Whether you're dealing with a malfunctioning unit in the middle of summer or planning a new AC installation, finding the right company is critical. With countless contractors out there, it’s essential to ask the right questions before signing a service agreement. Asking smart questions not only helps you assess technical capabilities but also uncovers how each company treats their customers. Here are 17 important questions to ask before hiring an AC company.

1. Are You Licensed?

Start with the basics. A reputable AC company should be licensed in your state to perform HVAC work. Licensing demonstrates that the company meets local regulations and has passed necessary examinations. Don’t hesitate to request proof—it’s a standard industry practice.

2. How Long Have You Been in Business?

While newer companies may offer solid service, longevity often signals reliability. A company that’s been in business for several years likely has a proven track record and understands how to handle a wide range of issues. Ask how long they’ve served your area and if they’ve dealt with systems similar to yours. Experienced contractors will also be more adept at spotting potential problems early.

3. What Services Do You Offer?

Some AC companies only handle basic repairs and maintenance, while others provide complete services including installation, ductwork, energy audits, and indoor air quality testing. Ask for a clear list of services so you can decide whether they’ll meet both your current and future needs. Having a full-service provider may save you time and stress down the road if you need other HVAC assistance.

4. Can You Provide References or Reviews?

Reputable companies will gladly offer references or direct you to third-party review platforms like Google or Yelp. Look for consistency in reviews—positive trends in customer service, punctuality, and workmanship are good signs. Take special note of how the company responds to negative reviews. A thoughtful, professional reply shows a commitment to customer satisfaction.

5. What Kind of Warranties or Guarantees Do You Offer?

AC repairs and installations can be costly. An AC company that offers warranties or service guarantees provides peace of mind. Ask about both manufacturer warranties on parts and the company’s own labor guarantee. Many reputable companies stand behind their work for at least a year. Make sure to get all warranty details in writing before any work begins.

6. Do You Offer Free Estimates and Upfront Pricing?

A good AC company should be transparent about their pricing. Ask if they provide free written estimates and whether those estimates include labor, parts, and other potential fees. Avoid companies that give vague quotes over the phone or charge for basic diagnostics without clearly stating so upfront. Clear estimates can prevent future disputes and help you compare companies more accurately.

7. How Do You Handle Emergency Calls or After-Hours Services?

HVAC issues don’t always happen during business hours. Ask if the company offers 24/7 emergency services or same-day appointments. Some companies have answering services or on-call technicians, while others may leave you waiting until the next day. If response time is important to you—especially in extreme weather—verify what kind of availability they offer for urgent repairs.

8. Will You Conduct a Home Evaluation Before Installation?

If you're hiring an AC company for a new installation or replacement, a home evaluation is essential. Contractors should assess factors like square footage, insulation, window placement, and ductwork before recommending a system. A company that offers over-the-phone estimates without visiting your home may not be taking your needs seriously. A proper load calculation ensures energy efficiency and comfort.

9. What Financing Options or Discounts Are Available?

HVAC services can be a significant financial investment. Ask if the AC company offers flexible financing, rebates, or seasonal discounts. Some may even partner with local utilities or manufacturers to help you access incentives. Also inquire about special discounts for seniors, veterans, or first responders. A company that helps customers budget their service is often one that cares about long-term relationships, not just one-time transactions.

10. What Brands Do You Work With or Recommend?

Not all HVAC companies are authorized dealers for every brand. Ask which AC brands they work with and why they recommend them. Ideally, the company should offer a range of brands to match your specific preferences and budget. Technicians should also be comfortable servicing a variety of makes and models, not just the ones they sell.

11. How Do You Handle Permits and Local Codes?

HVAC work often requires permits, especially for new installations or major upgrades. A trustworthy AC company will take responsibility for securing necessary permits and complying with local codes. Ask if the company handles these logistics or expects you to do it yourself. Skipping permits could lead to penalties or problems when selling your home.

12. Do You Offer Maintenance Plans or Service Agreements?

Routine maintenance helps extend the life of your AC system and prevent surprise repairs. In fact, according to Forbes, it's best to schedule professional HVAC maintenance checks annually. Many companies offer service agreements that include seasonal tune-ups, filter changes, and discounts on repairs. Ask about available maintenance plans and whether they’re worth the investment for your specific system and usage.

13. What Is Your Process for Handling Customer Complaints?

Even reputable companies may occasionally run into customer concerns. What matters is how they respond. Ask how they handle complaints or disputes. Do they offer a satisfaction guarantee? Do they have a dedicated customer service representative? A company with a clear, professional conflict resolution process shows integrity and accountability.

14. What Safety Protocols Do You Follow During Service?

Safety should be a priority during any HVAC service. Ask about the AC company’s safety protocols, including protective gear, equipment handling, and COVID-19 or hygiene policies if relevant. Technicians working inside your home should follow clear safety procedures to protect you, your family, and themselves from injury or contamination.

15. How Do You Handle Clean-Up After the Job?

Once the work is done, will the area be left clean and debris-free? Some companies include clean-up as part of their service, while others may leave packaging, dust, or removed parts behind. Ask if they remove old equipment and whether they’ll return your space to its original condition. This attention to detail often separates good companies from great ones.

16. What Is Your Typical Response Time for Service Calls?

Some issues can’t wait. Ask how quickly the AC company typically responds to service requests—especially during peak seasons. Do they offer same-day service? How do they prioritize emergency calls? A fast, reliable response time is essential when you're dealing with extreme temperatures or a sudden system failure.

17. Will You Provide a Written Contract Before Work Begins?

Always get a written contract before any AC work starts. This document should outline the scope of work, materials used, project timeline, total cost, and warranty details. Ask whether the company will walk you through the terms before you sign. Having everything in writing protects both you and the contractor and avoids confusion later on.
