HVAC Services in McCullom Lake, IL
Comfort for the village wrapped around a natural lake
Service Pro Titans provides heating, cooling, and indoor air quality service throughout McCullom Lake, IL — a McHenry County village that began as a 1920s summer-cottage colony and didn’t incorporate until April 7, 1955, three decades after Chicagoans first came north for lake weekends. The village covers barely a third of a square mile, wrapped almost entirely around its natural, 244-acre namesake lake — there’s effectively no inland home here. From converted cottages to newer builds on the same tight lots, our EPA-certified, background-checked technicians service them all — with upfront, flat-rate pricing on every job.
- Upfront, flat-rate pricing — the quote is the price, guaranteed
- Same-day & emergency service across McCullom Lake and the northwest suburbs

McCullom Lake’s Trusted Heating, Cooling & Indoor Air Quality Specialists
McCullom Lake traces back to the 1920s, when Chicagoans began building summer cottages around the natural lake that gives the village its name; incorporation on April 7, 1955 simply formalized what had already been a lake community for three decades. Nearly every home is a short walk from the water — an original cottage converted for year-round living, or a newer build on the same lot — and that mix is why we treat every furnace and air conditioning job as a custom fit, not a template. Homes without central ductwork — converted cottages, additions, finished lower levels near the shoreline — are often strong candidates for ductless mini-splits.
Living this close to a shallow, 244-acre lake also means real summer humidity, which makes indoor air quality upgrades worth a look for many homeowners here, and it makes routine maintenance the cheapest insurance against a mid-January failure in a home that was originally built for July. Whatever era your system dates to, we keep it ahead of sub-zero winters and muggy lake summers. We serve the neighboring communities too — McHenry, Wonder Lake, Johnsburg, and Ringwood are all minutes away.

A Village Built to Fit a Natural Lake — Not the Other Way Around
McCullom Lake started, like a few of its McHenry County neighbors, as a 1920s summer-cottage colony. But the lake at its center wasn’t built for the purpose — it’s a natural, glacially shaped lake in the same kettle-and-moraine country that produced Moraine Hills State Park a few miles away, unlike neighboring Wonder Lake’s reservoir, which developers created by damming a creek in 1929. At 244 acres and only about four feet deep on average — nine at its deepest — it’s shallow enough that its managers run an aerator through winter to keep fish from suffocating under the ice, the same shallow profile that’s made it a locally loved ice-fishing spot for generations. Roughly 80% of the shoreline is lined with private homes, with Peterson Park and its accessible fishing pier holding a stretch open for everyone.
What makes the village distinct even among lake-named neighbors is scale. Incorporated on April 7, 1955, it covers barely a third of a square mile — one of the smallest municipal footprints in McHenry County — wrapped almost entirely around the water, so there’s effectively no “inland” McCullom Lake home. The population nearly doubled between 1960 and 1990 as summer places were winterized and expanded into year-round houses, and that arc still shapes the work: an older converted cottage may be running a system sized — or ducted — for occasional July use, not a full-time Chicago winter. We size, place, and modernize with that history in mind, at the same upfront, flat-rate price every time.

Sean/shawn came out on a hot day and got the ac working within about an hour. Super friendly guy and taught me a few things. This is now my HVAC of choice and I will recommend

I did an HVAC servicing and clean up last week, David was sent out to do this service. He showed up on time with clear communication and did a great job. I then had issues with my HVAC the next week (which ended up being unrelated to the work he did, it was a building issue) and he came out within a few hours to troubleshoot the issue. Great experience working with Service Pro Titans and David, would recommend using them to anybody exploring their help.

Wonderful team from beginning to end. Jeffrey came out very shortly after my AC broke to help me and my family in a very quick turnaround.
He and his team were highly responsive, professional, courteous and felt like they went above and beyond for us. We can’t thank them enough!!

We had our AC unit breakdown in the middle of the night in 85+ degree weather and the service pro titan team was available to talk and schedule a consultation that same night. We opted to schedule for the following the day and their technician arrived on time and was very professional and knowledgable and did their due diligence before recommending a new unit rather than trying to repair our old one. Even though we were going out of the country, this team worked with us to schedule the new install while we were out and did everything on time and made sure that our home and our pet were not suffering from the heat. Absolutely stress free and amazing experience considering the circumstances. Id recommend them to anyone for sure!

Rob from Service Pro Titans is a real lifesaver and I highly recommend him to anyone who is having issues with their hot water boiler system. When my circulator pump coupler broke and then started having other noise issues last winter, Rob came out the next day and was able to diagnose and solve the problem.
Losing heat during winter was very stressful for me. I am extremely grateful to have called Service Pro and gotten help from Rob.
I really did not understand how a lot of the boiler components operated, either. Rob walked me through how the different parts of the system work, maintenance steps I should take, and other common issues that happen with an old heating system.
Now, I feel much more confident about maintaining my boiler, pump, and addressing warning signs before they turn into big problems. If you are having boiler trouble, or just looking for a tune-up to prevent problems down the line, Rob is definitely who you should call.

The Titans were responsive, effective, and affordable. I had another company come out and simply say “replace AC unit” without any detailed diagnosis. The team at Service Pro Titans patiently waited 20min for my tenant to allow access and kept me up to date every step of the way. I felt the entire time that our goals were aligned and they were able to repair the unit for considerable cost and time savings.

I’ve been using Service Pro Titans for the past few years for regular HVAC maintenance so I called when our furnace stopped working. They came by the next day and diagnosed the broken part, made a clear case for why a new furnace made sense and provided a competitive estimate that held up against two other providers. I appreciate their willingness to go the extra mile. My technician, Daniel, carried a ladder up four sets of stairs so that he could get a good look at my AC and confidently estimate the cost of replacement. The two other providers just hand-waved it.
The actual install experience was a total breeze. They pulled out the old furnace and AC, swapped in the new units, and made sure everything they touched still worked, including my doorbell that happened to have a transformer nearby. Jeffrey had it fully in control the whole time. I feel in safe hands using Service for Titans as my HVAC provider going forward.

I live in an older home with a steam boiler that needed some immediate attention. Rob, the technician from Service Pro Titans arrived that day, inspected, repaired my issue and now it's back to normal. He was very knowledgeable about the steam boiler systems. I would recommend Service Pro Titans for your steam boiler needs.

I highly recommend Service Pro Titans. I had them come to inspect both furnaces in my two unit residential building earlier this month. The technician who came, David, was workman-like, efficient, and polite. He found some issues I need to address and reassured me about some others. I would definitely call them again.

Rob came out late in the day and fixed my old boiler and showed me exactly what he was needed and how to take care of any small issues. He was efficient, prepared and patient. He took care of the shoddy work that was done by unscrupulous repair people earlier in the week. Highly recommend.

We needed a whole home humidifier to help protect our wood floors in the dry winter months, and Service Pro Titans were a pleasure to work with. We were scheduled and installed within a week's time, we are very pleased with our experience and will be back when it's time for a new furnace down the line.

Had our AC system completely replaced after moving in to our new unit. The SPT team was and continues to be responsive, and I have recommended them to several other residents in the building.

It hurts to write this review because I used them for many years and they seemed knowledgeable. I recently had a air conditioner yearly check which they said I was low on freon or whatever gas it is. He said to check for a leak would be 900 because the used some other gas to test for the leak after pumping out the system. I didn't have 900, So he just refilled and said we will check again next year. I thought I was still under warranty since it is only 2 years old, so I called and spoke with the office. I was told again that they can come out and check for a leak for 900 and my warranty only covers parts not labor so I would have to pay 900 to see where the leak is at and then pay for the labor to fix a very young unit.
I called around and other places check for leaks with a sniffer which is included in the $89 or whatever service fee. I then thought back when they did a duct cleaning for me. They were to take before and after pics to show me. I saw one pic of before and after. The cleaning seemed to be an almost too fast process for duct cleaning and instead of taking off the panels of the duct work they made holes in the duct work and plugged them up after. I was never consulted on that. Other companies just unscrewed panels. That wasn't cheap either. Be cautious with them.

I've been using Service Pro Titans for years, I'm on their Comfort Plan. They are true professionals. Every problem I've had over the years, either with my furnace, AC or thermostat, they've known how to solve. Their prices are very fair as well. Every person I've dealt with at Pro Titans was very knowledgeable, polite and clearly explained what they found and what their solution would be before actually doing the work. That I really appreciate. You can't go wrong using Service Pro Titans in my opinion.

I needed emergency AC repair in the middle of a heat wave. I called Service Pro Titans and a technician arrived within three hours of my call. The tech was great; he explained every step of the process and discussed the cost with my landlord over the phone. He fixed the issue quickly, much to my relief. I recommend Service Pro Titans heartily!

From my initial contact with Service Pro Titans for a furnace replacement during the Covid Pandemic until now, each service appointment is thorough and educational. I learn something new every visit. After my first service visit, I was so pleased, I recommended Jeffrey and the company to my condo manager, who passed the recommendation to other owners in the building. I think everyone has been pleased.

I have hired SPT for general maintenance on our heating and cooling system for our small business and also to add more ventilation to our space. They have always been awesome commutators when it comes to scheduling and pricing. I would hands down recommend them for any commercial or residential needs!

First time using Servpro Titans. Had an issue with my AC and phoned the business on a Tuesday. The woman who took my call was kind and very helpful in getting a technician out to my home the following day. The technician arrived within the given time slot and resolved my issue. He was also very kind and knowledgeable. The pricing for the service call was VERY economical as well as parts and installation of new parts. I would recommend Servpro Titans over and over.

Highly knowledgeable and skillful professionals, top quality equipment. They did an expert job with an emergency install to replace my furnace in February. Then the A/C condenser's time was up in May and I got the best team again. Big thanks to Jose 1, Jose 2, and Javier for being great at what they do, and being so considerate and accommodating. They definitely are pro. I've worked with many contractors on 3 properties and this team is tops!

Service Pro Titans did an excellent job replacing an old heat pump in my home. They didn't try to upsell me something more than I needed like some other companies did when I got quotes. They have fair pricing and are honest. The job was tricky; they had the best idea to fix the problem and were able to do all of the work without me needing to use other contractors, like other HVAC companies said I would need to do. They completed the job earlier than expected and also found a rebate to save me money. I look forward to working with Service Pro Titans again the next time I have any heating or cooling needs!

What a great experience! We have had 3 technicians from 3 different companies out over the years to address our 3 coil fan units with terrible results. I wish I found Service Pro Titans sooner. They arrived quickly, immediately diagnosed the issues, made a plan to correct, and followed up flawlessly.
Thank you SPT!!!!

They were great! After our furnace blower motor blew out for the second time in a month, I went with professionals instead of trying to fix myself again.
David the technician was communicative on time and punctual. Besides replacing the motor, he addressed the root cause, and reduced the gas pressure to make a more even temperature differential.
We now have a steady consistent heat, instead of super hot for a bit and then cold again. It no longer sounds like a truck is starting in our basement when the furnace kicks on. Twelve years (TWELVE YEARS!) we lived with the loudest noise in the world waking us up in the middle of the night, and David solved it in a few hours.

We had a very good experience with a recent service visit from Service Pro Titan. They responded to our request for a visit to address an issue involving our boiler. They graciously granted our request for a visit on the same day of our call and quickly came to our home and corrected the issue. The technician was friendly and very professional.

Our furnace died one morning in January. Not good! But David was indeed a reliable and professional technician. He arrived on time, took the time to explain the issues and got our household set up with a regular maintenance schedule- all on the same day that our furnace broke down and with plenty of time to protect our home from an arctic blast. 5 stars.

Exceptional! The service provided by Jeffrey, and his team went above and beyond during the replacement of my heating unit. He ensured I wasn't left without heat, even coming late on a Friday evening before a cold winter weekend, when other companies might have delayed until the next business day. Jeffrey dedicated his personal time to guarantee my comfort, exemplifying outstanding customer service. His prompt attention to any issues and consistent prioritization of my needs as a customer demonstrate his commitment to excellence. Rest assured, with this company, you are in excellent hands!

Service Pro Titans just completed their seasonal inspection of my furnace. The technician was timely, professional, friendly, efficient and gave me clear feedback with pictures on the condition of my heating system. Filters were checked and replaced and system performance evaluated.
I have been far more impressed with Service Pro Titans than I had been with Sears, Geek Squad or independent service providers. I recommend them highly.

Great service to replace thermostats and convector controllers in my old high-rise apartment.
Fiston arrived promptly, was professional and tidy, and explained everything well.
I hope I don't need him again 😁 but if I do need him I will be happy to see him back.
Thanks so much. Five stars.

We would highly recommend working with Service Pro Titans. Our tenant's furnace went out unexpectedly and we called Service Pro Titans based on a Google search/reviews that evening around 8pm and they were able to come out the following day. Their service window was large but we received a call when our technician Jeffrey was 30 mins out and again from Jeffrey himself when he was here confirming our address. Jeffrey was courteous, knowledgeable, and was able to problem solve the situation within minutes. Thankfully he had the part in his vehicle and we had a working furnace within 30 mins of his arrival. We also appreciate that they provide a warranty for the part they replaced. Thank you again Jeffrey and Service Pro Titans!

I have been using Service Pro Titans for over a year now. This company is very professional and they do not try to sell you anything you don't need. They were able to save my air conditioner for a year. It needed replacement, but I wanted to wait until this year. Their prices are very fair and they do great work. Everyone that has been here has been very friendly, as well. I would highly recommend Service Pro Titans.
