6 Ways to Extend the Lifespan of Your Air Conditioner

A well-maintained air conditioner is built to last about 15 years, but if poorly maintained, this lifespan will likely be much shorter. To ensure its longevity and efficient performance, it’s important to be proactive and regularly maintain your AC unit. In this article, we explore several effective ways to extend the lifespan of your air conditioner, helping you get the most out of your investment while avoiding unnecessary repairs.

1. Regular Filter Changes

One of the simplest yet most important steps in maintaining your air conditioner is regularly cleaning or replacing the air filter. Dirty filters can restrict airflow, forcing the system to work harder and increasing wear and tear. All AC units are different, so be sure to follow the manufacturer guidelines for changing or cleaning your filter.

2. Consistent Cleaning

Dirt, debris, and dust will accumulate on the external and internal components of your air conditioner. The condenser coils, evaporator coils, and the surrounding areas should be cleaned once per year to ensure proper airflow and heat transfer. You can do this yourself with a soft brush or vacuum cleaner, or you can hire a professional technician. Be sure to keep the area around the outdoor unit clean and free of plants, furniture, and debris as well.

3. Proper Thermostat Usage

Your thermostat can help reduce the strain on your air conditioner. Set your thermostat to a moderate temperature and avoid drastic temperature adjustments, as frequent cycling can put unnecessary stress on the system. Consider a programmable or smart thermostat to automate temperature settings and optimize energy efficiency.

4. Regular Professional Maintenance

It’s important to get your AC unit regularly inspected and tuned-up. Professional maintenance can identify and address minor repairs before they escalate, optimize system performance, and ensure all components are in proper working condition.

AC Refrigerant: Everything You Need to Know

AC refrigerant is a vital component of your air conditioning system, responsible for transferring heat and cooling the air. Below, we provide you with everything you need to know about AC refrigerant. If you ever have any questions or concerns about AC refrigerant, always consult a professional HVAC technician.

What is AC Refrigerant?

AC refrigerant is a chemical that absorbs heat from indoor air, carries it to the outdoor condenser unit, and releases it into the surrounding environment. It continuously changes from a low-pressure gas to a high-pressure liquid and back to a gas, facilitating heat transfer and cooling.

2 Types of AC Refrigerants

  • R-22 (Freon): R-22 was commonly used in older AC systems but is being phased out due to its harmful environmental impact. Its production and import have been banned in several countries. It is being replaced by more environmentally friendly alternatives.
  • R-410A: R-410A—also known as Puron—is the most widely used refrigerant today. It is chlorine-free, ozone-friendly, and is very efficient. AC systems designed for R-410A are more energy-efficient and comply with environmental regulations.

Refrigerant Efficiency and SEER Ratings

The efficiency of AC refrigerants is measured by the Seasonal Energy Efficiency Ratio (SEER) rating. Higher SEER ratings indicate greater energy efficiency and cost savings. AC systems using newer refrigerants like R-410A tend to have higher SEER ratings. Click here to learn more about SEER ratings.

Refrigerant Leaks

Refrigerant leaks can be caused by aging components, corrosion, or physical damage to refrigerant lines. Signs of a refrigerant leak include reduced cooling, longer cooling cycles, frozen lines, or hissing sounds near the AC unit. If you suspect a refrigerant leak, call for an emergency AC repair as soon as possible.

Proper Refrigerant Charge

Correct refrigerant charge is crucial for your air conditioner’s performance. Too much or too little refrigerant can lead to decreased cooling efficiency, increased energy consumption, and potential damage to the compressor.

If your AC system requires a refrigerant recharge, it is crucial to hire a professional HVAC technician. They will repair any leaks before adding refrigerant to the system. Attempting to recharge refrigerant yourself without addressing leaks can lead to wasted refrigerant and environmental harm.

Note: if a technician says you need a recharge and does not check for leaks, this is likely a scam. Refrigerant runs through a closed system and does not run out. Click here to learn more about common HVAC scams.


While it is helpful to know about AC refrigerant, certain things should be left to a professional, including choosing the right refrigerant type, ensuring proper refrigerant charge, and addressing leaks.

What Is a SEER Rating and Why Is It Important?

When shopping for a new air conditioning system, you may come across the term “SEER rating.” SEER stands for Seasonal Energy Efficiency Ratio and is an important metric for measuring the efficiency of air conditioners.

Understanding SEER ratings can help you choose an AC unit that maximizes energy efficiency while keeping your home comfortable. Below, we’ll discuss the importance of a SEER rating and all the need-to-know SEER rating details.

NOTE: a reputable HVAC company can recommend the best AC unit for your home and climate. While we like to provide helpful information, we strongly encourage seeking the advice of a professional and not choosing an AC unit yourself.

What is a SEER Rating?

The SEER rating is a measurement of an air conditioner’s cooling efficiency over an entire cooling season. It represents the ratio of cooling output (measured in British Thermal Units or BTUs) to the electrical energy input (measured in watt-hours). A higher SEER rating indicates greater energy efficiency, meaning the air conditioner can cool your home using less energy.

The Importance of SEER Ratings

Choosing an air conditioner with a higher SEER rating can provide you with energy efficiency, lower short-term bills, and even lower long-term bills. AC units with higher SEER ratings consume less electricity, reducing your energy bills and saving you money. And, even though air conditioners with higher SEER ratings may have a higher upfront cost, the long-term energy savings can outweigh the initial investment.

SEER Rating Guidelines

The minimum SEER rating requirements vary by country and region. In the United States, for example, the minimum SEER rating for new air conditioners ranges from 13 to 14; 13 for northern states, 14 for southern states. Here in Colorado, the minimum SEER rating is 13, though many new central AC systems are 16 or higher.

Factors to Consider

When selecting an air conditioner based on SEER rating, consider the following factors:

  • Climate: If you live in a region with a milder summer like Denver, a lower SEER rating may be sufficient. In hotter climates, investing in a higher SEER-rated unit may be a better option for long-term savings.
  • Usage Patterns: If you use your air conditioner frequently, a higher SEER-rated unit can yield greater long-term savings. However, if your AC usage is limited, a lower SEER-rated unit may still be cost-effective.
  • Budget: While higher SEER-rated units provide better energy efficiency, they often come with a higher price tag. Consider your budget and weigh the initial investment against long-term energy savings.

How Often Should I Get an Air Conditioner Tune-Up?

Your air conditioner is a valuable investment in your home’s comfort and well-being and requires regular maintenance to ensure that it runs effectively and efficiently. Regular air conditioner tune-up services can help extend the lifespan of your AC system, improve its energy efficiency, and reduce the likelihood of costly breakdowns or repairs. But how often should you get your air conditioner serviced?

The rule of thumb is to get an air conditioner tune-up once per year, preferably during the spring season, but there are several factors that determine how often you should get an AC tune-up. Below we discuss some of these factors and when you should consider getting tune-ups more often. When in doubt, ask your HVAC technician what they recommend!

1. Age of the AC Unit

If your AC unit is less than five years old and has been well-maintained, it is recommended you get the unit serviced once a year. However, if your air conditioner is older than five years, it should be serviced twice a year. This ensures that it is functioning at its best and will prevent repairs.

2. Frequency of Use

If you live in an area with hot and humid summers and rely heavily on your air conditioner, it’s recommended to have it serviced twice a year. Here in Denver, our summers are quite mild, but some years are much hotter than others.

5 HVAC Myths Busted

When it comes to home appliances, there are plenty of age-old myths that promise less maintenance, better performance, and money saving. The same can be said for air conditioners and furnaces. While many of these myths come with good intent, some are downright terrible practices to follow.

Below are 5 common HVAC myths and why each myth could actually be costing you money and hurting your AC unit or furnace.

Myth #1: Cranking the thermostat will heat or cool your home faster.

If you crank your thermostat up to a very high temperature or down to a very low temperature in hopes it will heat or cool faster, this will not actually accomplish anything. Your AC unit or furnace will reach your desired temperature as fast as it can without overworking. If the unit shuts off before it reaches your temperature, it likely means it is shutting off to prevent the unit from overheating and will resume when ready.

Myth #2: The best unit is the biggest and most expensive.

Bigger is not always better when it comes to air conditioners and furnaces. An oversized unit will often short-cycle, which will decrease the lifespan of the unit and require more repairs than usual to keep it going. Your monthly utility bills will also be much larger than necessary. From purchasing the unit to maintaining it, you will be overpaying.

It is important to note that an HVAC professional selling you a larger unit than necessary is a common HVAC repair scam. There are dishonest contractors who will recommend you choose the biggest unit with no regard for the type of unit or size of your house/building. Units that are oversized are more expensive to install so the contractor can charge more for the job. They are also more expensive to run in the long term and will cost more in service and maintenance. Click here to see our full list of common HVAC repairs to keep an eye out for.

Myth #3: If my unit is working, I don’t need a cleaning or tune-up.

Just because your unit is running does not mean it is running at peak efficiency, does not need to be cleaned, or every part is in perfect condition. Furnace and AC maintenance should be proactive, meaning it should happen before a breakdown takes place. Furnace tune-ups will keep your unit running longer and more efficiently, saving you money on your monthly bill and keeping you from replacing the unit prematurely.

Myth #4: Closing vents will save you money.

When you close vents in a room because it is rarely used or too hot/cold, the closed vent creates pressure in the air vents and an imbalance in the unit. In general, your system pulls in as much air as it needs to heat or cool your home. When you close some vents, your unit is pulling in more air than it is pushing through the ducts, thus creating pressure on the unit. This pressure can cause leaks in your ductwork and unnecessary wear and tear on your system’s blower. It’s best to keep your vents open and keep the air circulating throughout your home.

Myth #5: The filter only needs to be replaced once every year.

Changing your filter once per year might be correct for some units and filters, but this is definitely not a one-size-fits-all approach. Some manufacturers will recommend changing your filter several times a year at a minimum. In addition, if you have several pets in your home, you should change your filter more often than a pet-free home. Always check with the manufacturer recommendations, and make sure to check your filter from time to time.


There are plenty of HVAC myths out there, but we always recommend taking HVAC maintenance advice from a professional. Every HVAC system is different; something that works great for one system could be detrimental to yours.

3 Signs of a Faulty Furnace Gas Valve

A furnace gas valve allows natural gas or propane to flow into your unit. Occasionally these valves will stop opening and closing properly due to an obstruction, rust, or old age. If this valve malfunctions, it could be a hazard to your health and home as gas or propane will freely flow from the furnace without combustion.

Below are the 3 common signs of a faulty furnace gas valve to keep an eye out for as a faulty valve could be creating an unsafe environment. When in doubt, always call an HVAC professional.

FYI: When the valve stops working, it needs to be replaced as a repair is often more costly than a replacement. Typically, a gas valve replacement costs anywhere between $400 and $1000, making it one of the most expensive parts in a furnace to replace.

Gas leak

Sometimes a gas valve will get stuck open, allowing too much gas into your furnace while it is running, or allow gas to leak into your furnace while not running. Not only is this gas a fire hazard, but inhaling gas is very bad for your health. If you smell gas in your home, open your windows, exit your home, and call 911 immediately.

System failure

If your furnace is not heating your home or having trouble starting, this could mean your gas valve has malfunctioned and is not supplying enough—if any—gas to the unit. This means the ignitor will not work, your furnace will not be transferring any heat, and the system will stop blowing warm air. If the furnace is not running or it is not blowing warm air, call for a repair.

Though a system failure could be the result of a faulty furnace gas valve, there are many other possible culprits. If your unit is not blowing warm air, there are many other possible causes. Click here to learn more.

Furnace cycling

Similar to a system failure, when your furnace does not receive enough gas, it may continuously cycle to try to reach the temperature set on your thermostat. When the thermostat does not read the correct temperature, it will continue to tell the furnace to run. Regardless of the cause, a constantly cycling furnace could result in an overheated blower motor or other avoidable repair. If your furnace is cycling, shut the unit off and call for a repair.
