For a consumer, nothing is worse than spending money to buy things you don’t understand. Your hard-earned cash should always go towards informed purchases, and at Done Plumbing & Heating, we understand that HVAC systems are not exactly the simplest of machines to understand. If you’re finding it difficult to select an air conditioning system for your home, don’t fret; here is a rundown of all that you should know.

How It Works

Like a refrigerator, but for more than just leftovers. Like the trusty kitchen appliance, air conditioners rely on the shifting temperature and pressure of Freon, the refrigerant that flows through the machine’s coils. It all starts at the compressor, which does as its name suggests and raises the pressure of Freon. This propels the hot gas through a series of coils, which are in contact with air, cooling the Freon down and liquefying it.

With its remaining pressure, the cold liquid Freon enables the mechanisms responsible for cooling your home. In the process of lowering the indoor temperature, the Freon will absorb as much heat as it can from the air, turning it into hot, low-pressure gas before returning to the compressor and starting the process anew.

What You Need

You only need to consider three things when shopping for an AC unit: capacity, efficiency, and reliability. A simple way of measuring these three is by checking your machine’s Seasonal Energy Efficiency Ratio (SEER). As of 1 January 2023, a new energy efficiency standard is in effect known as SEER2. HVAC systems manufactured after this date give a more reliable efficiency rating and the minimum standard has been raised. The new minimum SEER2 ratio is 13.4, but we would not recommend going past 15.3 if you wish to get the most out of your money, since costs are quick to go up even with the diminishing returns on savings.

Something to keep in mind is that this more rigorous efficiency standard comes at a cost. 2023 HVAC systems could be $2,000 or up to 20% more expensive. The good news is that we are able to continue selling 2022 inventory while stock lasts. Reach out today to grab a less expensive unit.

You may also refer to our technicians in determining the perfect unit for your home, since Done Plumbing & Heating is a factory-authorized dealer for Carrier. Our partnership with one of the most trusted HVAC system manufacturers in the world is just another way for us to provide services in addition to air conditioner repair in Denver.

Don’t hesitate to ask any of our staff for assistance when it comes to HVAC unit selection. Each machine is a major investment, and we strive to ensure that every purchase is for customers who are fully knowledgeable and confident in their decision.

Let’s be honest: Nobody thinks about their plumbing and heating until there’s a problem.


What most people don’t realize is that most of those problems can be anticipated and often avoided with regular maintenance – usually at a far lower cost than a repair or replacement.

Reviews


“This past week I had the need for a plumber and I reviewed the telephone book and selected from the advertisements your company to attend to the matter. The company sent Austin Steinbach to attend to and review the problem. He is a very knowledgeable young man who communicates well and does his work in a very thorough and professional manner. I was very satisfied with his service. Mr. Steinbech is a credit to your company. Very often in communities someone asks whether they are aware of a plumber or other technician that can be recommended. In this regard, I am comfortable in recommending Mr. Steinbech and your company. Thank you for the service rendered.”

“Quick & competent work done to high satisfaction. Darrell Begay provided quick service and very professional work when he came to install a new toilet seat. We had not been able to do the work ourselves, so it was a relief to have Darrell and Done Plumbing get here so quickly to take care of the task. We appreciate all Done as done for us”

“Just a note to tell you of our recent positive experience with Kieth Croft. We found him to be friendly, knowledgeable, & efficient. When an issue arose with the clean-outs, Kieth quickly resolved it to our satisfaction & to the way he had previously described. From the estimate to the conclusion of the project we had confidence in Kieth. He is a good ambassador for your company.”

“Just a note of thanks for being the Best plumbing and heating company. I have used you often and have been impressed every time. I called for a drain cleaning and was told a technician could come the same day. He arrived an hour ealier than was quoted, was very professional and did a great job at a very reasonable price with my coupon that he honored. I would never use another company and would recommend you to anybody that needs help. The technician that did such a great job was Austin, but every technician you have sent has been the best. Thanks again for such a wonderful company”

~ Karla W Golden, CO

“It was very professional, prompt & the technician explained many things well. Very happy throughout the whole process – from the customer service rep who answered the phone this morning to the technician explaining building codes to me.
