The Greatest Hits of Summer HVAC Failures

Thu, 07 May 2026 18:18:22 GMT

Chicago summers don’t mess around—and neither does your HVAC system when it decides to quit at the worst possible time. If you manage a commercial building, you already know: it’s not if something breaks, it’s when… and usually on the hottest day of the year.

Here are the usual suspects:

1. The “I’m Done” Compressor
Your compressor works harder than anyone in July. When it overheats, your building goes from “comfortable office” to “indoor sauna” real fast.

2. Refrigerant Leaks (a.k.a. Slow, Expensive Disasters)
Less cooling, higher bills, and eventually a bigger problem. It’s like your system sweating out money.

3. Electrical Failures
One tiny capacitor goes out… and suddenly the whole system taps out. Not dramatic—just inconveniently catastrophic.

4. Dirty Filters
Clogged filters make your system struggle like it’s breathing through a straw. Easy to fix, expensive to ignore.

5. Thermostat Drama
When controls act up, you get hot spots, cold spots, and confused employees adjusting the thermostat every 10 minutes.

6. Clogged Drain Lines
Humidity builds up, water has nowhere to go, and now you’ve got a leak and an HVAC problem. Bonus

The Bottom Line

Most of these issues are preventable—if you catch them early. If not, they tend to show up during a heatwave… because of course they do.

That’s why Chicago-area businesses rely on Carey’s Heating and Air Conditioning to keep things running smoothly. Regular maintenance now beats explaining to your team why the office or store feels like a greenhouse later. Call Carey’s today at 708-532-2449.

Stay cool out there. Or at least… cooler than ou tside.

How to Choose a Commercial Heating & Air Conditioning Contractor (Without Regretting It Later)

Wed, 29 Apr 2026 18:21:50 GMT

Starting a new business is hard enough—you don’t also need your HVAC system staging a dramatic meltdown on your busiest day. Choosing the right contractor upfront can save you money, headaches, and a few emergency “why is it 85° in here?” moments.

Here’s how to pick a pro (and avoid the pretenders):

1. Make Sure They’re Legit (Yes, This Matters)

Before anything else, confirm they’re licensed, insured, and certified. Ask if their techs are certified through organizations like North American Technician Excellence (NATE).

If they dodge the question or say “we’ve been doing this forever,” that’s not a credential—that’s a red flag.

2. Don’t Hire a “Residential Guy with a Ladder”

Commercial HVAC systems are bigger, more complex, and far less forgiving than residential setups. You want someone who regularly works on:

Rooftop units (RTUs)
Multi-zone systems
Larger ventilation setups

Your café, office, or retail space is not the place for someone’s first “commercial learning experience.”

3. Look for Highly Trained (Union) Technicians

Contractors who employ union labor—like members of Chicago Pipefitters Local 597, Sheet Metal Workers SMART 265, or IBEW Local 134—tend to have rigorous training and ongoing education.

Translation: fewer mistakes, safer work, and less chance your system gets “fixed” twice.

4. Ask About Maintenance Plans (Your Future Self Will Thank You)

A good contractor doesn’t disappear after installation. They’ll offer a maintenance plan to:

Catch small issues early
Keep energy bills from creeping up
Prevent surprise breakdowns

Skipping maintenance is like skipping oil changes—everything’s fine…until it’s really not.

5. Check Reviews…Then Dig Deeper

Online reviews are a good start, but also ask for real business references. Questions to ask:

Do they show up when they say they will?
Do they fix things the first time?
Do they communicate clearly (or vanish like a bad date)?

6. Speed Matters (Especially in July)

When your AC fails during peak summer, it’s not just uncomfortable—it’s bad for business. Look for contractors offering:

24/7 emergency service
Fast response times
Clear communication

Because “we can get there next Tuesday” is not helpful when your customers are sweating through their shirts.

7. They Should Help You Save Money—Not Just Spend It

A strong contractor will recommend energy-efficient solutions, not just the most expensive equipment. Ask about:

High-efficiency upgrades
Smart controls
Rebates and incentives

If every solution somehow costs “top dollar,” you might be funding their vacation home.

8. Demand a Real Proposal (Not a Napkin Estimate)

You want a detailed, professional quote outlining:

Scope of work
Equipment
Timeline
Total cost

If the estimate looks like it was written during lunch with a crayon…keep looking.

9. Safety and Code Compliance Aren’t Optional

Your contractor should follow OSHA standards and local codes. Not only does this protect your business—it keeps you from expensive fines and future problems.

Bottom Line

The right HVAC contractor isn’t just a vendor—they’re a partner in keeping your business running smoothly. Choose someone experienced, responsive, and transparent…so your biggest worry is growing your business—not why your office feels like a sauna.

And remember: in business, surprises are great for birthday parties—not your air conditioning system.

Make Sure Your Business is Ready for the Summer Heat!

Tue, 21 Apr 2026 18:20:48 GMT

After a winter that really showed off (seriously, we get it—snow, wind, repeat), summer is finally around the corner. And while longer days and warmer temps are great for business, they can be… let’s just say less great for an HVAC system that’s been coasting all winter.

If your system isn’t ready, those rising temperatures can turn your workspace into a sauna—and trust us, sweaty employees and uncomfortable customers are not part of anyone’s growth strategy.

That’s where a little Preventive Maintenance (PM) goes a long way.

Think of it like a tune-up for your HVAC system. A little attention now can help you avoid surprise breakdowns, sky-high energy bills, and that one room in your building that’s somehow always 10 degrees hotter than the rest.

At Carey’s Heating and Air Conditioning, we know business owners already juggle enough. Our experienced technicians handle the heavy lifting so your system runs efficiently—and you don’t have to think about it again.

Here’s a quick checklist to get you started:

Change air filters and check belts (the unsung heroes of airflow)
Clear drain pans and condensate lines (because clogs belong in sinks, not HVAC systems)
Check refrigerant levels and recharge if needed
Inspect the compressor
Inspect fan motor blades
Inspect the blower assembly
Inspect and clean the ignition system
Inspect the coil and cabinet, and clean as needed
Inspect the heat exchanger (during heating season)

Bottom line: a well-maintained HVAC system keeps your business running smoothly—and your people happy.

So go ahead, stay cool, keep customers comfortable, and let your HVAC system do its job without drama this summer.

What’s the Best Thermostat Setting for Your Business?

Thu, 02 Apr 2026 18:19:23 GMT

Finding the right thermostat setting isn’t just about comfort—it directly affects your energy bills, equipment lifespan, and the experience you create for both customers and employees.

Here’s how small and mid-sized business owners can think about it.

Balance comfort with cost
Keeping your space comfortable helps employees stay productive and encourages customers to stay longer. But extreme temperature settings can quickly drive up energy costs and put unnecessary strain on your HVAC system.

Adjust based on the season
Workplace guidelines from Occupational Safety and Health Administration suggest a general indoor range of 68–76°F. That said, what feels “right” often depends on the contrast between indoor and outdoor temperatures.

Summer: If it’s very hot outside, blasting the AC too low can feel uncomfortable for customers walking in—and increases costs. A setting around 72–74°F is typically a smart balance.
Winter: Keeping temperatures slightly cooler, around 66–68°F , helps manage heating expenses while maintaining comfort.

Think about the customer experience
A sudden temperature shock—like stepping from 90°F heat into a 65°F store—can actually make customers uncomfortable. Gradual transitions tend to feel better and keep people in your space longer.

Protect your equipment
Moderate thermostat settings reduce wear and tear on your HVAC system, lowering maintenance costs and helping avoid unexpected breakdowns.

Bottom line
For most small and medium-sized businesses, staying near the middle of the recommended range—and adjusting slightly with the seasons—offers the best mix of comfort, cost control, and operational efficiency.
