Professional Heating and Air Conditioning Installation in Rosemont

Putting in a new HVAC unit can be a major purchase, but it’s also often a good investment. Since the average U.S. household spends 50% of their annual utility bills on heating and cooling, getting the most energy-efficient solution is important. At Atticman Heating and Air Conditioning, Insulation, our local HVAC experts can help you find a heating and cooling solution that’s affordable to own and operate.

Our detailed load calculations help us find the right-sized unit for your home, and we can go over the options for the best SEER 2.0 or AFUE rating that’s within your budget. Ductless mini-splits and heat pumps offer the highest ratings but are often more expensive during initial installation. Let us explain the possible savings and do the paperwork to get you the maximum rebates and refunds on your energy-efficient installation.

Complete HVAC Maintenance

From furnace and air conditioning tune-ups to duct sealing, we do it all. In fact, we’re a leader in duct sealing since our target is always less than 1% leakage, while the industry standard is 4%. During a tune-up, we clean your furnace or air conditioner, test all major systems and lubricate any moving parts. When we tell you the system is in good shape, that means there aren’t worn parts or repairs likely to happen over night.

When you need help with your home HVAC system, Atticman Heating and Air Conditioning, Insulation is ready to swoop in and save the day. Our team will give you a full, upfront estimate that’s always reasonable for the work needed.

Reece and Vince were here at 6:30am this morning to install a new system on the hottest day of the summer so far this year. It's 9:15pm. While they have encountered some technical difficulties and have been troubleshooting for the last couple of hours, the install could not be completed. These two demonstrated tenacity in a difficult situation. They were professional in spite of their exhaustion.

Hoping to get the system working tomorrow. 🤞

UPDATE: Fidel arrived this afternoon and after a bit of troubleshooting, we now have AC! Hooray! Bravo, Fidel!

Looking forward to a cool house with a quiet new system.

Began with an estimate for service on HVAC system. Carlos was excellent and informative. Next, Felipe came same day and explained options for system replacement. Purchased new heat pump and AC. Installation team was on time, stayed all day, and did an excellent job installing new equipment. I recommend this company.

Both the technicians that came out were friendly and professional.
Got my AC running again at a great repair price.
Also gave quotes on maintenance and upgrades to my 23 year old r22 system/furnace that is hanging by a thread.
Would highly recommend this company.
Thank you again.

Awesome response. Our AC lost all power over the weekend. I contacted them and they came out the next day. Had the problem fixed within 15 minutes.

I highly recommend Atticman. We had our complete system replace last year.

Great Team. Fabian, Limver, Angel, and Damian who are very professional and hard working. They installed my two brand new 4-ton Trane units without issues. These guys put out their top notch quality work, and am very happy with my AC & Heat Pump units ... no more furnace, no more expensive gas.
Thank you and keep up your best work.
Also thank you to Fidel (supervisor) and all the front office staff who kept me informed during the install.

Logan came out serviced my Air Conditioner today plus educated me on how the system works, and fixed the problem. So thankful that I have cool air and a new air purifier😉

After not having a tune up done in a LONG time, Jaspreet was very professional and friendly, explaining things that I was already aware of - but broken down to where the repairs/cleaning seemed much more do-able and not as daunting in the long run. As it is a business, there will always be a type of upselling (which i get), but there was absolutely no pressure. When finances permit, I will definitely be going through this company and will also recommend it to my cousin who has multiple rentals.

Yikes! 😱😱. Our AC unit stopped working yesterday in this 104 degree heat! The temperature inside was rising fast. I called the AtticMan and Kobe, their technician, was able to come out early this morning and replaced the fuse in a matter of minutes. We are appreciative of his quick response to get our AC up and running so quickly. Thank you , Kobe, for coming out to our home! 🎉🎉.
