Two Ways to Protect Your Home
Home systems rarely fail all at once. Most problems start small and often go unnoticed until they turn into expensive repairs.
Cardinal’s Nest Protection Plans help you stay ahead of those problems with smart sensors, system alerts, and proactive service designed to keep your HVAC and plumbing systems running smoothly.
Choose the plan that fits your home. Whether your systems are newer or starting to show their age, we’ll help protect your comfort, your budget, and your peace of mind.
How 24/7 Monitoring Works
24/7 system alerts are powered by small smart sensors installed by our technicians near your HVAC and plumbing systems. These sensors monitor conditions like airflow, filter life, and potential water leaks — with no audio or video capability.
If something unusual is detected, you’ll receive an alert so issues can be addressed early, often before a small problem turns into a costly repair.

Answered All My Questions
“James came over today to perform an AC checkup and cleaning based on my maintenance plan. He was super friendly, did a great job, and answered all of my questions. He even removed 2 old bird nests that were unfortunately right above my unit! Everyone I have encountered at Cardinal has been great to work with!“
Amazing and Knowledgeable Techs
“I signed up for their Nest service which includes hvac and plumbing inspection. Every tech I have encountered has been amazing and knowledgeable. Garred, Tyler, Danny, Jhony, Fabian and Angelo took the time to go over the inspection and recommended maintenance and answer all my questions.“
Extremely Understanding and Accomodating
“I could not recommend Cardinal Plumbing more! Angelo was incredible to work with. We had a gate valve and pressure release valve that needed to be repaired immediately, but live in a condo with a shared main water meter. Cardinal was extremely understanding and able to accommodate our schedule to minimize the time that other residents were impacted by our repairs. We also learned a lot about plumbing through Angelo and signed up for their reasonably priced membership plan. We’re grateful that Cardinal was able to get our home back up and running with water!”
Recommend the Nest Membership
“Jonathan is an awesome technician and also a very good individual. Took time to analyze the HVAC’s and thoroughly explained along with the pics, overall very satisfactory. Cardinal plumbing monthly plan is a very good one and I have recommended to many of my friends.“
Very fortunate to have a maintenance plan
“Am very fortunate to have a maintenance plan with Cardinal. They fit me in at very short notice when my furnace stopped working. They diagnosed and resolved the problem quickly. With temperatures expected in the single digits in the next couple days – this was a critical fix. Very grateful for the service and caring staff. Jamie was great – listened to me, went above and beyond to get the unit working.”
