Central Air Conditioning Repair 01

Your air conditioning system can last 10 to 15 years—but a new one can quickly pay for itself by lowering energy bills and eliminating frequent repairs. Choose ENERGY STAR central air equipment for clean, quiet cooling that costs less. High-efficiency AC systems cool the indoors while minimizing energy waste and carbon emissions. Trust the Parrish experts for AC installation in Manassas and maintain high-efficiency HVAC systems for years of steady performance.


You can boost indoor comfort and raise energy efficiency by installing a Wi-Fi thermostat. The latest smart thermostats are simple to program and are linked to intuitive mobile apps that allow remote HVAC access. Parrish Services’ Wi-Fi thermostats put you in the driver’s seat, allowing easy, remote control of heating and AC systems.

Getting home later than planned? Turn up the thermostat for a few hours so you don’t air condition an empty house. Set programs to cool a single zone of your home—or delay whole-house cooling until you return from vacation. Smart and Wi-Fi thermostats allow custom control, remote accessibility and adjustments from any handheld device, anytime. Just download the companion app or log into your thermostat by browser. You’ll love how easy it is to use your new thermostat, and the resulting energy savings makes Wi-Fi thermostats a go-to upgrade for today’s homeowners.

I had a great experience with Parrish, and the head technician, Danny Shoop (the assistant was also very good). We had a number of plumbing issues that needed repair, and the work was completed to our satisfaction. I was impressed by Danny's professionalism, his work ethic, and the suggestions and recommendations he made. I will definitely use Parrish again.

Andre and the other technician did a great job installing the new furnace hot water heater and air conditioner. I appreciated the prep and care taken in my home as they carried out the old and brought in the new furnace and hot water heater.

Brandon did a routine inspection of our HVAC that we knew was reaching its replacement age. He was very professional and honest with his assessment and what needed to be repaired or replaced and why, complete with photos and diagnostics. He made sure I knew all my options and pricing (including cost savings) for the recommended parts and services. Very happy with Brandon’s service and Parrish in general.

My wife, Janice, worked with Alton Wallace to convert our fireplace from gas to electric, and Alton was wonderful! We’d never tackled a project like this before so we had some questions along the way, but Alton was very patient and willing to walk us through step-by-step. He was personable and very knowledgeable. We would definitely recommend Alton to future clients!
