"Cardinal really is first class. As a hospitality employee, this is the kind of service you strive towards. Front office - top shelf. The initial call to see if I'm interested in the tune-up was very professional- I had to sign up! The 30 minute out phone call / text was thorough and very well thought through. A picture of the tech coming in and a brief bio on what he's about made the conversation so much easier and natural. The tech they sent in it's called Javier. What a pleasurable young man. Very polite extremely professional and more important knowledgeable. I truly appreciated his patience and walking me through everything he was doing. at the end of it I felt like I had just received a lesson in HVAC but more important, that I had connected with an individual I hope I'll get the opportunity to do more business with. Stellar person an amazing personality / character. You guys hire(d) well. I learned too that you have programs based in preventative maintenance that would provide much-needed peace of mind to a non-techie person like myself. Javier was sure to walk me through every one of them and ask me to think on it and decide if it's something I may be interested in. I didn't have to think twice. I signed up on the spot. Great service from Javier! The after service call to close out was in line with everything I have seen previous with Cardinal. I was walked through the services I opted to get on the maintenance plan and asked if there was any further questions I may have. It is a really nice close out. Very friendly, understanding I may be fumbling my way through understanding how it may work under certain conditions yet also professional. I felt very well served and assured. This is the second time I have used Cardinal. There is always something to be said about consistency in great service and quality. Amazing work Cardinal.... Nicely done!"

Heating and Air Conditioning questions, answered by experts

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

Yes, you can put an AC unit on the roof of your home or commercial building. For proper installation, you’ll need to ensure the roof surface is flat, it’s accessible for maintenance and cleaning, and an AC installation pro agreed that your home is a candidate for package units. Don’t forget to consider the climate in your area, as homes that experience frequent tropical storms or hurricanes may not benefit from this type of system.
