How Do I Know What Air Conditioner I Need?

Deciding on which type of air conditioner you need for your space can be quite daunting, but the pros at John Stevenson Plumbing, Heating & Air are here to help. One of the primary items you’ll want to consider is what size system you’ll need - a new AC that is the correct size for your home and climate is essential for efficiency. An undersized air conditioner will often become overworked as it will struggle to provide enough cooling power to keep your property comfortable, which can lead to a wearing down of the unit and expensive repair costs. On the other hand, an oversized air conditioner will often short cycle as it's too powerful for the space, leading to a drop in energy efficiency, higher energy bills, and early breakdowns. That’s why we recommend speaking with our Carlsbad AC installation professionals who can help you assess what size system you’ll need and what factors may influence this.  

In Order to Install the Correctly Sized Air Conditioner for Your Space, You’ll Need to Consider:

  • The size and square footage of your home
  • The state of your insulation 
  • The climate in your region
  • The quality of your ductwork
  • The number of occupants in the home 
  • The number of windows your property has
  • The level of sun exposure your home receives 

With these measures taken into consideration, you’ll be able to have the right AC installed into your home, offering greater peace of mind. Investing wisely in an effective air conditioner can keep energy costs significantly lower while providing comfort throughout the warm months.

How Much Does It Cost to Install an AC Unit?

When it comes to air conditioners, the cost of installation can vary greatly. The size of the AC unit, the complexity of initial setup, labor, and additional components needed are all factors that can influence how much installation will cost. Furthermore, if ductwork needs to be installed or replaced to accommodate the new air conditioner, then the cost of the installation could be affected. Additionally, whether your current air conditioning unit needs to be removed from your property or not, can also have an influence on overall new AC installation cost. Ultimately, the cost of air conditioning installation depends on your home and specific needs. 

While the cost of a new AC system may be daunting, investing in installation when your system is outdated or showing signs of a breakdown can actually save you more money in the long run.

Benefits of Installing a New Air Conditioner:

  • Improved energy efficiency
  • Lowered energy costs
  • Enhanced indoor air quality 
  • Improved airflow and cooling capabilities
  • Quieter performance when running
  • Increased home value

Frequently Asked Questions
  • Should I replace or repair my AC unit?

    Many customers ask if they should repair a broken air conditioning unit versus a full replacement. Often, a well-maintained and newer AC unit will be able to be repaired depending on the issue. If it is a part under warranty, replacement of the part is a simple fix. However, if the AC is more than 10 years old, has not been regularly serviced, or is in need of a major repair, replacement is the best option. Our team will provide all available options for homeowners to consider.

  • What's a Pre-Installation Evaluation? Does My New A/C Need One?

    In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at John Stevenson Plumbing, Heating & Air how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.

  • Is Your Home's Ductwork & Design Able to Handle a New A/C System?

    Often your old, existing ducts can’t handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.

  • What Type of Central A/C Unit Should I Install?

    Here’s where the load calculation comes into play, as you want to pick the right size A/C unit to install – either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at John Stevenson Plumbing, Heating & Air, they’ll know which A/C unit is perfect to install in your home at the lowest price.

  • How Much Does it Cost To Get My Air Conditioning Unit Installed?

    The price of replacing your air conditioning unit depends a lot on the size of the unit you need to fit the size of your house. But no matter what unit you pick out for your home, ask an expert at John Stevenson Plumbing, Heating & Air for fast answers & reliable service. Trained technicians can come to your house to give you an upfront, transparent installation report, as well as consult you on what unit your home will need.

  • Why Would My Air Conditioner Stop Working?

    Breakdown of your home A/C unit can stem from many different things, from an electrical issue to the compressor being misaligned or broken. Luckily for you, the team at John Stevenson Plumbing, Heating & Air is trained in diagnosing the problem and presenting you with a competitive price to fix or replace and install your new A/C unit.
