F.H. Furr provides residential products and services in the plumbing, heating, air conditioning, and electrical business. They put their customers first and provide them with quality products from trained technicians. F.H. Furr has committed to the highest degree of professional development and training in the industry, to work diligently in exceeding every expectation of the client in need. Based out of Manassas, Va., the company has expanded throughout Northern Va., Rockville, Md., Fredericksburg, and Richmond, Va. Whether you need plumbing, heating, cooling, or electrical repairs or replacements, call on F.H. Furr for "Absolutely The Best" service!

"This company truly is something else, I have yet to encounter a plumbing and HVAC company that is as bad as this one. Never had anyone send over clearly inexperienced technicians, or work so hard to over-sell what the issues are, then not only does not deliver, but destroys the existing functional water heater that had no issues. Furthermore, after the fact, then avoid phone calls and emails by "forwarding to their voicemail receptionist" when you try to remedy their mistake. Terrible experience would be an understatement of this company's service. AVOID AT ALL COST!!!. It started with us calling them to do routine water heater maintenance on a 3 year old brand new house. Their Tech name Samuel, not only did  not do the maintenance on the water heater, but sold us on some BS about needing to replace our sump pump and install a water filter for 5k instead, and also buy a HVAC service package. We trusted him because his boss made it sound like you have to do this, and little did we know"

FAQs for water treatment & purification system repair or service projects in Fairfax, VA

If your water softener is over 10 years old or if repair costs approach the price of a new unit, it might be time to replace it. Most water softeners last between 10 and 15 years. Replacing an aging unit can improve your water quality and help you avoid frequent repair costs. For a newer system with minor issues, repairing may be the best option. Consider the age and condition of your system to decide what's most cost-effective.

Water treatment systems remain dependable for 10 to 20 years with proper maintenance and care. A well-maintained system secures full performance by following a scheduled upkeep plan and professional inspections. Consistent maintenance guarantees continuous water purification, ensuring that the system operates at its peak efficiency and delivers high‑quality water throughout its lifespan.

Faulty water softeners exhibit clear symptoms that signal the need for immediate attention. Noticeable mineral build-up around faucets, discolored water, dry or itchy skin following a shower, and altered laundry texture indicate that the system is underperforming. Recognizing these issues early and addressing them promptly prevents further damage and maintains optimal water quality. Early intervention ensures that your water system continues to operate reliably and efficiently.
