Cardinal Heating and Cooling Services

The heating and air conditioning system in your home plays a major role in keeping your space safe and comfortable year-round. During extreme heat waves or intense cold fronts, a functional HVAC system can quickly become a life-saving home appliance.
Even during milder seasons, your heating and air conditioning system performs essential functions, like removing excess humidity from indoor air and managing indoor air quality. When it comes to our HVAC units, it’s safe to say we rely on them on a daily basis. Just like our cars need regular maintenance and check-ups to keep them running smoothly, our HVAC systems require ongoing care if we want to get the most out of them.
A well-maintained heating and air conditioning unit will run more efficiently, require fewer repairs and last much longer than a neglected system. While simple tasks, like replacing air filters, can and should be performed at home on a regular basis, the majority of HVAC maintenance and repairs are best left to skilled, qualified professionals. Cardinal heating and cooling services include residential, commercial and industrial HVAC installations, repairs and Maintenance.

Get Annual HVAC Tune-Ups From Cardinal

Our neighbors in Sterling, Alexandria, Gainesville and the surrounding areas in Northern Virginia can take advantage of our competitive HVAC maintenance plan and flexible financing options to cover a wide range of HVAC needs.
We recommend getting your heating and cooling system serviced by a professional HVAC company twice a year — once in the spring to prepare your air conditioner for the summer ahead, and once in the fall to get your heating system tuned up for those chilly winter months. Our fully trained, licensed and insured HVAC experts will perform a 25-point inspection and clean your unit top-to-bottom, including your outdoor condenser unit and evaporator coils.
A thorough inspection by a pro means any loose or worn parts can be detected and replaced long before causing serious problems, saving homeowners time, money and headaches. Cardinal heating and cooling technicians always have your best interests at heart, and our team works hard to meet your needs and budget with free estimates, transparent, upfront pricing and payment options to help cover any unexpected costs.

HVAC Installations from Cardinal Plumbing, Heating and Air

When your old unit is on the fritz, our team of qualified HVAC experts can help. Heating and air conditioning systems last for an average of 12–15 years. If your current unit is approaching this age and you notice rising utility costs, frequent or expensive repairs and a decrease in cooling efficiency — even after performing HVAC maintenance — it’s time to consider an HVAC replacement.
Our pro team can assess your home, lifestyle and budget and make expert recommendations, such as which type of unit is best suited to your home and needs, and what size unit will work most efficiently in your living space. These are important considerations, as an improperly sized unit may not heat or cool your home evenly or efficiently.
Aside from discomfort and higher utility costs, a unit that is too big or too small for your home will be subject to unnecessary wear and tear, which can greatly decrease its overall lifespan. After helping homeowners select the perfect new, energy-efficient system, the Cardinal heating and cooling team can perform professional HVAC installation before setting up an ongoing maintenance plan.

Cardinal Heating and Cooling Emergency Repairs
