- Answering 24/7
- Georgia-licensed and insured HVAC contractors
- Price before work starts
AC Repair
Warm air from the vents, a silent outdoor unit or water under the attic air handler? A licensed technician finds the failed part, from a weak capacitor to a refrigerant leak, and gives you a price before any work starts. Calls are answered 24/7 across Kennesaw and nearby cities.
AC Repair in KennesawFurnace Repair
Furnace clicking but never lighting, or blowing cold air on a freezing night? A licensed technician traces the ignition sequence, tests igniters, flame sensors and pressure switches, and checks for carbon monoxide risk. You approve a written price before the repair. Nights and weekends included.
Furnace Repair in KennesawAC Installation and Replacement
Planning a new air conditioner or a full system changeout? Licensed contractors size the equipment with a Manual J load calculation, explain SEER2 and the shift to R-454B refrigerant, pull the permit and commission the system properly. You get a written quote before anything is ordered.
AC Installation in KennesawHeat Pump Repair and Installation
Heat pump stuck in defrost, caked in ice or leaning on costly auxiliary heat? A licensed technician tests the reversing valve, defrost board, sensors and refrigerant charge, then explains repair or replacement options in writing. Common in Kennesaw townhomes, rentals and all-electric homes.
Heat Pumps in KennesawHVAC Maintenance
A spring AC tune-up and a fall furnace check catch the weak capacitors, slow drain lines and dirty flame sensors behind most mid-season breakdowns. Licensed Georgia contractors clean, test and measure each system, including attic units in two-story homes, then give you a plain report and a price before any repair.
Maintenance in KennesawDuctwork Repair and Airflow
Hot upstairs bedrooms, weak vents and dusty rooms often trace back to leaky, crushed or disconnected flex duct in a hot attic. Technicians find where the air is going, then seal, insulate, rebalance or replace ductwork, and can add zoning, better filtration or a whole-home dehumidifier for humid Kennesaw summers.
Duct Repair in KennesawEmergency HVAC Repair
No cooling in a heat wave, no heat on a freezing night, water coming through the ceiling or a breaker that keeps tripping. Call any hour: we send the closest available licensed technician, tell you on the phone when to expect them, and make sure you hear the price before any work begins.
24/7 Emergency in KennesawHow Our HVAC Services Fit Together
Think of the seven services as answers to five questions:
- Is something broken? That is a repair. AC repair covers air conditioners that run without cooling, freeze up or leak water. Furnace repair covers gas furnaces that will not ignite, short cycle or blow cold air. Heat pump repair covers the heat pumps common in townhomes and rentals near Kennesaw State University.
- Is the system worn out? When age, an R-22 refrigerant system or repeated breakdowns make repair a poor investment, AC installation and replacement covers properly sized new systems, furnaces and heat pumps.
- Is it working but due for care? HVAC maintenance means a spring AC tune-up and a fall furnace check that catch small problems before they become breakdowns.
- Is the problem comfort, not breakdown? Hot upstairs rooms, weak airflow and dusty rooms usually trace to ducts. Ductwork repair and airflow fixes address leaks, balancing and zoning.
- Is it urgent right now? 24/7 emergency HVAC repair is for no heat on a freezing night, no cooling in a heat wave or water coming through the ceiling.
Which Service Fits Your Symptom?
- AC running but blowing warm air: start with our AC not cooling checklist, then AC repair.
- Furnace will not turn on: try the safe checks in furnace not turning on, then furnace repair.
- Heat pump blowing cool air or iced over: heat pump repair.
- Water at the attic unit or a wet ceiling: turn the system off and call for emergency HVAC repair.
- Upstairs always hotter than downstairs: read why the upstairs is so hot, then see duct repair.
- System 15 to 20 years old and failing again: compare options in repair or replace an old AC.
Safety warning: Gas smell or carbon monoxide alarm: leave the house and call 911 or the gas utility from outside before calling us.
Every service is available in Kennesaw and our nearby service areas.
Also Covered Within These Services
Several jobs that other companies list as separate services are part of the seven pages above. If you need one of these, call (321) 478-0693 and say so:
- Thermostats. Replacing, wiring and setting up thermostats, including heat pump and two-stage setups, is handled on AC repair, heat pump and installation visits.
- Ductless mini-splits. For bonus rooms, finished basements and sunrooms, covered on the AC installation page.
- Indoor air quality. Media filters, whole-home dehumidifiers and UV lights, covered on the ductwork and airflow page.
- Zoning and air balancing. Also part of duct repair, for two-story homes with one system.
- Condensate drains, pumps and float switches. Part of AC repair and every tune-up.
What we do not offer
Duct cleaning, plumbing, electrical work beyond the HVAC circuit, and water heaters are outside our scope. Commercial and light commercial systems depend on the equipment and the contractor's license class, so describe the system when you call and we will tell you plainly whether we can help.
Which Services Kennesaw Homes Need, Season by Season
- March to April: Pollen season. Check filters every few weeks and book a spring AC tune-up before the first hot spell.
- May to September: Cooling season. Most AC repair calls land here: capacitors, attic drain clogs, frozen coils. Long run times also expose duct problems in two-story homes.
- September to October: The best window to replace an aging system, with time to compare written installation quotes before winter.
- November to February: Heating season. Furnace repair and heat pump repair calls rise on the first cold nights and during hard freezes.
- Any time: No heat, no cooling, water through a ceiling or a burning smell is an emergency. Calls are answered 24/7.
HVAC Service Questions
What is the difference between a repair visit and a tune-up?
A repair visit starts with a problem, such as no cooling or a noise, and ends with that problem diagnosed and priced. A tune-up is preventive: the technician cleans and tests a working system so small issues are caught before they cause a breakdown. A tune-up can turn up a part that needs repair, which is priced separately before any work.
Do you install new systems or only repair them?
Both. Licensed contractors handle repairs on existing systems and full replacements of air conditioners, furnaces, heat pumps and air handlers, sized with a load calculation and quoted in writing. See AC installation and replacement.
I do not know which service I need. What should I do?
Call (321) 478-0693 and describe what the system is doing, what you hear or smell, and when it started. The person who answers will route the call, and the technician confirms the cause on site before quoting anything.
