Flat Rate Heating, AC & Plumbing Pricing in Virginia & Maryland

Let Donmar Company Put Our Experience to Use for You

One thing we’ve learned in our 30 years in the HVAC and plumbing industries is that issues don’t often come at convenient times. We don’t want your family to have to suffer if your heater shuts down in the middle of the night, your air conditioner won’t start on a hot Sunday afternoon, or your pipes burst. That’s why we are open seven days a week from 7 a.m. to 10 p.m. to help your home when you need it most.

Request a service when you call our HVAC professionals and plumbers at (703) 457-8676.

A Commitment to Our Customers

Our flat rate pricing system is part of our absolute commitment to customer satisfaction. You don’t need to worry about being hit with mysterious fees and hidden costs because we’ll give you our fixed price at the beginning of the project. Flat rate pricing is great for our technicians as well; since they’re not working under the gun, they can take the time they need to perform their craft. They have the opportunity to analyze every problem and fix it thoroughly.

This leads to:

  • Fewer callbacks
  • Clearer communication
  • Better service for you 

Our Goal is Your Satisfaction

Above all, flat-rate pricing grants peace of mind for all of our customers. There’s no need to watch the clock during a service visit and stare at an open-ended repair bill. Instead, you’ll go in knowing exactly how much the work will cost, and you can rest easy knowing that our technicians are committed to getting the job done the right way.
