I'd recommend Dynasty Heating and Air to anyone needing work done."

Holidays, weekends, overnight. This is the core of how Chris operates. Not a side service.

The Owner

Chris Graham built Dynasty the way he wished other HVAC companies worked.

After more than 20 years in the trade, Chris knew exactly why so many Atlanta homeowners dreaded calling an HVAC company: the bait-and-switch estimates, the revolving door of technicians, the long waits during the worst heat waves and cold snaps.

Dynasty Heating and Air was his answer. One owner, one phone, one quote. Chris personally diagnoses the problem, writes the flat-rate number down, and then honors it. If he can fix it, he fixes it. If you need a new system, he'll tell you why and show you the options.

He picks up on Christmas Eve. He picks up at midnight. He picks up when your landlord's other HVAC guy has stopped answering. Twenty years in, 4.9 stars across 244 reviews is what that kind of consistency earns you.

Chris Graham Owner & Lead Technician
EPA 608 Certified Federally required for refrigerant work. We hold current certification and talk you through R-22 vs. R-410A so you know what's in your system.
Honest Flat Quotes The number Chris writes down is the number you pay. Review quote: "Chris' quote — which he honored without hesitation — was by far the most reasonable."

FAQ

Real HVAC questions. Real answers.

These are the questions Chris actually fields on service calls. Straight from our FAQ page, no fluff added.

What kinds of refrigerants can be used in my home air conditioner?
It depends on the age of your unit. If you have a home air conditioner that was manufactured before January 1, 2010, it probably uses a refrigerant called hydrochlorofluorocarbon (HCFC)-22 (also known as R-22). Manufacturers cannot make new units using HCFC-22, though servicing existing systems remains permitted.
How can I find out what kind of refrigerant my home air conditioner contains?
The refrigerant used in your home air conditioner is typically listed on the unit's nameplate. Check the outdoor condenser, the owner's manual, or contact your service company or manufacturer for clarification.
Can I still purchase a home air conditioner that contains HCFC-22?
As of January 1, 2010, EPA has prohibited the manufacture and installation of new HCFC-22 appliances. You may purchase used window units manufactured pre-2010, but supplies are diminishing.
Are refrigerants available for home air conditioners that do not harm the ozone layer?
Yes, a number of ozone-friendly refrigerants are available and widely used today. The most common alternative is R-410A, available under various trade names like Puron®.
Will I have to stop using HCFC-22 in my home air conditioner?
No. You will not have to stop using HCFC-22, and you will not have to replace existing equipment. However, supplies will become limited and more expensive over time.
I own an HCFC-22 system. How can I minimize its impact on the ozone layer?
Maintain the unit properly. Request that your technician locate and repair leaks rather than simply "topping it off," which reduces both emissions and your long-term operational costs.
How should I select an appropriate HVAC technician?
Work with reputable dealers that employ service technicians who are EPA-certified to handle refrigerants. Verify that the technician holds Section 608 certification and request documentation. Dynasty holds current Section 608 certification. Just ask.
How should I dispose of appliances containing refrigerants?
Contact retailers, municipalities, or private organizations for proper removal services. Do not tamper with an appliance by cutting refrigerant lines or removing compressors before disposal. That releases refrigerant directly into the atmosphere.
