Picking a new heating and cooling system is difficult. It’s important to think about different factors when it comes down to choosing the right HVAC unit for your home.

Keep reading to figure out which of these seven factors are most important to finding the best heating and cooling system replacement for you. 

1. Length of Time 

The length of time you will be living in your home is important because it will help determine how much you are willing to spend on your heating and cooling system replacement. If you plan on selling your home soon then you may not want to spend too much money on a new system. Although, the better the system the more value it will add to your home. 


If you plan on living in your home for more than ten or fifteen years then you should choose a model that will keep you comfortable and save you money long-term. A higher efficiency system will lower your energy bill and keep you comfortable. Even if you have to pay more for a higher efficiency system, the low cost of the energy bills should make up for it.

2. Necessary Heating and Cooling Coverage

Are you in need of a heating and cooling unit to cover the whole house? A system that is needed to heat and cool a larger amount of space is going to cost more to install. However, if you only need to cover a smaller area then there are some better cost-effective options for you. 


A ductless heater and air conditioner will provide as much comfort as a central unit with the added benefits of cheaper installation. It is cheaper to install because it has less parts to work with. Call a Cedar Hill air heating and air conditioning company to work out a plan for how much space you need covered. Then, call your technician to learn more about ductless AC services

3. Efficiency HVAC Ratings

Air conditioners have ratings that determine how efficient the system is. This is an important factor to consider when thinking about what type of HVAC replacement unit you will buy. There are two types of efficiency rating that are important to note:


  • Seasonal Energy Efficiency Ratio (SEER) is used to rate the efficiency of air conditioners and central units. 
  • Annual Fuel Utilization Efficiency (AFUE) rating is used for gas furnaces. 


The higher the rating the more efficient the air conditioner will be. The efficiency of a unit will also save you money on the electric bill at the end of the month. 

4. Type of Blower Fan

The blower fan that gets installed into your replacement unit will be a factor in how efficient your HVAC unit is. Typically, the older the fan the more electricity it will need to function. Most older fans are single-speed. This means it does not have the capability to withstand huge temperature changes and will often turn on and off.  


Consider incorporating a variable speed blower fan into your air conditioning replacement. A variable speed blower has an electronically controlled motor that can handle temperature shifts with ease. Upgrading to this model will make for a silent, efficient and low fuel unit. 

5. Ventilation Systems

Another factor in choosing a replacement for your heating and cooling unit is the type of ventilation system that you want. Ventilation is important to consider because it provides comfort and better air quality. For homeowners that are nervous about outdoor air leaking through into their home, better ventilation should be a priority. 


Better ventilation will help with efficiency in your air conditioning unit because it will work harder to filter your air. Also, mechanical ventilation may be installed to help prevent excess moisture and debris that could be coming in from your unit. Contact your local Cedar Hill air heating and air conditioning company to find out how new ventilation will help with indoor air quality.

6. Service Agreements 

Annual maintenance service agreements can be discussed with the HVAC installation company beforehand to ensure that you have a maintenance schedule in place. Although you do not need a service agreement to have an HVAC unit installed, it is highly beneficial and can save you a lot of money. 


A service agreement makes annual maintenance and potential repairs cost less through discounts. This is an affordable way to ensure your HVAC unit will be maintained and repaired by a professional.

7. Size of the Unit

In order for your HVAC unit to last a long time and remain efficient, it is important that you get it correctly sized. The size of the unit is dependent on what your home needs for heat and cooling.


 If you have a larger home, then you may need a larger unit to generate more heat or cooling to make it comfortable. If you have a smaller home, you won’t need as large of a unit. This is important because a unit that is too big will increase your energy bills and a unit that is too small won’t effectively heat and cool your home.
