What to do When Your Air Conditioner Fails Suddenly

A sudden AC breakdown can be stressful… but staying calm and taking the right steps can help protect your system and your home. If your AC stops working, blows warm air, or makes loud, unusual noises, follow these steps to minimize damage:

  1. Turn Off Your System: Shutting it down can prevent further electrical or mechanical damage.
  2. Check Basic Causes: Make sure circuit breakers haven’t tripped, and check accessible vents or filters for blockages.
  3. Call Althoff Home Services’ 24/7 Emergency Service: Our licensed technicians are available all day or night, fully equipped to get your AC running as quickly as possible.

Common AC emergencies include refrigerant leaks, frozen coils, electrical failures, and complete system breakdowns. These problems can worsen quickly if left untreated, so professional service is the fastest way to restore comfort and protect your system.

We’re Ready 24/7 for AC Emergencies

Air Conditioning problems don’t follow a 9-to-5 schedule – that’s why Althoff Home Services offers true 24-hour emergency service for Crystal Lake, Hillside, and the surrounding suburbs. Our certified technicians arrive fully prepared to diagnose and repair your system quickly. You’ll receive a clear, upfront quote before any work begins, and all repairs are backed by our 100% satisfaction guarantee.

Extra Tips for While You Wait:

  • Keep your home cool by closing the blinds and limiting heat-generating appliances.
  • Avoid attempting DIY fixes that could make the problem worse.
  • If you notice unusual noises or leaks, document them to help our technician diagnose the issue faster.

When your comfort is on the line, we’re here to restore it – day or night. With expert guidance and professional service just a phone call away, you can feel confident that your AC emergency is in good hands.

Q: Does Althoff provide emergency air conditioning service 24/7?

A: Yes, we offer around-the-clock emergency AC repair and response to restore cooling whenever an unexpected failure occurs.

Q: Will I get a quote before work begins in an AC emergency?

A: Absolutely. You’ll receive a clear, upfront quote before any work starts, even during emergency calls.

Q: What kinds of AC issues qualify as emergencies?

A: Emergencies can include refrigerant leaks, frozen coils, electrical failures, or a complete system breakdown–especially when your home quickly becomes uncomfortable.

Q: What should I do immediately when my AC stops working?

A:Turn off the system to prevent further damage, then call for emergency help. Avoid attempting major repairs yourself, as doing so can worsen the problem.

Q: How quickly can a technician arrive for an AC emergency?

A: Our 24/7 emergency team responds as quickly as possible, prioritizing urgent cases to restore comfort fast.

Q: Can an AC emergency cause damage beyond the system itself?

A: Yes. Prolonged malfunctions can lead to higher energy bills, water leaks, or damage to ductwork. Prompt professional service minimizes these risks.

Q: Is it safe to run a malfunctioning AC until help arrives?

A: It’s generally not recommended. Continuing to run a failing system can worsen electrical or mechanical issues. Turning it off and calling Althoff is the safest course.

Q: Can emergency service include temporary solutions?

A: Yes. If a full repair requires special parts or additional work, our technicians can often provide a temporary solution to restore comfort until the system is fully repaired.

Q: How can I tell if a strange noise or smell is an emergency?

A: Loud grinding, hissing, burning smells, or unusual vibrations can often indicate serious issues. If you notice any of these signs, call our emergency service immediately.

Q: Can I prepare my home to make emergency repairs faster?

A: Yes. If possible, take note of any unusual sounds, smells, or performance issues before your system stops working. Sharing these details with our team can help speed up the diagnosis and repair process.

We are so pleased with the work Victor and Braden did-- professional, friendly, fast, and with great explanations. We could not be happier with their work, as we always are with your company's work. The Daikin unit is working perfectly, keeping our open concept kitchen, family room, music room, and dining room a uniform, warm temperature. THANKS!!!

Althoff has helped us with our boiler system as well as our AC unit. They have repaired old units we had and even installed new ones when we needed. Everyone we worked with was kind, professional, and knowledgeable about the products.
Had difficult bulbs to replace and find they did it a short period of time and the installation was flawless

Matthew was such a pleasure to work with. He explained everything in layperson terms. Which I appreciated because I was extremely stressed out from the whole issue at hand. He gave me several different options to deal with the water damage and diagnose the source of the problem. of the leak. In conclusion, I would and will go to Altoff for all my future plumbing needs.

I recently switched to Altoff Services to do my annual A/C and Heater maintenance. They came this week to do the A/C. they did a thorough job in testing my A/C's cooling efficiency. they tested refrigerant levels.They removed the outside unit's shroud and thoroughly cleaned the unit. This was the first time anyone did that. I was very happy with the work they did.

We use Althoff Home Services for almost all of our HVAC, Plumbing, and Electrical needs. Pros: - It is easy to schedule an appointment with them. If you are a member of their White Glove Club, you get priority scheduling. - They spend time explaining the work they perform and any recommendations they have. - Their pricing is transparent. Everything is quoted and sent via email, so you know what you are paying every time they come to your house. - Their employees do not work on commission, so there are no high-pressure sales tactics unlike some of their competitors. Cons: - Some of their services are a little expensive. I would hire a handyman to do things like re-seat a toilet or replace a faucet in lieu of hiring of one of their professional plumbers. - They charge to come out to your house to give pricing estimates, but will deduct this from your bill should you choose to use them. I highly recommend Althoff’s and their team of professional staff!
