Buying a new HVAC system for your home is an important decision that requires careful consideration.

You want to make sure you get the right system that meets your needs and fits into your budget.

To help ensure you make the best choice, there are several questions you should ask before making this purchase.

These include questions about size and efficiency, installation requirements and warranties, as well as any additional features or technologies available with different systems.

Taking the time to research these topics will ensure you get the best value for your money when investing in a new HVAC system for your home.

By understanding the answers to these questions, you can make an informed decision that will provide years of reliable comfort and energy savings.

If you're in the market for a new HVAC system, here are ten questions you should ask each installer before deciding...

1)) What Kind Of HVAC System Do I Need?

The type of HVAC system that you need depends on the size and layout of your home, as well as your climate and budget.

Some factors to consider are the number of rooms in your home, ceiling heights, location and more.

Ultimately, a professional HVAC technician can assess all these factors to determine which system will be best for you.

There are three main types of systems: central air conditioning units; heat pumps; and ductless mini-splits.

Each has their own advantages when it comes to heating and cooling efficiently.

To make sure that you find the right system for your needs it is important to speak with an experienced HVAC professional before making any decisions.

2)) How Efficient Should My HVAC System Be?

Your HVAC system should be as efficient as possible while still meeting the needs of your home or business.

The most efficient systems use the latest technology and have earned the ENERGY STAR® label.

An ENERGY STAR® qualified HVAC system can save you up to 20% on cooling costs compared to a standard system, making it a smarter investment in your long-term comfort.

In addition, look for an HVAC system with an AHRI Certificate of Performance (COP)—this indicates that its laboratory tested efficiency level was met or exceeded in actual field tests conducted by AHRI certified professionals.

This certification is especially important if you plan to purchase and install solar panels, since your HVAC efficiency will directly impact how much energy those panels generate annually.

By choosing an energy-efficient model you’ll reduce environmental impact, lower utility costs and maximize comfort for years to come!

3)) What Size HVAC System Should I Buy For My Home?

The size of the HVAC system you should buy for your home depends on a variety of factors including the square footage of the house, number of occupants, local climate, insulation levels and lifestyle habits.

To ensure accurate sizing and comfort level in your home, it is best to consult a professional HVAC contractor who can measure these metrics and recommend the right-sized system for your needs.

4)) What Is The Difference Between A Single-Stage And A Two-Stage Air Conditioner?

A single-stage air conditioner has one speed, meaning it runs at either full power or off.

A two-stage air conditioner is more efficient and has two speeds: a low setting for mild days and a high setting for the hotter days of summer.

The two-stage option gives you greater control over your comfort levels, while also using less energy than the single-stage system, resulting in lower utility bills.

5)) How Much Does It Cost To Install A New HVAC System In My Home?

The cost to install a new HVAC system in your home will depend on the size and type of system you need, as well as any additional elements that may be required for installation.

Typical homeowners can expect to spend between $4,000 and $15,000+ for a full HVAC system installation.

This price range includes both labor and materials. However, many factors can influence the total cost including location, size of the property, energy efficiency requirements and more.

It is best to contact an experienced HVAC contractor to get an accurate quote for your particular project.

6)) Will My Current Power Supply Be Able To Handle The New HVAC System?

It depends on the configuration of your current power supply and the size of the new HVAC system.

The best way to determine if it will be able to handle it is to consult a professional electrician who can evaluate your existing set up and advise you as to what needs upgrading or replacing in order for it to properly work with the new HVAC system.

7)) Are There Any Special Features Or Technologies That I Should Look For In An HVAC System?

When looking for an HVAC system, you should look for features like a two-stage compressor, high efficiency air filters, programmable thermostats, zoning systems and air movement systems.

High efficiency air filters capture more dust and allergens from the air which can help create a healthier home environment.

Programmable thermostats allow you to set the temperature levels in your home automatically so that your house is always at the optimal temperature based on when you’re away or asleep.

Zoning systems enable you to control which areas of your home are heated or cooled - this can help save energy by ensuring that only rooms that need cooling get it.

Air movement systems provide better circulation throughout the home for even temperatures with little energy use.

These features will increase the cost of an HVAC system, but they can also offer numerous benefits in terms of comfort and energy savings over time.

8)) What Is The Best Warranty Option Available For An HVAC System?

The best warranty option available for an HVAC system will depend on the type of system and make.

Most HVAC systems come with one of two types of warranties: limited or extended.

A limited warranty typically covers parts and labor for a set period of time, usually 1-2 years from the date of purchase.

An extended warranty extends coverage beyond what's offered in a limited warranty and may even include service calls, repairs, or replacement costs if something goes wrong after the initial period has ended.

It is important to read the fine print carefully when reviewing any warranties before making your purchase decision.

9)) How Often Should I Maintain And Service My HVAC System?

To ensure optimal performance and extend the life of your HVAC system, regular maintenance and servicing should be performed at least once a year.

During a routine service visit, an HVAC technician will inspect all components, check for leaks or other signs of wear and tear, clean the condenser coils and evaporator fins, check refrigerant levels, adjust controls settings as necessary to increase efficiency, and more.

A well-maintained HVAC system can save you money in energy costs over the long run!

10)) Can I Upgrade Or Add Components To My Existing HVAC System Over Time?

Yes, you can upgrade or add components to your existing HVAC system over time.

Depending on the age and size of your system, it may be possible to replace or improve specific parts such as the motor, fan belt, filters, thermostat, and heating coils.

You may also want to consider adding a zone control system which allows you to adjust temperatures in different areas of the house separately.

Talk with an HVAC professional before making any changes or additions so that they can inspect your current system and determine if the upgrades are safe and necessary for optimal performance.


When it comes to buying a new HVAC system for your home, it’s important to do your research and ask the right questions.

You should consider factors such as energy efficiency ratings, installation costs, maintenance requirements, warranties, and more before making any purchase decision.

Make sure that you get quotes from multiple companies so you can compare prices and features of each unit.

By taking these steps beforehand and asking the right questions about cost-effectiveness and long-term savings potential, you will be able to find the best HVAC system for your needs at an affordable price.
