Questions to Ask BeforeReplacing Your System

Replacing your air conditioner or heating system is one of the largest investments you will make in your Las Vegas home. The summer heat over 100 degrees Fahrenheit runs your cooling system for months, while cold desert nights require a capable gas furnace or heat pump. Because this equipment handles such extreme conditions, choosing the right replacement matters. Knowing what to ask helps you compare the options.

A thorough contractor welcomes your questions. They want you to understand the condition of your current equipment and the reasoning behind their recommendations.

Why Are You Recommending a Replacement?

A contractor should never recommend a replacement based on age alone. The ENERGY STAR program suggests it may be time to consider replacement if your air conditioner or heat pump is older than 10 years, or if your furnace is older than 15 years. However, age is only one factor. Ask the technician to show you what failed. They should explain the condition of your outdoor coil, indoor blower, and heat exchanger. When repairs are possible, your contractor should give you a written price for the repair alongside the replacement options, allowing you to compare the costs.

How Will You Size the New System?

Sizing a new system based only on the square footage of your home is a common mistake. Your contractor must look at the whole home to determine the correct equipment size. This means looking at:

• The number of rooms and overall layout.
• The quality and depth of your attic insulation.
• The size, type, and age of your windows.
• The sun exposure your house receives during the summer.

They also need to consider how your family uses the house. An oversized system turns off and on too often. An undersized system runs constantly during the Las Vegas summer, struggling to reach the temperature on your thermostat.

Are My Existing Ducts Suitable?

The ductwork in your attic or crawlspace plays a critical role in your system performance. The ENERGY STAR program notes that in a typical house, about 20 to 30 percent of the air moving through the ducts is lost to leaks, holes, and poorly connected ducts. Monsoon dust and attic heat are hard on ductwork over the years. Ask your contractor to inspect your existing ductwork. They may recommend duct repair, sealing or airflow balancing so more of the air reaches every room.

What Equipment Brands and Efficiencies Do You Offer?

Efficiency rules change, and your new equipment must meet current federal standards. The US Department of Energy places Nevada in the Southwest region. Since January 1, 2023, new split central air conditioners must meet a minimum of 14.3 SEER2. Heat pumps nationwide must meet 14.3 SEER2 and 7.5 HSPF2. You should also ask about refrigerants. Since January 1, 2025, new residential air conditioners and heat pumps are made for lower impact refrigerants, such as R-454B and R-32, instead of older formulas. Ask your contractor to explain these efficiency ratings and how they apply to the models they recommend.

What Pricing and Guarantees Do You Offer?

Financial surprises have no place in home service. Ask your contractor if they use flat-rate pricing. With this pricing model, the price is agreed before work starts and does not change once approved. You should receive a free, in-home, written estimate on new systems and replacements. Understanding your coverage protects your investment. Keep the different kinds of warranties separate. First, ask about the manufacturer parts warranty. The length of this warranty is set by the manufacturer, and registration may be required. Second, ask about the workmanship warranty. Kestrel Heating & Air installations carry a two-year labor warranty. Finally, confirm that the contractor offers a satisfaction guarantee on every job.
