Our certified technicians provide 24/7 heating, cooling, water heater, boiler, heat pump, ductless mini split, and indoor air quality services to Lemont homeowners. Call (224) 253-8131 for same-day service.

Local Lemont HVAC Service from Your Hometown Contractor

Because our service hub is physically in Lemont — not Chicago, not the North Shore — our trucks reach any Lemont address in minutes, not hours. We serve every Lemont neighborhood from the I&M Canal corridor to the homes near Argonne National Laboratory, with full familiarity of the older Lemont housing stock (many homes here run on boilers and have unique heating system configurations) and the newer construction in subdivisions like Kettering, Covington Knolls, and Ruffled Feathers. When your furnace fails on a sub-zero January night or your AC quits during a heat wave, we’re the closest qualified contractor — usually 10 minutes away.

Furnace and Heating Services in Lemont, IL

Lemont winters are unforgiving and the older housing stock — particularly homes built before 1980 — often runs on aging heating equipment that’s overdue for replacement. We service every type of heating system in Lemont:

  • Furnace repair: Same-day service for no-heat emergencies, short cycling, blower issues, ignition problems, and pilot light failures across all major brands
  • Furnace installation and replacement: High-efficiency 95%+ AFUE furnaces sized to your home using Manual J load calculations — not your old equipment’s tonnage
  • Furnace maintenance: Annual tune-ups that catch problems before they become breakdowns and protect manufacturer warranties
  • Boiler repair in Lemont: Many older Lemont homes run on boiler heat — we service every boiler type from cast-iron originals to modern high-efficiency combi units
  • Boiler installation: Upgrades to high-efficiency condensing boilers, including Navien and other premium combi boilers
  • Radiant heat flooring installation: Popular in Lemont’s larger custom homes — we handle full system design and install

Air Conditioning Services in Lemont, IL

When Lemont summers turn humid, your AC is the difference between a comfortable home and a miserable one. Our certified technicians handle every aspect of AC service:

  • AC repair in Lemont: Same-day diagnostic service for systems that aren’t cooling, are blowing warm air, or have failed during a heat advisory
  • AC installation: High-efficiency 16+ SEER systems including variable-speed and two-stage equipment
  • AC maintenance: Spring tune-ups to catch refrigerant leaks, capacitor issues, and coil problems before peak summer demand
  • AC replacement: Honest repair-vs-replace analysis on older systems with upfront written estimates

We install and service AC equipment from every major brand including Trane, Bryant, Carrier, Lennox, Rheem, Goodman, American Standard, Amana, Payne, Ruud, and York. Particularly strong rankings in Lemont for Bryant equipment — we’re the local Bryant specialist for both air conditioner and furnace installations.

Heat Pump and Ductless Mini Split Services in Lemont, IL

Heat pumps are increasingly popular among Lemont homeowners — particularly for additions, finished basements, and as full whole-home replacements paired with backup heating for cold snaps. We offer dedicated service pages for each:

Water Heater Services in Lemont, IL

A failed water heater is one of the most disruptive household problems — no hot showers, no working dishwasher, sometimes water damage in finished basements. We handle tank, tankless, and hybrid water heaters for Lemont homes:

Indoor Air Quality in Lemont, IL

Lemont air quality fluctuates with the seasons — heavy pollen and humidity in summer, dry forced-air heating in winter, and trapped indoor pollutants year-round in tightly sealed modern homes. Our IAQ solutions:

Smart Thermostats and HVAC Duct Services

Round out your system with a smart thermostat (we install Ecobee, Nest, Honeywell T9, and American Standard) and ensure your ductwork is sealed, sized correctly, and free of leaks — duct losses can waste 20-30% of your conditioned air without proper installation and maintenance.

Commercial HVAC in Lemont

We also serve Lemont businesses with full commercial HVAC capabilities including mechanical contracting, rooftop unit installation, commercial boilers, and ventilation systems. See our dedicated Commercial HVAC Lemont page for full details.

HVAC Maintenance Plans for Lemont Homeowners

Our HVAC maintenance plans include two annual visits (spring AC tune-up, fall furnace tune-up), priority scheduling for repair calls, discounted repair rates, and full warranty documentation. The single best way to extend system life and avoid emergency repair costs.

24/7 Emergency HVAC Service in Lemont

Our 24/7 emergency dispatch operates from this Lemont service hub. No-heat winter emergencies and no-cooling summer calls are prioritized for fastest possible response — typically within 30-60 minutes anywhere in Lemont. Call (224) 253-8131 any time, day or night.

Frequently Asked Questions About HVAC Service in Lemont, IL

Common questions Lemont homeowners ask about our local HVAC service — including response times, pricing, brand specialties, older Lemont housing stock, and rebate options.

Yes. Our service hub is physically located at 12766 Marian Drive in Lemont, IL 60439. Unlike contractors operating from Chicago or the North Shore who advertise Lemont service, we're actually here — our trucks dispatch from this location, our parts inventory is stocked here, and our technicians live in and around Lemont. This is why we can typically reach any Lemont address in 10-15 minutes.

For emergency calls (no heat in winter, no cooling during heat advisories, water leaks, gas smell) we typically have a technician at your Lemont home within 30 to 60 minutes. Non-emergency same-day service calls are usually scheduled within 2-4 hours. Our dispatch line is staffed 24/7 — call (224) 253-8131 any time including nights, weekends, and holidays.

We provide complete residential and commercial HVAC service across Lemont including furnace and boiler repair and installation, air conditioning service and replacement, heat pump installation and repair, ductless mini split systems, water heater repair and replacement, indoor air quality solutions, radiant heat flooring, smart thermostats, ductwork, and commercial HVAC services.

Yes — and Lemont has more boiler-heated homes than many surrounding suburbs because of its older housing stock, particularly homes built before 1980 along the I&M Canal corridor and in Old Town Lemont. We service every type of boiler from original cast-iron systems to modern high-efficiency Navien and condensing boilers. Whether you need a quick repair, annual maintenance, or a full replacement, we have local Lemont experience with the heating systems found in these homes.

HVAC repair costs in Lemont typically range from $150 to $450 for common electrical repairs like capacitors and contactors, $400 to $900 for larger repairs like blower motors or circuit boards, and $1,500 to $3,500+ for major repairs like compressors or heat exchangers. Our diagnostic service call is $89 to $150 and is credited toward the repair if you proceed. You always receive a written estimate before any work begins.

Our NATE-certified technicians service every major HVAC brand installed in Lemont homes including Trane, Bryant, Carrier, Lennox, Rheem, Goodman, American Standard, Amana, Mitsubishi, Daikin, Payne, Ruud, York, Navien, and Weil-McLain. We're particularly well-known in Lemont for Bryant furnace and air conditioner service. Common replacement parts for all major brands are stocked on our service trucks.

Lemont homeowners can qualify for ComEd rebates on high-efficiency electric equipment, Nicor Gas rebates on qualifying furnaces and boilers, federal Inflation Reduction Act tax credits on ENERGY STAR–certified heat pumps and high-efficiency HVAC systems, and Illinois Home Energy Rebate Programs for income-qualifying households. We identify all eligible incentives during the in-home estimate and handle the rebate paperwork on your behalf. Current programs are tracked in our HVAC Rebate Center.

Two professional maintenance visits per year — an AC tune-up in spring and a furnace or boiler tune-up in fall. Lemont's extreme seasonal swings from sub-zero winters to 90+ degree summers put unusual stress on HVAC equipment, so preventive maintenance catches small issues before they become breakdowns. Both annual visits, plus priority scheduling and discounted repair rates, are included in our HVAC maintenance plans.

We serve all of Lemont (ZIP 60439) including Old Town Lemont, the McCarthy Road corridor, Equestrian Estates, Briarcliff, Kettering, Covington Knolls, Ruffled Feathers, the I&M Canal corridor, the area near Argonne National Laboratory, and the Heritage Quarries neighborhood. We also serve surrounding communities including Homer Glen, Lockport, Palos Heights, Palos Park, Orland Park, and Willow Springs.

Yes. Eco Temp HVAC offers flexible financing on approved credit for HVAC installations and major repairs. Financing can be combined with available rebates and tax credits to reduce upfront costs and spread payments over time. Many Lemont homeowners use financing for full furnace + AC system replacements or heat pump conversions where upfront cost would otherwise be prohibitive. Ask your comfort specialist during the in-home estimate for current financing plans.

Jordan did a great job servicing my Mitsubishi HVAC system. He showed up on time and he was very thorough. He found a minor problem with the system that previous HVAC companies had not identified and fixed it.. It is difficult finding HVAC companies who are Mitsubishi diamond certified so I will be using them again in the future if my system has any problems.

I recently contacted Jordan with Eco Temp HVAC for a service call to troubleshoot an air handler issue, and I couldn't be more impressed. They responded incredibly quickly, which was a huge help given the situation Jordan was fantastic to work with. He was professional, knowledgeable, and genuinely cared about helping our mutual customer. He went above and beyond the scope of the original service call to make sure everything was taken care of properly. Excellent communication, prompt service, and outstanding customer care. I highly recommend Jordan and the Eco Temp HVAC team. Thanks again for the great service!

I hired another contractor who didn't finish the job properly. I found Eco Temp online and spoke to Jordan who came out the same day. Jordan was not only pleasant and professional; he was very knowledgeable on HVAC and knew right away how to resolve the issues. It's difficult to find someone to work on fan coil units but Jordan was both pleasant and did great work and I would definitely recommend Eco Temp and will call them for future work.

We had an excellent experience with EcoTemp HVAC last Monday. Our boiler was malfunctioning, and they responded the same day we called. Jordan, our technician, went above and beyond by stopping on his way home to make sure we weren’t left without heat. He was extremely knowledgeable about Navien boilers, quickly identified the issue, and fixed it efficiently. Professional, courteous, and clearly well versed in his work. We truly appreciate the exceptional service and wouldn't hesitate to recommend them to anyone needing boiler service— especially Navien systems.

We had a completely new unit installed. Eco Temp HVAC had a competitive price, and the price quoted was the price we paid. No change orders or hidden costs. Very fast and efficient (but careful) installation. They made me feel comfortable that they knew what they were doing and they weren't condescending about it at all. We will be returning to Eco Temp for all of our future servicing needs and will be recommending them to all of our friends and family.

Had a good few experiences with these guys over a few weeks time repairing boilers and also installing a new one. I found them to be very communicative from appointment to arrival to completion and with providing options. Both front desk and staff were in ongoing communication. They did a good job with the installation and repairs and were honest with me about what needed to be done. I'm an out of state landlord and they kept me updated every step of the way. I recommend and I will use them again as I have to install a second boiler.

Great experience with Jordan and Eco Temp, I would highly recommend them! We were a brand new customer, but they came out very quickly, did a temporary fix so we had heat, and came back the next day with the new part. Friendly and professional service start to finish. We had originally called another company who said they couldn't get it started, it would take several days to get parts and fix, and there were multiple issues. We were suspicious, so we decided to call Eco Temp, and we are very glad we did!
