since 2021. In our fifth year, we work with homeowners, landlords, property managers, and commercial clients across the area. The standard we set at the start, show up on time, explain the work clearly, and charge what we said we would charge, has not changed.
Being locally owned keeps us accountable to our own community. When you call, you reach a real local person who knows the area, and the technicians who show up at your door are trained HVAC professionals, not temporary crews or subcontractors pulled in for the season. We also give honest recommendations on repair versus replacement, never an upsell, which means you get a straight answer on what your system actually needs.
The technicians who handle your job are trained HVAC professionals with hands-on experience on the full range of residential and commercial heating and cooling systems. They are not seasonal workers or outside subcontractors. They show up prepared, treat your property with care, and explain what they are doing throughout the visit.
Our technicians are mindful of floors, walls, and finishes when moving equipment in and out. They clean up after the job and do not leave debris, packaging, or old components behind. The job is not done until the work area is tidy and the system is running correctly.
If a problem returns after we have completed a job, call us. We stand behind our work, and if the issue is related to what we did, we will come back and make it right. We live here and we keep this area comfortable, which means our reputation depends on getting it right, not just getting it done.
Yes. We operate every day from 6:30 AM to 8:00 PM, and we offer after-hours response for urgent situations outside those windows. A no-cool situation in an Apopka summer or a system that stops working entirely is treated as an emergency, and we respond accordingly. Call (321) 241-3235 and we will get someone to you as quickly as possible.
A technician diagnoses the issue, explains what they found, and quotes the job before any work begins. Transparent pricing with no hidden fees on any HVAC job is how we operate. The price you are quoted is the price you pay, with nothing added after the fact.
Yes. Our technicians arrive in well-equipped vehicles stocked for the common repairs and service work we handle every day. Showing up prepared means fewer return trips and faster resolution for you. A professional appearance at the door reflects how we approach the work itself.

Every visit comes with transparent pricing and honest recommendations, so you know what you are getting before any work begins. The table below breaks down what each service covers and who it fits best.
| System Service | Scope of Work | Best For | Things to Know |
|---|---|---|---|
| Emergency HVAC Service | same-day availability, after-hours response, no-cool and no-heat calls, commercial and residential emergency service | any customer whose system has failed and cannot wait for a standard appointment | A failed AC in an Apopka summer is urgent. We come prepared to diagnose and work on the first visit. |
| Full System Installation and ReplacementMost Popular | central system replacement, mini-split and ductless installation, system sizing and equipment selection, installation and post-install testing | homeowners and building owners replacing an aging system or installing HVAC in a new space | When repair costs are climbing or efficiency has dropped significantly, a full replacement is usually the better long-term value. |
| Ductwork Repair and Sealing | duct leak detection, duct sealing and repair, airflow balancing, energy loss assessment | homes with uneven temperatures, high energy bills, or reduced airflow from vents | Leaking ducts can waste a significant portion of conditioned air before it ever reaches the living space. |
| AC Repair and Service | condenser and compressor diagnosis, evaporator coil service, refrigerant leak detection, short-cycle and no-cool troubleshooting | homeowners and property managers with an underperforming or failed central AC | Central Florida's long cooling season puts extra wear on AC components; catching problems early keeps repair costs lower. |
| Heating Repair and Service | heat pump heating diagnosis, air handler and blower service, no-heat troubleshooting, system shutdown diagnosis | any customer whose heating system is down or not performing reliably | Heat pumps are the dominant heating solution in Central Florida; we work on them every day alongside general heating systems. |
| Indoor Air Quality and Air Filtration | air filtration system installation, whole-home air purifier installation, UV air purification units, indoor air quality assessment | households concerned about airborne contaminants, allergens, or air quality in general | In a subtropical climate where homes stay closed and AC runs most of the year, indoor air quality matters more than most people realize. |
| High-Efficiency Central AC Replacement | aging system removal, high-efficiency unit sizing and selection, full installation and testing, energy performance comparison | homeowners with an older, lower-efficiency central AC that runs hard through a long Florida cooling season | An older unit that might last a decade in a cooler climate wears out faster here and costs more to run every month it stays in service. |
| Heat Pump Repair and Installation | heat pump diagnosis and repair, single-unit heating and cooling setup, system sizing for the space, full installation and startup testing | homeowners replacing aging equipment or adding heating and cooling to a space without existing ductwork | Heat pumps are the practical choice in a mild-winter, long-cooling-season climate like Apopka's; one unit handles both functions. |
| Whole-Home Dehumidification and Humidity Control | whole-home dehumidifier installation, integration with existing HVAC system, humidity level configuration, post-install walkthrough | Florida homeowners dealing with persistent moisture, mold risk, or a space that feels warmer than the thermostat reads | A standard AC removes some moisture but was not designed to manage humidity independently; a dedicated unit handles what the AC cannot. |
| Seasonal Maintenance and Tune-Ups | pre-season system inspection, coil and filter check, refrigerant level check, component condition review | homeowners and property managers who want to avoid breakdowns during peak season | A tune-up before the heavy cooling season is the most cost-effective way to catch small problems before they become expensive ones. |
| Thermostat and Smart-Control Installation | programmable thermostat installation, smart thermostat setup and configuration, compatibility check with existing equipment, walkthrough of settings before we leave | homeowners who want better control over comfort and energy use | A smart thermostat upgrade is one of the simplest ways to improve efficiency without replacing the full system. |
How do I know when it is time to replace my AC instead of repairing it again?
A repair makes sense when the system is relatively young, the fault is isolated, and the cost is reasonable compared to what the system has left in it. Replacement becomes the better call when repair costs are climbing, the system is aging past ten to fifteen years, or efficiency has dropped noticeably. We give honest recommendations on repair versus replacement on every visit, so you can make the right call for your home or building without pressure.
Why did my AC stop cooling even though it is running?
A system that runs but does not cool is usually dealing with a refrigerant leak, a dirty evaporator coil, a failing compressor, or a restricted airflow problem. In some cases a clogged filter is the culprit. A technician will work through the system to find the actual fault rather than guessing. We explain what we find before any work starts.
How often should I schedule a tune-up for my HVAC system?
Once a year is the standard recommendation for most systems, and in Central Florida the best time is before the heavy cooling season begins. A pre-season inspection catches worn components, low refrigerant, and dirty coils before they cause a breakdown during the hottest stretch of the year. If you run your system hard year-round, which most Apopka homes do, keeping up with annual maintenance is worth it.
Transparent Upfront Pricing
We explain the cost before any work begins. There are no hidden fees and no surprise charges added after the fact, whether the job is a quick repair or a full system replacement.
What are the signs of a refrigerant or airflow problem?
Common signs of a refrigerant issue include warm air blowing from the vents, ice forming on the indoor coil or refrigerant lines, and the system running longer than usual without reaching the set temperature. Airflow problems show up as weak output from vents, uneven temperatures between rooms, and a system that short-cycles. Both situations call for a technician visit rather than a DIY fix.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures usually point to a ductwork problem, a blocked or undersized vent, or a system that was not sized correctly for the space. In some cases the issue is an aging air handler or a blower that is not moving enough air. We diagnose the cause rather than just adjusting the thermostat, because the fix depends on what is actually causing the imbalance.
What do strange noises from my HVAC unit mean?
A banging or clanking noise often points to a loose or broken component inside the air handler or blower assembly. A high-pitched squealing can indicate a belt or bearing issue. A grinding sound is usually a motor problem. Clicking at startup and shutdown is normal, but clicking that continues while the system runs can signal a relay or control issue. If the noise is new or getting worse, it is worth a call.
Same-Day and Emergency Availability
We offer same-day appointments and after-hours response for urgent situations. A failed AC in an Apopka summer cannot wait, and we treat it that way.
Do I need to be home when the technician arrives?
Someone over eighteen should be present for the visit so the technician can ask about the issue, access the equipment, and walk through the findings with you before any work starts. If you manage a property and cannot be there yourself, a property manager or authorized contact works fine. We confirm the scope and pricing with whoever is on-site before touching anything.
How does your pricing and estimate process work?
When you call, we explain what the visit involves and how pricing is communicated. On arrival, the technician inspects the system and explains what they found before quoting the work. No repairs start until you have a clear picture of what is involved and what it will cost. There are no hidden fees and no charges added after the fact.
Work Performed by Qualified HVAC Technicians
Every job is handled by qualified HVAC technicians who show up prepared, work through the problem systematically, and explain what they find before starting any repairs.
Can a dirty filter or dirty coil actually hurt my system's performance?
Yes, and more than most people expect. A clogged filter restricts airflow to the point where the system has to work harder to move air, which strains the blower motor and can cause the evaporator coil to ice over. A dirty coil reduces the system's ability to transfer heat, which drops efficiency and can lead to compressor problems over time. Changing filters regularly and keeping up with annual maintenance prevents most of these issues.
What does a whole-home dehumidifier do that my AC does not?
A standard air conditioner removes some moisture as a byproduct of cooling, but it was not designed to manage humidity as a primary function. In a subtropical climate like Central Florida's, the AC often cannot keep up, especially on mild days when the system does not run long enough to pull meaningful moisture out of the air. A whole-home dehumidifier integrates with your existing HVAC system and maintains a set humidity level throughout the building regardless of whether the AC is actively cooling.
How long does a full system replacement take?
Most residential system replacements are completed in one day. The timeline depends on the complexity of the installation, whether any ductwork modifications are needed, and the size of the equipment. We give you a realistic estimate of the time involved before the job starts so you can plan accordingly.
Call (321) 241-3235 and we will walk you through your options, give you a straight answer on what the job involves, and get a visit scheduled at a time that works for you.
