Don’t Risk a Flooded Basement

Generators and sump pumps are two of the most helpful devices you can have during a storm. If you depend on a sump pump to keep your basement from flooding, unexpected power failures could leave you vulnerable to major property damage. Parrish Services prevents property loss and replacement costs by linking sump pump systems to a dedicated battery backup—or connecting them to standby generators. Contact Parrish Services online for an estimate!

Is Your Generator Is Ready for Action?

Professional generator maintenance helps ensure Generac standby generators and other backup power sources perform reliably at a moment’s notice. Between annual maintenance appointments with our certified technicians, Parrish Services also recommends reviewing and adhering to manufacturer maintenance and warranty instructions laid out in your owner’s manual.

When Parrish technicians arrive for your annual generator checkup, they will perform a checklist of tasks tailored to the make, model and age of your device. Steps may include:

  • Clearing debris from inside & outside casing, intake louvers & exhaust vents.
  • Checking control panel fuses.
  • Cleaning battery terminals, verifying battery strength & testing electrical connections.
  • Checking fuel system assembly, gas pressure & connections.
  • Changing oil, spark plugs & air filters.
  • Testing transfer switch. (While your generator probably self-tests on a weekly basis, transfer switch testing is conducted during annual maintenance.)
  • Checking all wiring for corrosion & pest damage.
  • Verifying generator’s power capacity output.

Customer Reviews

Parrish has the best customers in Northern Virginia, hands down! To learn more about the Parrish Difference or discover the many reasons that so many new customers are now lifetime customers, check out these stories from verified clients.

Based on our first encounters with Parrish Services and the technician, Nizil, we expect to have a good relationship over the long term under our new maintenance service. The scheduling is efficient. Nizil is pleasant and knowledgeable. He identified important additional services that I did not consider to be unnecessary upselling, as was the case with our previous service.

This was my 1st experience w Parrish, and...THEY WERE GREAT! From my intial call, to working w Eric about the job and the estimate, to working w several office folks and dispatch prior to the job, and then to day of, EVERY interaction was really great. Many extra thanks to Eric, and it was HE that really made me want to work w him and Parrish. In 110 degrees in my attic, he addressed my HVAC repair and got me back up and running. 5 STARS here!

Great experience. The Technician, Mariusz Loniewski, was very thorough and did a detailed diagnosis and gave me a bid to repair. The main office quickly follows up to schedule the repair work.

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.
