Why It Matters
Alexandria winters are not mild. Temperatures regularly drop into the low 20s and teens from December through February with ice storms that push your heating system hard for weeks at a time. A new heating system installed correctly will handle all of that reliably for 15 to 20 years. One installed carelessly will cost you in repairs, high energy bills and premature replacement inside a decade.
The problems usually start at installation. An oversized furnace heats the space too quickly then shuts off before completing a full cycle. This short cycling creates uneven temperatures, excessive humidity and wears out the heat exchanger far ahead of schedule. An undersized system runs continuously and still never reaches your target temperature on the coldest days.
Beyond sizing, improper gas line connections, incorrect flue venting and inadequate ductwork are the leading causes of heating system failures in the first three years of operation. Kelvin HVAC follows manufacturer installation specifications on every job so your new system performs exactly as it was built to from the very first day.
What's Included
All Systems Serviced
No matter what type of AC unit your Northern Virginia home uses, our certified technicians have the training and tools to service it properly.
The most common system in Northern Virginia homes. We service all central AC brands including Carrier, Trane, Lennox, Rheem, Bryant, and more. Full tune-up and efficiency optimization.
Mini-splits are increasingly popular in NoVA additions and older homes. We clean the air handlers, check refrigerant, inspect the outdoor compressor unit, and test all zones.
Heat pumps handle both heating and cooling - meaning they work year-round. We recommend bi-annual maintenance in spring and fall for optimal performance and longevity.
Common in commercial properties and some older residential buildings throughout NoVA. We service all-in-one packaged units with the same thoroughness as split systems.
We clean filters and coils, check electrical components, and assess whether your window or portable unit is still running efficiently or approaching the end of its useful life.
Our maintenance plan covers one AC tune-up every spring and one heating tune-up every fall - priority scheduling, discounted repairs, and peace of mind year-round.
