5 Key Questions to Ask Before Installing Your Air Conditioner

Installing a new air conditioner isn’t something homeowners do often, so it comes as no surprise that many aren’t sure what to ask before getting started. We’ve seen homeowners jump into Air Conditioner Installation projects without fully understanding the equipment, process, or warranties; and unfortunately, that can lead to poor performance, higher energy costs, and unnecessary repairs down the line.

At repairHVACnow, we help homeowners make confident, informed decisions about their cooling systems. Whether you’re replacing an outdated unit or installing AC for the first time, the right questions can mean the difference between years of reliable comfort and a constant headache.

Before you sign a contract or cut a check, here are the five key questions you should always ask before installing your air conditioner answered from an expert’s point of view.

1. Are You Licensed and Insured?

This is the very first question any homeowner should ask. A proper license ensures your installer meets local, state, and federal standards for safety and performance. Insurance protects both you and the contractor if something goes wrong during installation such as electrical damage, refrigerant spills, or injury on site.

At repairHVACnow, background checks focus on technicians who are fully licensed, insured, and certified under EPA Section 608 for safe refrigerant handling. These certifications matter because improper refrigerant management can cause environmental harm and system inefficiency.

It’s a bad sign if your contractor is hesitant to show you proof of insurance or licensing. Always check these credentials before you sign anything.

2. How Long Have You Been in Business?

In this business, experience is everything.Air conditioning systems need to be installed correctly so that the airflow, refrigerant levels, and electrical loads are all in the right places for your home. If you make a mistake here, the system could last for years less time.

Energy Star says that improper AC installation, like sizing it wrong, not letting air flow through it properly, or charging the wrong amount of refrigerant, can make the system work up to 30% less efficiently than systems that are installed correctly. That’s why experienced installers are so important.

Expert technicians approach every AC installation with decades of field experience.In order to keep your system future-ready and in compliance with environmental regulations, technicians receive ongoing training on new energy-efficient technologies, SEER2-rated equipment, and contemporary refrigerants like R-32.

3. Can You Provide References or Reviews?

A reputable HVAC company should have no problem providing customer references, online reviews, or testimonials. These are the best markers of reliable service quality.

Inquire about a few recent installations that are comparable to yours, particularly if you’re replacing an outdated system or moving from a heat pump to central air. Check for comments regarding communication, cleaning, post-installation assistance, and timeliness.

At repairHVACnow, we’re proud to be one of the top choices for homeowners searching for local HVAC company near me. Our testimonials emphasize the most important factors, which are dependability, honesty, and craftsmanship. Additionally, we advise prospective clients to read vetted reviews or even get in touch with previous customers who can attest to the caliber of the work they have received.Trust is the foundation of all we do, and transparency fosters trust.

4. What Is Your Installation Process?

You can clearly see what to expect if you understand your contractor’s process. A professional Air Conditioner Installation Checklist should include:

• Load calculation (Manual J): establishes the exact size of the unit that your house needs. Systems that are too big or too small are uncomfortable and inefficient.
• Ductwork inspection: Ensures your ducts are sealed, balanced, and sized to handle new airflow requirements.
• Refrigerant line testing: Confirms leak-free operation before charging the system.
• Electrical and thermostat calibration: Integrates your new system with home wiring and smart controls.
• System performance testing: Before the final handoff, system performance testing confirms temperature, pressure, and airflow splits.

ASHRAE (2022) states that poor airflow balancing or duct design can lower cooling efficiency by as much as 30%. We never omit these steps because of this.

At repairHVACnow, techs make it a point to follow detailed, step-by-step What to Know Before AC Installation processes. Each installation is tested for safety, airflow, and performance to ensure it operates at factory-rated efficiency from day one.

5. What Kind of Warranty or Maintenance Plan Do You Offer?

Even with expert installation, every system needs ongoing care. A strong warranty protects your investment and ensures you’re covered if parts fail or performance issues arise.

The U.S. Department of Energy reports that routine maintenance can extend HVAC system life and reduce total energy consumption by up to 15% annually. That’s why pairing your installation with a maintenance plan is one of the smartest decisions you can make.

With repairHVACnow, you’ll get labor and parts warranty with your new system, along with optional service agreements that cover seasonal tune-ups, coil cleanings, filter replacements, and priority scheduling. With a maintenance plan, you won’t just save energy, you’ll prevent unexpected breakdowns during peak summer months.

How to Choose the Right Air Conditioner System

It’s important to know your options before selecting an air conditioner. A competent contractor will walk you through system types, efficiency ratings, and comfort features that are appropriate for the design and climate of your house.

Common options include:

• Central air systems. A common choice for larger homes with pre-existing ductwork.
• Ductless mini-splits. Preferred systems for zoned cooling or older homes without ducts.
• Heat pumps. Systems that provide both heating and cooling and offer energy-efficient year-round comfort.

With the help of the resources and guides at repairHVACnow you choose the right capacity, brand, and model by conducting a full home assessment and heat-load analysis. Your home’s insulation and ventilation setup is also evaluated to ensure your system delivers consistent, balanced cooling.

When it comes to Choosing the Right Air Conditioner System, remember: bigger isn’t better, precision is.
