"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!"

"We hired Hopper to replace a a 19 yo central AC system. They suggested a solution that saved was 14.3% less than ordering new system from the manufacter. And more importantly they had it installed 2 days later. Hooper is a well establised company that has earned its good reputation."

Heating and Air Conditioning questions, answered by experts

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.
