Set the Ambiance With New Lighting & More

It’s not out of the ordinary to encounter inferior or outdated electrical work when you purchase a house. If the electrical system hasn’t been updated in a few decades, it could be a fire hazard. Because no two projects are alike, our team provides custom services to meet your unique electrical needs.

Whether you want upgraded lighting, new outlets, upgraded wiring for a possible home office, or you need to increase your electrical load to handle new appliances, we’ve got you covered. Our team is highly experienced in dealing with the complexities of electrical systems in Sun Prairie homes. Call to get a free estimate from one of our electricians.

Consider a Plumbing Inspection

Your plumbing system is the guts of your house, and problems may not be immediately evident. Keep an eye out for signs that your new home has plumbing issues. Some warning signs include running toilets, noisy and/or leaky pipes and possibly low water pressure.

More severe problems, however, might be issues with old septic tanks or sewer lines. You can count on us at Cardinal Heating & Air Conditioning to inspect your plumbing system and recommend repairs and/or replacements to ensure everything is in top shape.

Enhance the Comfort & Safety of Your New Home with Simple HVAC Upgrades

As a new homeowner, you’ll want to make sure your HVAC system is going to keep your home comfortable year-round without any unexpected issues. You may want to consider getting an HVAC tune-up, replacing your HVAC filter, and cleaning up the duct and dryer vent systems. Replacing an old thermostat with a programmable model can also make a significant difference in your energy bills.

We’d invite you to consider joining our Cardinal Care Club Membership to keep your plumbing, electrical, and HVAC system in top working order. You'll also benefit from lower utility bills and reduced breakdowns. We look forward to helping keep your new home a place you’ll want to spend plenty of time and share with friends and loved ones.
