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.

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.

Frequently Asked Questions

HVAC maintenance is something that should happen at least twice a year. However, most homeowners neglect their heating and cooling systems. They forget to call for maintenance and even put off repairs until the problem is unavoidable. Unfortunately, delaying your maintenance or repairs causes damage to your system. You also could shorten the life span of your HVAC system. If you want to make your life easier, you can set up an HVAC maintenance plan. You don't need to worry about remembering to call a professional or doing difficult maintenance tasks on your own. Although changing out your filters is something you should do on a regular basis, cleaning coils and lubricating the machinery is something you should leave to the experts. If you work with the right HVAC company, you can trust your system is always in good hands. You take the burden off yourself and improve the functionality of your HVAC.
You can sum up HVAC maintenance in four phases. First, there's the routine tune-up. As you might expect, this phase involves going through and performing a few tasks. A technician might lubricate bearings, check refrigerant levels, and clean off coils. The second phase is the pre-start inspection. After performing the maintenance tasks, the technician checks over their work. They make sure the system is ready to kick on. After turning on the system, your technician will perform operational reviews. This is the phase in which they actively look for problems. If there are issues, they go into the troubleshooting phase. At this time, your technician needs to determine the reason for your HVAC troubles. You might have uneven cooling or strange sounds coming from your vents. A great technician will find out about those issues and address them. After a small repair, you may be able to enjoy an HVAC system that works much better than before.
Believe it or not, the EPA defines major and minor HVAC repairs. A major repair involves doing service, maintenance, or repairs that require the removal of the condenser, evaporator, auxiliary heat exchanger coil, or compressor. Anything else is a minor repair and isn't as serious. For a minor repair, you can expect a quicker and cheaper service. However, you still need an experienced technician. Typically, you need a major repair if the appliances above need to be removed if it has a flaw that can't be fixed. So, you might have extremely rusty coils or another problem that just can't be repaired. In this case, you need a part replacement. The cost of the repair varies, but one fact remains true. You should only trust a reputable HVAC company to handle your repair. Anyone else could do more harm than good and may even damage other components of your heating and cooling system.
