AC Maintenance & Tune-Ups
Regular maintenance improves efficiency, prevents breakdowns, and extends the life of your air conditioning system. Our tune-ups keep your cooling system running at peak performance.
Ductless Air Conditioning
Ductless mini-split systems offer flexible cooling, excellent efficiency, and quiet operation—ideal for homes without ductwork or for targeted room-by-room comfort.
IAQ
Indoor Air Quality (IAQ) Solutions
Clean indoor air is essential for comfort and health. Smith Mechanical offers professional IAQ products and services to improve your home’s air quality.
Whole-home air purifiers
Pair whole-home air purification with your AC system to remove dust, allergens, odors, and airborne contaminants as air circulates through your home. Installed directly into your HVAC equipment for cleaner, healthier air in every room.
UV Germicidal Lights
Installed inside your AC system, UV germicidal lights neutralize mold, bacteria, and viruses as air passes over the cooling coil — keeping your coil clean, your air fresher, and your system running more efficiently.
Humidifiers & Dehumidifiers
Balanced humidity works hand-in-hand with your AC to keep your home comfortable. Whole-home humidifiers and dehumidifiers ease the load on your cooling system, reduce allergens and moisture problems, and help your AC run more efficiently year-round.
Duct Cleaning & Sealing
Leaky, dusty ducts rob your AC of efficiency and pump contaminants into every room. We clean and seal your ductwork to boost cooling performance, reduce energy bills, and deliver cleaner air throughout your home.

These guys are PROS! On time to every appointment, Zach and his crew did a top shelf job installing my new furnace and rehanging my broken ducting. The price was VERY reasonable, and the finished work is A+! Would recommend to ANYONE looking for honest work for an honest price.
