Efficient Heating and Cooling

Job update!
✔️We completed a full Armstrong 97% two stage variable and 13 SEER system which qualified for a factory and Nicor rebate.

✔️During the process we replaced a good amount of the ductwork near the furnace area due to a previous steam humidifier the caused a bunch of corrosion.

✔️Increased the return drop sizing for increased CFM and system longevity, and added one individual sidewall return.

A lot of these solutions have been done to help with overall comfort throughout the home. The customer chose to opt out of any IAQ extra products.

Three simple habits make a real difference. 👇

1. Have the system professionally inspected once a year.

2. Keep the thermostat out of direct sunlight for accurate readings.

3. Don't block return vents — the system needs that air to work.

Comfort you can count on all season. ✅

Many warranties quietly require proof of yearly professional service. 📋 Skip it, and a future claim could be denied — leaving you to cover a repair the warranty should have. A seasonal visit protects both your system and your coverage.
