Air Conditioning / Heating

San Diego Air Conditioning System Replacement

If you are considering a new air conditioning system, then you have come to the right place.  THA is focused on four primary objectives:
  • We strive to ensure you get the most comfortable air conditioning system for your investment.
  • We make it a priority that the systems we put in place are the safest and healthiest for your family.
  • We go out of our way to make sure you get the most energy-efficient cooling system around.
  • If you are experiencing problems with your current system, we will inspect and recommend the best course of action.

Let's Talk
When a THA Comfort Advisor arrives at your home, we make sure we understand the issues you are dealing with first, before we provide a solution. If is a problem you are having with your current air conditioning system, we will inspect it to see what can be done and if it can be repaired. We want to make sure we do what is best for you and your family.

No only that, we will go room-by-room and see how your cooling system works in that room.  If it is having problems, we will determine why.  We also go in depth to see if you are suffering from any allergies, excessive dust, etc. because this could be due to your air conditioner as well.

We will then discuss your energy bills and compare it to homes that are considered to be energy-efficient and see how your home stacks up.  If you are wasting energy and money, we will figure it out and fix it.

Measuring Your Home

Another great thing we can do for you is not quote you a new system based on the size of your current system. We take a more thorough approach.  This includes doing a Manual J Load calculation of your home.

You will be pleased to know we take everything into account, including important factors such as room size, window sizes, insulation levels, even the type of siding, plus other important aspects of your home that will impact your energy bill.

Doing all these things together will ensure the best solution for your home.

Measuring Current System Performance
Next on our list of steps is to measure how your current HVAC system is performing.  We want to know where the problems may be.  We will inspect your current duct work to make sure it can handle a new high-efficiency system.  It would be a waste of money if your duct system could not make it work efficiently.

We will also take into account the insulation in your attic. This plays a huge role in keeping your home cool in the summer heat.  Inefficient insulation can leak heat into your home.

Rating Your System

Once we have performed those steps, we will have a complete picture and understanding of how your current home is performing in regards to heat load and measurement data on your exisiing heating and cooling system.

At that point we can easily calculate how well or how poorly your system is working compared to comparable San Diego area homes.


Our Recommendations

Finally at this point, we will feel comfortable in making the best recommendation for your home.  We don't come in hoping to charge you some pre-determined price.  All homes are different and doing all those checks and evaluations will help us determine what are the best options for you.  This will help us help you meet your desired comfort and energy savings goals. You will have the best options for your specific needs and budgets.

Our goal is to give you all the information you need to make the best decision possible for you and your family. This process has been well received by many past customers and has taught them more about their system than any other contractors around.


Once you have decided on one of our systems that will best meet your needs, at that point we can schedule a time for installation of the air conditioning system.  It typically takes only a day to install, but it can take longer if there is more work to be done such as duct replacement and any upgrades you may request to be installed.

Our installation process is simple and we make sure to protect your home during the installation.  We protect your carpets by wearing shoe covers and using drop cloths. Any other debris is removed promptly by our technicians.

Upon completion of the installation, we then run several tests to make sure your new heating and cooling system is working throughout the home. We make sure it will perform properly and gives comfort in each room.
