Upgrade and Save on Your Air Conditioner

How long have you owned your air conditioning unit? If you bought it more than 10 years ago, consider an upgrade. HVAC technology has become much more efficient since you bought your last air conditioner. Upgrading to a new model could cut your energy costs by up to 40 percent, according to the U.S. Department of Energy (DOE).

How Do Air Conditioners Work?

Your air conditioner does not add cold air to your home—it removes heat. In simple terms, the equipment harvests warmth and humidity from the air and sends it outside. From there, fans blow the leftover chilled air through your ductwork and into your living space.

Your air conditioning unit has four main components:

  • Evaporator coil
  • Compressor
  • Expansion valve
  • Condenser

Your air conditioner uses a chemical called refrigerant to absorb heat. You may be familiar with Freon®, the most common name brand of refrigerants.

Here’s how the cooling cycle works: 

  1. The evaporator coil extracts heat from inside your home. The refrigerant soaks up the heat.
  2. The compressor puts pressure on the refrigerant.
  3. The condenser releases the heat outdoors.
  4. The expansion valve regulates the refrigerant’s flow back to the evaporator.

Air Conditioner Installation and Replacement

Should you get a new air conditioner or keep the old one? As a homeowner, you’ll have to answer that question at some point—and it’s not always an easy decision. On average, cooling units last 10 to 15 years with good maintenance.

Besides age, here are some signs it’s time to get a new AC:

  • High energy or repair costs
  • High humidity levels
  • Insufficient cooling

Like an old car that you have to keep taking to the shop, an air conditioner that frequently breaks down is likely ready for retirement. Repair costs add up quickly. At some point, it may be more cost-effective to upgrade.

Our team at Mission Comfort will work closely with you to find a cooling solution that fits your home and budget. With the finest equipment and a team of qualified HVAC experts, we’re ready to deliver a product that exceeds your expectations.

What Is a Good SEER Rating?

The term SEER stands for seasonal energy efficiency ratio. It measures how much energy your air conditioning system uses to operate. The higher the SEER number, the more efficiently your air conditioner will run.

How Much Money Can a New Air Conditioner Save You?

Our SEER2 (Seasonal Energy Efficiency Ratio 2) energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit’s SEER value and compare it to a newer, more efficient SEER2 unit. You can even customize it to better match your home’s system for a more accurate calculation.

I have so many wonderful things to say, but I’ll try to keep it simple… simply put – De’Asia the bomb.com and she smells good too!! The knowledge, professionalism and experience are unmatched! I met Kenzer. I think he was in training. Very good energy and will definitely be a wonderful asset to this company. I met Jensen too – who is the expert to those two amazing experts! From the top to the bottom, from the owner to the techs, each of them communicating with me through each visit. Cami has outstanding customer service!!! I actually prayed about a service I was thinking of getting (the kick start) and decided to get it. So I text her at 8  o’clock PM on a Friday night thinking she would reply back on Monday and she responded immediately. I was blown away! In closing, feel like I am more than just a customer, but I feel like they are my trusted friends.

“Before contacting Mission Comfort, I did a lot of reviewing of the other HVAC companies available in my area. Something about the other companies didn't sit well with me. I stumbled upon Mission Comfort and I knew I had found my people. Jhensen was my tech and was sweet as pie and really informative. He let me know exactly what the issue was, what I needed to look out for in the future and any other recommendations he had for me. He worked quickly and with respect for my home. I've found my HVAC people and will be using them exclusively going forward.”
