Chicago Heating & Cooling Done Right.
You've Tried Da Rest. Experience the Difference with D's Air & Heating.
Serving homeowners and businesses throughout Chicago and surrounding communities.
Blown-in insulation is one of the most effective ways to improve energy efficiency, reduce heating and cooling costs, and stabilize indoor temperatures throughout Chicago's extreme weather seasons. At D's Air & Heating, we install high-quality blown insulation for attics, walls, crawl spaces, and hard-to-reach areas. Proper insulation helps prevent heat loss in winter, reduces heat gain in summer, and creates a more comfortable home year-round. Whether your home is older, drafty, or experiencing uneven temperatures, blown insulation provides a fast, affordable, and long-lasting solution. Better insulation also reduces the workload on your heating system and cooling system by maintaining a stable thermal envelope.
Our insulation specialists evaluate your current insulation levels, identify air leaks, and determine the correct R-value needed for your home. Blown insulation fills gaps and voids that traditional batt insulation cannot reach, creating a complete thermal barrier. Customers often notice improved comfort, quieter rooms, and lower utility bills immediately after installation. With Chicago's fluctuating climate, proper insulation is essential for maintaining consistent indoor temperatures and reducing strain on your HVAC system. Pairing new insulation with residential duct cleaning maximizes airflow efficiency and delivers the best results for your home's comfort.
We also offer insulation removal, attic air sealing, ventilation improvements, and energy-efficiency upgrades for homes needing more extensive improvements. Contact us to schedule a free insulation evaluation today.

Indoor Air Quality in Chicago — What Homeowners Should Know
Why Indoor Air Quality Matters
The EPA estimates that indoor air is 2–5 times more polluted than outdoor air. Chicago homes — especially older buildings with limited ventilation — accumulate dust, allergens, volatile organic compounds (VOCs), combustion byproducts, and biological contaminants. Modern HVAC systems can address all of these with the right equipment.
Air Filtration — MERV Ratings Explained
MERV (Minimum Efficiency Reporting Value) rates how effectively a filter captures particles. Standard 1-inch filters are MERV 1–4 and capture only large particles. MERV 8 filters capture most dust and pollen. MERV 13 filters capture fine particles including bacteria and smoke. High-efficiency media filters (MERV 13–16) provide hospital-grade filtration without restricting airflow.
Humidity Control
Chicago winters are extremely dry — indoor relative humidity can drop below 20% when it's cold outside. Low humidity causes dry skin, static electricity, wood shrinkage, and increased susceptibility to respiratory infections. A whole-home humidifier connected to your HVAC system maintains 35–45% relative humidity automatically. In summer, a whole-home dehumidifier prevents mold growth and improves comfort.
UV Air Purification
UV-C light systems installed in the air handler kill bacteria, viruses, and mold spores as air passes through. Lennox PureAir and similar systems combine UV-C with activated carbon filtration to address both biological contaminants and chemical pollutants (VOCs, odors). These systems are particularly valuable for households with allergy or asthma sufferers.
