Heating Installation & Replacement

At HVAC Unlimited, we offer many heating services, including heat pump and furnace replacements and installations for homes and businesses in McLean, Lorton, Alexandria, and the surrounding areas. Older heaters usually give some kind of warning when they are in need of a repair or replacement, but can you recognize those signals? Some signs you need a new heating system include:

  • Your heater is coming to the end of its life. The average lifespan of a furnace is 15-20 years. If your unit is older than 15 years, you should consider a furnace replacement.
  • Your energy bills keep rising. If your energy bills have been steadily increasing, but your usage has stayed the same, higher fuel prices might not be the culprit. Furnace efficiency can dramatically decline as the unit ages.
  • You need heating repairs more than once a year. Frequent, costly repairs are a sign of more to come. If you’re facing a repair bill of $500 or more, and the unit is more than 10 years old, consider upgrading to a new unit.
  • Your air quality is decreasing. Dry, stale air and excessive amounts of dust, soot, or rust particles are all signs that your furnace has lost its ability to effectively clean and humidify the air in your home.
  • Your family or home is expanding. If you’re adding on a room or increasing the amount of people living in your home, your furnace may have to work harder than before, raising your energy costs.

Heating Repairs

When it comes to your car, would you ignore odd noises or unusual smells?  You should treat your HVAC system with the same care and precaution because ignoring problems can oftentimes lead to more costly repairs or even the need for a complete replacement.

Commercial and residential heating services require professional repair services, no matter the age, brand, or model. At HVAC Unlimited, we’re experienced in diagnosing and fixing many different challenges, including:

  • Lack of proper maintenance
  • Motor malfunctions
  • Cracked heat exchanger
  • Dirty or misaligned pilot light
  • Dirty or clogged air filters
  • Blower fan issues
  • Broken limit control switch

If you’ve noticed any of the above symptoms with your furnace or heat pump, take advantage of our 24-hour heating services in Northern VA and call us today at 703-493-1200!
