We've handled everything from a quick tune-up to a full system swap, and we do it for every type of property owner in the area. Homeowners, landlords, property managers, and commercial clients all call us for the same reason: they need heating and cooling work done right the first time. Whether you manage a single rental home or a multi-unit building, we bring the same level of care to every job. Residential HVAC. Commercial HVAC. One number for both. Reach out and we'll get it diagnosed today.
Before a small issue turns into a full breakdown, it pays to get a heating problem checked out. If your furnace is blowing cold air, cycling on and off, or not running at all, our technicians will diagnose the problem and get your heat restored. We offer same-day furnace repair when the schedule allows, because a home without heat is not something you want to wait on.
When your air conditioner stops cooling or shuts down in the middle of a Georgia summer, you need someone on it fast. We diagnose and repair AC systems of all types, including refrigerant issues, condenser and compressor problems, and air handler and blower failures. Same-day AC repair is available, so you are not sitting in the heat any longer than necessary. We'll take care of the system from here.
Heat pumps handle both heating and cooling, which makes them a popular choice across Cobb County given Georgia's mild winters. When a heat pump is not heating, not cooling, or switching modes erratically, the diagnosis requires a technician who understands both sides of the system. We service and repair heat pumps year-round and can help you decide whether a repair or replacement makes more sense for your situation.
Ductless mini-splits are a practical solution for room additions, sunrooms, converted garages, and spaces that fall outside a home's existing duct system. We install, service, and repair mini-split systems from a range of manufacturers. If you are looking to add comfort control to a space that your central system does not reach well, a ductless unit is often the most efficient path forward.
When a system has reached the end of its useful life, a full replacement is the right call. We handle equipment sizing, system selection, and installation from start to finish. Code-compliant HVAC work on every job is not optional for us, it is how we operate. We also evaluate existing ductwork as part of any installation so the new system performs the way it should from day one.
A thermostat upgrade is one of the simplest ways to improve comfort and reduce energy waste in a home or commercial space. We install standard replacement thermostats and programmable or smart thermostats that give you better control over your schedule and your energy use. Zoning controls are also available for properties where different areas need different temperature settings.
Leaky or damaged ductwork wastes conditioned air before it ever reaches the rooms you want to heat or cool. If some rooms are consistently too hot or too cold, or if your energy bills seem high relative to your usage, duct issues are often a contributing factor. We inspect, repair, seal, and replace ductwork to restore proper airflow and improve system efficiency throughout the home.
What circulates through your HVAC system circulates through your home or building. We install whole-house air filtration systems and air purifiers that work alongside your existing equipment to reduce dust, allergens, and other airborne particles. For families with allergy concerns or commercial spaces where air quality matters, this is a straightforward improvement with a noticeable impact.
What sets our technicians apart is straightforward: they take the time to do a thorough inspection rather than a surface-level check. A seasonal tune-up covers the components most likely to cause problems if left unaddressed, and catching a small issue in the fall or spring is far less disruptive than dealing with a breakdown in peak season. We stand behind every system we service, and that starts with honest, complete maintenance work.
We know schedules shift, so we keep your booking flexible, and when a true emergency comes up, we do our best to respond the same day. No heat in the middle of winter and no cooling during a Georgia heat stretch are both situations that cannot wait for a regular appointment slot. Call (470) 995-9879 and let us know what is happening. Call and we'll get your heat or AC back on.
Kennesaw sits squarely in Georgia's four-season climate zone, where summer heat and humidity push cooling systems hard for months at a time and winter cold snaps still require reliable heating. Cobb County homeowners and businesses deal with both ends of the calendar, which shapes the equipment decisions that come up most often around here. The services below reflect what this climate actually demands.
Georgia's high cooling load means air conditioning equipment works harder and longer than it does in cooler climates, which shortens the effective life of older systems. When a furnace or central AC reaches the point where repairs no longer make economic sense, a full system replacement is the practical move. We size the new equipment to your home or building, walk you through the options, evaluate your existing ductwork, and complete the installation to code. A properly sized, correctly installed system runs more efficiently and lasts longer than one that was just swapped in without that groundwork.
Georgia's winters are mild enough that a heat pump can serve as the primary heating-and-cooling system for most homes in the area, handling both functions efficiently without the need for a gas furnace. Heat pump adoption has grown steadily across the region for exactly this reason. We assess your home's load, help you select the right equipment, and pair the installation with a thermostat or smart control that gets the most out of the system.
Kennesaw summers bring sustained humidity that a standard air conditioner manages only partially. An AC removes some moisture as a byproduct of cooling, but it is not designed to control humidity independently. A whole-home dehumidifier integrates directly with your existing HVAC system and maintains target humidity levels throughout the house, improving comfort and indoor air quality at the same time. We handle the installation and set the system to the humidity range that works for your home.
Our primary service area is Kennesaw and the broader Cobb County region. We also regularly serve customers in Marietta, Acworth, Woodstock, Smyrna, Powder Springs, and Canton. If you are in the area and need heating or cooling work done, there is a good chance we have already worked on a system near you. When you call us, you reach the people who actually show up.
Ready to get the comfort back? The reason customers keep calling us is simple: we show up when we say we will, we explain what we find, and we do the work carefully. Our technicians are qualified HVAC professionals who take the job seriously. We protect your floors and finishes while we work, which matters when a technician is moving through a finished home or a commercial space that needs to stay clean. Pricing is straightforward, and we do not push you toward a service you do not need.
A technician will inspect the key components of your system, run diagnostic checks, and identify any problems or developing issues. We explain what we find in plain terms and give you pricing before any repair work begins. The goal is a complete picture of your system's condition, not just a surface-level check.
Common signs include short cycling, uneven heating, unusual sounds like banging or rattling, a system that runs constantly without reaching the set temperature, and higher energy bills without a change in usage. Any of these symptoms is worth a diagnostic call before the problem gets worse.
Short cycling often points to an overheating issue, a faulty flame sensor, or a problem with the control board. Cold air from a furnace can mean an ignition failure, a tripped limit switch, or a clogged filter restricting airflow. A technician can pinpoint the cause quickly once the system is running through a diagnostic cycle.
A general rule is that if a repair costs more than half the value of the system and the equipment is more than ten to fifteen years old, replacement is often the better investment. We lay out both options with honest numbers so you can make the call without pressure.
A whole-home dehumidifier integrates directly with your existing equipment and maintains target humidity levels throughout the house, not just in one room. It handles the moisture load that a standard air conditioner cannot manage on its own, which matters in Kennesaw's humid summers. We install the unit and configure it to the humidity range that works for your home.
A heat pump handles both heating and cooling from a single system, while a standard AC replacement addresses only the cooling side and leaves the heating equipment in place. For homes in Georgia where winters are mild, a heat pump is often the more efficient long-term choice. We assess your home's setup and help you decide which direction makes sense.
Aging systems lose efficiency as components wear, heat exchangers degrade, and refrigerant levels drift. The equipment runs longer to achieve the same result, which shows up on your utility bill. A tune-up can recover some of that efficiency, but at a certain point, replacement delivers better long-term savings.
If some rooms are consistently hotter or colder than others, or if the system runs constantly without reaching the set temperature, ductwork is often a contributing factor. We inspect both the equipment and the duct system as part of a diagnostic visit so we can identify the actual source of the problem.
A burning smell at the start of the heating season is often dust burning off the heat exchanger and may clear on its own, but a persistent burning odor can indicate an electrical or mechanical issue that needs attention. A musty smell typically points to moisture or mold growth somewhere in the duct system or on the evaporator coil. Either symptom is worth a service call.
Banging often points to a loose or broken component inside the air handler or blower. Squealing can indicate a worn belt or bearing. Rattling may mean debris in the system or a loose panel. These sounds are the system telling you something is wrong before a full failure occurs, and catching them early usually means a simpler repair.
Skipping permits, using undersized equipment, or rushing an installation can lead to inefficient operation, premature equipment failure, and repair costs that pile up over time. We pull the permit when the job requires one, install to code, and size equipment correctly so the system performs the way it should for years, not months.
For most repairs and all installations, yes. Our technicians follow safe shutdown procedures before working on any equipment. You do not need to do anything in advance. We handle the lockout and restore power once the work is complete and the system has been tested.
Dale Parrish Heating & Air Conditioner is ready to help with any heating or cooling need in Kennesaw and across Cobb County. We pull the permit. We install it to code. We stand behind it. Whether you need a same-day repair, a seasonal tune-up, or a full system replacement, the process starts with a phone call. We handle both residential and commercial work, and same-day availability is our goal whenever the schedule allows. Call (470) 995-9879 for a quote or to book a service call today.
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.
