If you’re faced with a Minisplit that is flashing an error code at you and you’re unsure how to determine what the code is or what to do here’s how to tell if it’s actually normal flashing.
Right now with the cold winter temperatures and the freezing rain and snow and sleet and driving winds that we have been receiving here in our area it’s been putting a tremendous amount of stress on the heat pumps as they try to produce heat for your home because the outdoor condensing unit is located outside and in some cases is not protected from these types of elements.
Above is a good example of an install that is protected from the home yet is still far enough away from the house to allow for proper airflow behind the machine which is wheddsd
If you have only one single flashing light at you and it is steady and constant this might be a defrost mode.
Defrost mode occurs as part of normal operation when the coil outside gets too cold the outdoor condensing unit stops and send a signal inside to have the fan slow down sometimes the fins will close up and the light will start the flash to indicate the unit is in defrost mode outside this might be in the state for 6-8 minutes.
During the 24 hour period you may not notice but the unit could do this maybe four times a day or more.
In this article, we’ll discuss what heat pump & mini-split systems are, how to choose the best installer, and tips for ensuring your installation goes smoothly. What Are Heat Pump / Mini-Split Systems? A Heat Pump is: Heat pumps run on electricity and refrigerant much like a traditional HVAC cooling system, but the process is reversed thereby creating heat in addition to cool. These systems routinely heat 3X more efficiently than traditional oil systems and are ⅔ more efficient than a window AC—creating a return on investment in all seasons. A Mini-Split system is a ductless type of heat pump—a ductless heating and cooling system powered by electricity. The system is designed to provide an efficient and environmentally friendly way to regulate temperature in specific areas of a building. Unlike traditional HVAC systems, mini-splits don’t require ductwork, making them an ideal solution for: Homes without existing ducts Those looking to add heating or cooling to individual rooms Additionally, mini-splits release upwards of 3.6x fewer GreenHouse Gasses than traditional HVAC Systems, making them the environmentally conscious choice. These systems consist of two main components: Outdoor Unit (Compressor) Indoor Units (Air Handlers or Mini Splits) The indoor units are mounted on the wall or ceiling and are connected to the outdoor unit using small refrigerant and power lines. Key Benefits: Energy Efficiency Individual Room Temperature Control Discreet Design: Some indoor models double as picture frames Neutral Color Options to blend into surroundings Incentives: Massachusetts offers up to $10,000 in direct rebates Federal Government provides up to $2,000 in Inflation Reduction Act credits Why You Need a Professional Mini-Split Installer Choosing the right installer for your heat pump heating and cooling system is the most important decision you'll make on your mini split or ducted heat pump installation project. Benefits of Professional Installation: Correct Sizing: A proper installer ensures the system is the right size. Undersized = poor performance. Oversized = inefficiency and higher costs. Proper Placement: Technicians know the optimal indoor/outdoor unit locations for performance, airflow, and minimal noise. Compliance with Codes: Professionals ensure your system meets local building codes and safety standards. Warranty Protection: Many manufacturers require professional installation for warranties (often 10–12 years). Troubleshooting and Setup: Expert installers calibrate your system, resolve issues, and show you how to maintain and use it efficiently. How to Pick the Best Mini Split Installer Selecting a reliable, experienced, and certified installer is key to ensuring a successful installation. 1. Experience and Reputation Experience is the single most vital factor. Look for: A proven track record Familiarity with mini-split systems Knowledge of seasonal settings and energy savings Check: Online reviews References Better Business Bureau (BBB) Ask friends or family—and look for referral discounts 2. Review Quotes Quotes should include: Labor Equipment Materials Time estimate A reputable installer provides clear pricing with no hidden fees. Be cautious of quotes that are too low. 3. Consider the System’s Warranty and Any Maintenance Good installers offer: Ongoing support Workmanship warranties Manufacturer coverage Optional 100% satisfaction guarantees Red Flags to Watch Out For 1. Unlicensed or Uninsured Installers This could lead to: Poor quality work Fines or removal of equipment Always check for: EPA Clean Air Section 608 HVAC Certification Proper permits from local planning/building departments 2. No References or Reviews Lack of experience can equal poor results. 3. Lack of Transparency / Pushy Sales Tactics Avoid installers who: Are vague about pricing Can’t explain the process Pressure you into quick decisions Final Thoughts A mini-split system is an excellent investment in home comfort, but choosing the right installer is key to a smooth, successful installation. By selecting a licensed, experienced, and reputable installer, you’ll ensure your system is properly installed and performs well for years to come—providing both comfort and energy savings. Take your time, ask questions, and choose a professional who can guide you through the process and provide ongoing support.

It’s time to replace that aging furnace, inefficient HVAC equipment or simply add a primary source of heating and cooling to your home that is 3-4 times more efficient. Heat Pumps provide both heating and cooling to your home and are more efficient than an old fuel burning furnace. Now you can provide heating and cooling to your home with more efficient equipment, saving you money, and making the environment and your home safer by eliminating fuel emissions which means cleaner air for both the environment and the inside of your home. Turning to heat pumps means you will have more control over the temperatures of the different parts of your home and you will have greater flexibility to provide heating and cooling to those areas of your home that were previously had problems with under heating or under cooling. So rather than making the entire home one temperature, you have the flexibility to individually control the temperature of each living space to the perfect temperature. The heat pump compressors are variable-speed and reduce energy consumption compared to conventional systems by up to 40% Heat pumps run on electricity so they do not burn fossil fuels which is far better for the environment and most Heat Pumps have an Energy Star rating. A Seasonal Energy Efficiency Rating SEER and other scientific evidence to prove that heat pumps are the energy source of the future for residential and commercial environments.

A heat pump is able to transfer thermal energy from inside to outside and also from outside to inside. A heat pump works as an air conditioner by transferring heat from inside to outside. Heat pumps can also be used for heating. When heat pumps are used to heat a building the energy or heat is transferred from outside to inside. Mini Splits are commonly ductless and for this and other various reasons they are highly efficient and rely on electricity to provide heating and cooling thereby reducing the demand on fossil fuels. Typically it has been measured that 1kWh of electricity can transfer 3-6 kWh of thermal energy into a building, this is amazing and highly efficient as opposed to an oil boiler or a window AC unit both of which minisplits are 3-4 times more efficient over. Heat pumps are filled with refrigerant, this gas/liquid is highly controlled by the EPA and you must be licensed by the EPA to purchase and handle the current models on the market. Most of todays heat pumps are currently working with 410-a refrigerant. The heat pumps produce heat by taking the liquid outside and compressing it, making it hot. This hot liquid is transferred inside through a series of copper tubing that must connect the indoor and outdoor units. This hot liquid passes though a coil and is blown with or without ductwork. To cool your home, the heat pump works in the opposite, by compressing the indoor hot liquid and sending it outside to be cooled by the large coil and fan at the outdoor compressor. It is possible that heat pumps could be used in the future to replace most oil and gas fired heating equipment to create a lower carbon footprint. Air sourced heat pump minisplits are relatively inexpensive to install and historically have been the most widely used type of heat pump, modern heat pumps with a low temperature designation are able to provide heat inside your home even when the outdoor temperatures reach down to -15 degrees. In traditional air sourced heat pump systems, the system has a vapor compression device, a compressor and the system includes a reversing valve so that the direction of thermal energy, heat, or cooling, can be reversed. The energy efficiency of a heat pump is measured in SEER – Seasonal Energy Efficiency Rating a heat pump must meet a SEER rating of 14.5 to qualify for an Energy Star rating.
