Dale Parrish Heating & Air Conditioner has been the go-to name for heating and cooling in Kennesaw since 208. That is a long time to be doing one thing, and we have stayed at it because we do it right. We serve homeowners, property managers, and business owners across Cobb County with the full range of residential and commercial HVAC work, from a quick repair on a warm afternoon to a full system replacement before the Georgia heat sets in. When you call us, you reach the people who actually show up. No-pressure estimates, priced up front, so you know exactly what you are getting into before any work begins. Residential HVAC. Commercial HVAC. One number for both.
We've handled everything from a quick tune-up to a full system swap, and the range of work we cover reflects what Kennesaw homes and businesses actually need across all four seasons. On the residential side, that means AC repair and service, furnace and heating repair, heat pump repair and installation, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality and air filtration, and seasonal maintenance tune-ups. When a system goes down and you need someone fast, we offer same-day service options for urgent no-heat and no-cool situations.
Commercial clients get the same depth of service. We work with office buildings, retail spaces, restaurants, and mixed-use properties throughout the area, handling commercial AC repair, commercial heating service, and full commercial HVAC installation and replacement. Whether you manage one property or several, we bring the same attention to every job. We'll take care of the system from here.
Georgia's cooling season is long and unforgiving. From late spring through early fall, air conditioners in Kennesaw run hard, and when one starts struggling, the inside of a home or business gets uncomfortable fast. Before a small issue turns into a full breakdown, it pays to have a technician look at what is going on.
Our AC work covers the full arc of what a system might need. We diagnose and repair refrigerant leaks, address airflow problems and uneven temperatures, clean and service evaporator coils, and inspect condenser and compressor performance. If a unit is aging out, we handle central air replacement and new AC installation as well. Seasonal tune-ups and pre-summer inspections help catch small problems before they become expensive ones.
Every job is approached with code-compliant HVAC work on every job as the baseline, because cutting corners on cooling equipment creates problems down the road. If your AC is not keeping up, blowing warm air, cycling on and off too frequently, or simply not turning on, give us a call and we will figure out what it needs.
Cobb County winters are mild compared to much of the country, but a heating system that fails on a cold January night is still a problem that needs solving. Heat pumps have become the dominant heating technology across the Atlanta metro, and for good reason. They handle both heating and cooling efficiently, and the region's climate suits them well. We repair, install, and maintain heat pump systems for homes and businesses throughout the area, including ductless mini-split systems for spaces where traditional ductwork is not practical.
For homes running gas or electric furnaces, we handle repair and replacement work on both. That includes furnace tune-ups, safety inspections, and carbon monoxide checks that give homeowners confidence heading into the colder months. If a furnace is short cycling, failing to ignite, or producing uneven heat, our technicians will diagnose the cause and walk you through the options before any repair work starts.
Reach out and we'll get it diagnosed today.
A well-functioning HVAC system depends on more than just the equipment at the center of it. Leaky or damaged ductwork can waste a significant portion of conditioned air before it ever reaches the rooms it is meant to serve. We inspect, seal, and repair duct systems to restore airflow and help the rest of the equipment work the way it should.
Thermostat and smart-control installation is another area where a straightforward upgrade can make a real difference. Whether it is a programmable thermostat, a Wi-Fi-enabled smart thermostat, or a full zoning system that lets different parts of a home or building run at different temperatures, we handle the installation and setup from start to finish.
Georgia's humidity also makes indoor air quality a genuine concern. We install whole-home air purifiers, UV air filtration systems, and whole-home dehumidifiers that address the moisture and allergen load that comes with the region's climate. We protect your floors and finishes while we work, so the space looks the same when we leave as it did when we arrived.
What sets our technicians apart is straightforward. The work is performed by qualified HVAC technicians who have seen the full range of residential and commercial systems, old and new, simple and complex. That experience matters when a system is behaving in a way that is not obvious, when a repair requires careful diagnosis rather than a parts swap, or when a replacement needs to be sized and installed correctly the first time.
We have worked on every major equipment type and brand in the area. We stay current on the systems that are being installed today, including variable-speed equipment, smart controls, and high-efficiency heat pumps. That means we can service what is already in a home or business and install what makes sense for it going forward.
When a system goes down completely, waiting a week for a technician is not an option. A house with no heat on a cold night or no cooling during a Georgia summer heat wave is an urgent situation, and we treat it that way. We offer same-day service for no-heat and no-cool emergencies, and we work to get to customers as quickly as the schedule allows.
Common emergency calls include systems that will not turn on, units blowing warm air when they should be cooling, frozen coils, short cycling, and systems producing unusual sounds or smells. Whatever the symptom, the goal is the same: get the system diagnosed, explain what needs to happen, and get it running again. Furnace fixed. AC humming. Home comfortable again.
We know schedules shift, so we keep your booking flexible, and that matters especially for commercial clients who cannot afford extended downtime on a heating or cooling system. We work with property managers, office building owners, retail operators, and restaurant operators throughout Kennesaw and the surrounding area.
Commercial HVAC work requires an understanding of larger and more complex systems than most residential jobs. We handle commercial AC repair and service, commercial heating repair, full commercial HVAC system installation and replacement, and ongoing commercial maintenance agreements. For property managers overseeing multiple units or locations, we can coordinate service across properties to keep things running without requiring a separate call for every issue.
If you manage commercial space in Cobb County and need a reliable HVAC contractor who understands the demands of a business environment, we are set up to help.
Every installation and repair we complete is approached with the same standard: the work has to be done right, and it has to hold up. That means following current codes and installation standards on every job, using quality materials and equipment, and not cutting corners to finish faster. We pull the permit when the job requires one, we install to code, and we stand behind the work after we leave.
If something is not right after a job is complete, we want to know about it. We are not satisfied until the system is working the way it should and the customer is confident in what was done. That is not a formal guarantee or a bond. It is simply how we operate, because our name and our reputation in this community depend on it.
HVAC repair and replacement can feel unpredictable from a cost standpoint, and we understand why customers want to know what they are getting into before work begins. Our process is straightforward: a technician assesses the system, explains what is found, and prices the work before anything starts. There are no surprise fees added after the fact.
That approach applies whether the job is a minor repair or a full system replacement. We stand behind every system we service, and that starts with making sure the customer understands and agrees to the scope and cost before we pick up a tool. Whether you are looking at a repair bill or weighing the cost of a new heat pump installation, we will lay out the numbers clearly and answer questions without any pressure to commit.
What sets our technicians apart is straightforward, but the deeper answer goes back further than any single job. This business has been rooted in Kennesaw for a very long time. Generations of homeowners and business operators in Cobb County have called us when their systems needed attention, and we have built that history one job at a time.
When you call us, you reach the people who actually show up. Not a scheduling center, not an answering service. The same locally owned operation that has been serving this community since the beginning picks up, sets the appointment, and sends a qualified technician to the door. That continuity matters, especially when you need someone you can trust to be honest about what a system needs and what it costs. Call and we'll get your heat or AC back on.
Our team works throughout Kennesaw and reaches the communities around it. If you are in Cobb County or just across the county line, there is a good chance we are already working near you. We regularly serve:
If you are not sure whether we cover your area, the fastest way to find out is to call.
We have been taking care of heating and cooling systems in Kennesaw and across Cobb County since 2008. That history reflects a long record of showing up, doing the work right, and standing behind it. We have built our reputation in this community one job at a time.
The work is performed by qualified HVAC technicians who have experience across the full range of residential and commercial systems. They are not subcontractors pulled in for overflow. They are the people we trust to represent this business at every door they walk through.
We stand for honest work, clear pricing, and showing up when we say we will. We have been doing this in Kennesaw since 2008, and the standard that has kept customers calling us back is simple: do the job right, explain what you find, and do not push work that is not needed.
If a system is not performing the way it should after we complete a job, we want to know. Call us directly and we will come back to assess what is happening. We stand behind every system we service, and that commitment does not end when we pack up and leave.
We protect your floors and finishes while we work, so the space looks the same when we leave as it did when we arrived. HVAC work can involve moving through finished living spaces and mechanical areas, and we take that seriously on every job.
Before we start, we walk you through what we found and what the work involves. If something unexpected comes up mid-job, we stop and explain it before continuing. You are never left guessing about what is happening with your system or what it is going to cost.
We respect your time and do our best to arrive within the scheduled window. If something causes a delay, we communicate it. Showing up when we say we will is a basic part of doing business the right way.
When you call us, you reach the people who actually show up. This is a locally owned business where the people answering the phone are the same people sending a technician to your door. That personal accountability is built into how we operate, not something we add on as a selling point.
We schedule realistically and communicate honestly about timing. If a job runs longer than expected, we let the next customer know rather than rushing through work to stay on schedule. Getting the job done right matters more than moving fast.
Dale Parrish Heating & Air Conditioner is ready when you are. Whether you need a same-day repair, a seasonal tune-up, a new system installation, or just want to know what something is going to cost before you commit, we are here to help. We pull the permit. We install it to code. We stand behind it.
Call (470) 995-9879 to request an estimate or schedule a service visit. No pressure, no surprises, just honest HVAC work from a team that has been doing this in Kennesaw for a very long time.
From a quick AC tune-up to a full system replacement, we cover the complete range of heating and cooling work for Kennesaw homes and businesses. Every job gets the same attention: a thorough diagnosis, upfront pricing before work begins, and qualified HVAC technicians on the job from start to finish. Whether you are dealing with a system that stopped working or planning ahead for a seasonal checkup, the table below shows what we handle and what to expect from each service.
| Service | What the Service Includes | When You Need It | Good to Know |
|---|---|---|---|
| Heat Pump Repair & Service |
| Homes with a heat pump as the primary heating and cooling source | Heat pumps handle both seasons, so a problem in one mode often affects the other; early service avoids a full-season loss of comfort |
| Heat Pump Installation |
| Kennesaw homeowners looking for a single system that handles both heating and cooling efficiently year-round | The local climate is well-suited to heat pumps; mild winters and a long cooling season mean the system earns its keep in every season |
| Ductwork Repair & Sealing |
| Homes where some rooms are harder to heat or cool, or where energy bills have crept up without a clear reason | Leaky ducts can account for a significant share of conditioned air lost before it reaches the living space; sealing them improves comfort and efficiency |
| AC Repair & Service |
| Homeowners or businesses with a central AC that is underperforming or not running | Catching a small refrigerant or airflow problem early usually costs far less than waiting for a full breakdown in peak summer heat |
| Emergency HVAC Service |
| Anyone whose system has gone down completely, especially during extreme heat or cold | We prioritize same-day response for system-down situations because a Georgia summer or a cold winter night does not wait for a regular appointment |
| Indoor Air Quality & Air Filtration |
| Households concerned about allergens, dust, odors, or overall air quality inside the home | Upgrading filtration works alongside your existing system without requiring a full equipment replacement |
| Thermostat & Smart-Control Installation |
| Homeowners who want better temperature control, scheduling flexibility, or remote access from a phone | A smart thermostat upgrade is one of the lower-cost improvements that can meaningfully reduce how hard your system works day to day |
| Whole-Home Dehumidification & Humidity Control |
| Georgia homeowners who feel the air is heavy and damp even when the AC is running | A whole-home dehumidifier addresses moisture throughout the house, not just one room, and reduces strain on the cooling system at the same time |
| Full System Installation & ReplacementMost Popular |
| Homeowners replacing an aging or failing system, or building owners upgrading to a more efficient setup | We pull the permit, install to code, and stand behind the work; replacing both sides of the system at once avoids mismatched equipment problems |
| Furnace & AC System Replacement |
| Homeowners whose furnace and AC are both aging, or whose system has had repeated repairs without lasting results | Replacing both units together means matched equipment, better efficiency, and a longer service life than mixing old and new components |
| Heating & Furnace Repair |
| Any home or building where the heating system has stopped working or is not keeping up | Most furnace failures trace back to a handful of common parts; a diagnostic visit pinpoints the cause before any work is quoted |
| Seasonal Maintenance & Tune-Ups |
| Any homeowner or property manager who wants to avoid emergency calls and keep the system running efficiently year-round | A pre-season tune-up is the most reliable way to catch worn parts and low refrigerant before they cause a breakdown at the worst time |
How do I know if my AC or furnace needs to be replaced rather than repaired?
Age and repair history are the two biggest factors. A system that is more than 15 years old and has needed multiple repairs in recent seasons is usually approaching the point where replacement makes more financial sense than continuing to patch it. We assess the condition of the equipment during the service visit and give you an honest read on whether repair or replacement is the better value for your situation.
Why would a system stop heating or cooling even when it is running?
The most common causes are low refrigerant, a dirty coil, a failed component like an igniter or reversing valve, or an airflow restriction from a clogged filter or blocked duct. The system can run without actually conditioning the air when one of those problems is present. A diagnostic visit identifies the specific cause so the repair addresses the real issue rather than a symptom.
How often should we schedule maintenance and tune-ups?
Once a year for each side of the system is the standard recommendation. An AC tune-up in spring before the cooling season and a furnace or heat pump checkup in fall before the heating season gives you the best chance of catching problems before they turn into emergency calls. Homes with older equipment or heavy year-round use benefit from keeping that schedule consistently.
Transparent Upfront Pricing
We give you the numbers before any work starts. If something additional comes up during the job, we explain it and get your approval before proceeding.
Is HVAC installation and replacement work permitted and inspected?
Yes. We pull the permit and the work is inspected to meet local code requirements. That protects you as the homeowner and ensures the installation is done correctly from a safety and efficiency standpoint. We handle the permit process as part of the job.
What are the signs of a refrigerant or airflow problem?
With a refrigerant issue, you will typically notice the system running longer than usual, ice forming on the coil or refrigerant lines, or the air coming from the vents feeling less cold than it should. An airflow problem often shows up as uneven temperatures between rooms, weak airflow at the registers, or the system cycling on and off more frequently than normal. Either situation is worth a service call before it causes further damage.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures usually point to a ductwork problem, an airflow imbalance, or a room that is not well-served by the existing duct layout. Leaky or disconnected ducts are a common cause, as is a damper that has shifted out of position. In some cases, the issue is with the equipment itself. We diagnose the source and explain what it would take to correct it.
Code-Compliant Work on Every Job
We pull the permit and install to code on every replacement and installation. That protects your home and makes sure the work holds up to inspection.
What does a seasonal tune-up actually cover?
A tune-up is a systematic check of the whole system. On the cooling side, that includes inspecting the condenser and evaporator coil, checking refrigerant levels, testing airflow, cleaning the drain line, and confirming the thermostat and controls are working correctly. On the heating side, we check the heat exchanger, igniter, blower motor, and safety controls. The goal is to catch anything that is worn or out of spec before it causes a breakdown.
Can a dirty filter or coil actually hurt system performance?
A dirty filter restricts airflow, which forces the system to work harder and can cause the evaporator coil to freeze. A dirty coil reduces the system's ability to transfer heat, which means it runs longer and uses more energy to reach the set temperature. Both problems are easy to prevent with regular filter changes and annual maintenance, and both can cause real damage if left unaddressed for too long.
Same-Day and Emergency Availability
For no-heat and no-cool situations, we prioritize same-day response. A system-down call in a Georgia summer or a cold winter night does not wait, and neither do we.
How does whole-home dehumidification help in a Georgia summer?
A standard air conditioner removes some moisture as it cools, but in a climate with Georgia's summer humidity levels, it often cannot keep up. A whole-home dehumidifier works alongside the existing HVAC system to pull excess moisture from the air throughout the house. The result is air that feels more comfortable at a higher thermostat setting, less strain on the cooling equipment, and better overall indoor air quality.
How do estimates and pricing work before a job starts?
We assess the system or the scope of work first, then give you pricing before anything is done. For a repair, that means a technician diagnoses the problem and explains what the fix involves and what it costs. For an installation or replacement, we walk through the options and the numbers before you commit. We do not add fees after the fact, and we do not proceed with additional work without your approval.
What should I expect from an emergency or same-day service call?
When you call for a no-heat or no-cool situation, we ask a few questions to understand what the system is doing, confirm your location, and get a technician scheduled as quickly as the day allows. Our goal is same-day response for genuine system-down situations. When the technician arrives, they get straight to diagnosing the problem and explain the repair options before work begins.
Call (470) 995-9879 and we will talk through what your system needs, give you honest pricing, and get you scheduled as soon as possible.
