How to Get HVAC Estimates: What Fair Pricing Looks Like and How to Avoid Overpaying

Fixing or replacing a heating, ventilation and air conditioning system (HVAC) quickly is essential if you suspect an issue — especially if it’s particularly hot or cold outside. But doing so doesn’t come cheap.

An HVAC replacement can cost you thousands or even tens of thousands of dollars. According to CBS News, a full HVAC replacement runs anywhere from $5,000 to $28,000 nationwide, including equipment and labor, depending on your system and home size.

That can make the process intimidating, but it doesn’t mean you should jump at the cheapest option. A high-quality estimate should help a homeowner understand exactly what products are being proposed, why they’re needed and what value the homeowner is getting for their money. Here’s what to expect from an HVAC assessment and estimate, and how to know if you’re overpaying for your system.

What a HVAC in-home assessment should include

HVAC estimates can vary widely based on factors such as the layout of your home, the complexity of an installation, local labor costs and more. But the first step is typically an in-home assessment so your contractor can determine what your house specifically needs.

Here are some key steps of that assessment:

• Load calculation: A contractor can’t simply measure where your HVAC system will go and choose a system size based on the measurements. Instead, they do what’s called a “load calculation,” which pinpoints the heating and cooling requirements of your home. Oversized systems can waste energy, but undersized ones can have a hard time keeping up.
• Ductwork inspection: They will also look for insulation issues, leaks, restrictions in the airflow and more. This can help determine whether the ducts need to be replaced.
• Equipment check: This step entails assessment of the furnace, air conditioner and heat pump. The contractor will check for wear and tear, refrigerant levels and whether the drainage process is working well.
• Airflow and comfort: The technician will ask you about your comfort in the home, if there are specific problem areas and whether you need air purifiers and humidifiers.
• Restraints: The contractor will have to check on whether there will be issues placing the condenser or heat pump where they need to go, if there is clearance around the unit and other restraints.

Expected estimate line items

A good HVAC estimate will break down the costs so that you can understand exactly what you’re paying for. The most extensive part will likely be the estimated material and equipment costs, including brands, models and efficiency ratings for the:

• Furnace
• Air conditioner
• Heat pump
• Air handler
• Thermostat
• Extra accessories, such as humidifiers or smart thermostats

There will also be a section for labor and installation costs, including the cost of:

• Removing the old hardware
• Installing the new hardware
• Testing the new system
• Ductwork, if needed

The estimate will also cover logistics and permits, including:

• Permit and inspection fees
• Removal and disposal fees for removing the old equipment and disposing of old refrigerant
• Equipment rental, if necessary

Finally, look for warranties and agreements, including the:

• Manufacturer warranty
• Labor warranty

Red flags to watch for

If an estimate seems too good to be true, it probably is. Be sure that the estimate isn’t vague or significantly lower than what the company’s peers are offering. If an estimate simply says that the contractor will install a new HVAC system or replace the furnace and AC without details such as the model and efficiency ratings, you may want to look elsewhere.

High-pressure sales tactics can also be a red flag. You shouldn’t feel rushed into making a decision

Scott Urquhart, sales and operations executive at ARS, says the most important advice he can give people shopping for HVAC systems is to make sure that the company offers a money-back guarantee.

“You get to run this system for a year, and if there’s anything you don’t like with it, the company has to make it right,” Urquhart says. “You need recourse as a consumer in the event that you’re not satisfied, because there are a lot of risks you’re taking as a consumer when you have somebody attach something to your house and put something in your house that you just do not know. So you need to be covered in the event that there is some sort of problem.”

How to compare estimates

Don’t go with the first estimate you receive. Instead, collect at least three and create a side-by-side checklist.

Compare the equipment (including brands and models), system size, efficiency ratings, labor costs, ductwork, permits included, warranty length and project timeline. This will give you a sense of whether the lowest estimate would entail the same amount of required work as the costlier ones.

If in doubt, talk to the contractor. You can ask how your system size will be determined, what happens if issues pop up after the installation, whether ductwork is included and more. A good contractor will be able to answer all your questions in detail.
