Optional Maintenance Add-Ons
✦

Air Purifier & UV Lamp Maintenance

UV lamps lose germ-killing power long before they burn out, and purifier cells lose efficiency as they load up. Annual service keeps them capturing allergens, bacteria, and odors at full strength.

💧

Humidifier / Dehumidifier Servicing

Chicago winters dry your home out; summers soak it. We replace pads, clean drains, and calibrate controls so your humidity stays in the healthy zone year-round — protecting your family, your wood floors, and your furniture.

🌡️

Smart Thermostat Upgrade

Cut utility bills with intelligent scheduling, control your comfort from your phone, and catch system issues early with smart alerts — professionally installed and configured for your system.

Equipment That Quietly Stops Working Without Care UV lamps lose germicidal power long before they burn out, purifier cells load up and lose efficiency, humidifier pads need annual replacement, and a professionally configured smart thermostat cuts bills with intelligent schedul...

+How often should I replace my HVAC air filter?

Standard 1-inch filters need replacement every 1–3 months; thicker 4–5-inch media filters last 6–12 months. Homes with pets, allergies, smokers, or nearby construction should use the shorter end of each range. A $20 Filter Protects a $10,000 System A clogged filter strangles airflow — freezing coils in summer, overheating furnaces in winter, and raising bills year-round. It is the single cheapest piece of HVAC maintenance and the most commonly neglected. Maintenance plan visits include filter re...

+Is an HVAC maintenance plan worth the money?

For most homeowners, yes. A plan pays for itself through lower utility bills (a tuned system runs 5–15% more efficiently), fewer emergency repairs, longer equipment life, and protected manufacturer warranties that require documented annual service. Three Plans, One Promise All Set’s Maintenance Club offers Essential Comfort, Healthy Home, and Total Comfort Plus — plus add-ons for air purifiers, UV lamps, humidifiers, and smart thermostats. Members also receive priority scheduling when heat waves...

+How often should HVAC systems be maintained or tuned up each year?

HVAC systems should be maintained andor tuned up each year should be tuned up twice a year: cooling service in spring before summer demand, and heating service in fall before the first cold snap. Each visit is season-specific — spring covers coils, refrigerant, condensate drains, and capacitors; fall covers the heat exchanger, burners, ignition, and carbon monoxide safety checks. Heat Pumps and Air Quality Equipment Included Heat pumps run year-round and benefit most from the twice-yearly schedu...

+Does skipping maintenance void an HVAC warranty?

It can. Most manufacturer warranties require proof of regular professional maintenance — and when a major component like a compressor fails, manufacturers can request service records before honoring the claim. A denied compressor claim can cost thousands. Neglect Causes the Failures Warranties Cover Dirty coils overwork compressors, weak capacitors stress motors, clogged drains flood control boards. A maintenance plan keeps both the equipment and the warranty healthy — with documented service re...

+What does a professional HVAC maintenance visit include?

A proper visit is season-specific. Cooling tune-ups cover condenser and evaporator coil cleaning, refrigerant level and leak inspection, condensate drain clearing, electrical and capacitor checks, and airflow calibration. Heating tune-ups cover heat exchanger and carbon monoxide inspection, burner and ignition cleaning, and safety testing. Every Visit Ends With Numbers, Not a Sticker Both visits include filter replacement, thermostat calibration, and efficiency testing — so you see measurable pe...

+Can regular HVAC maintenance lower my energy bills?

Yes — measurably. Dirty coils, low refrigerant charge, clogged filters, and drifting controls force your system to run longer to deliver the same comfort. Professional maintenance typically restores 5–15% efficiency, which shows up directly on your utility bills. Small Losses Compound Every Month Efficiency loss is gradual, so most homeowners never notice until the bills pile up. Seasonal tune-ups catch the drift twice a year and keep the system near factory performance — one reason a maintenanc...
