Why Homeowners in Northern Virginia Trust Us for Heating Repair


Is it better to repair or replace an inefficient furnace?

It depends on the age, condition, and efficiency of your system. If your furnace is over 15 years old or requires frequent repairs, replacing it with a modern, energy-efficient unit may save you money long term. We can provide an honest assessment and help you decide what’s best for your home.

What should I do if my boiler is leaking?

Turn off the boiler and water supply immediately to prevent further damage, then call Parrish Services. Our technicians will inspect the system, identify the source of the leak, and perform the necessary repairs to ensure safe operation.

Why is my heat pump blowing cold air?

This could be due to a malfunctioning reversing valve, low refrigerant levels, or an issue with the defrost cycle. Our technicians can diagnose the problem and restore your heat pump’s performance efficiently.

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. Andre took the time to answer what overall questions I had and kept me up to date on the installation progress.

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.

Alton conducted a comprehensive inspection of our home's electrical system. He explained issues as he found them, and even made water heater and fire safety recommendations. I was pleased with his ability to communicate issues clearly and provide a quick turnaround for the quotes.

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!
