Best heating and cooling systems for older homes

Older homes are more difficult to both heat and cool. Their structural differences make it more challenging, but that doesn’t mean you have to spend more money to keep your home warm during the winter and cool in the summer. There are plenty of HVAC options available for your older house to maintain a satisfactory temperature all year long. Here are options for the best way…

Best Way to Cool Old Houses

Some older homes were made long before there was ever even such a thing as air conditioning. As a result, many houses don’t have the proper ductwork required to handle the modern air conditioning systems that are so popular today. Due to this issue, older homes are not the best for central air conditioning.

However, there are still other options available for cooling older homes. These are not only energy-efficient but can also provide heating to your home as well. The following are two common, popular options:

• High-Velocity HVAC Systems

  • In most cases, the ductwork in a house is tucked away in some remote location that you can’t see. In older homes that were not built to accommodate central air conditioning systems, there may not be sufficient space to install the right ductwork to accommodate this type of HVAC system. A high-velocity HVAC system is a good alternative as it uses a unit that connects with a miniature duct system to deliver cooling — and heating during the winter — throughout the entire house. Miniature duct systems are smaller than traditional ductwork, which means they are more accommodating and can more easily be added. They are only around three inches in diameter, allowing them to be used over the ceiling and walls for installation. Vents are also smaller, which means they are less visible and invasive.

• Ductless Mini-Split HVAC

  • Another option that works for older homes is a ductless mini-split HVAC system. This setup doesn’t require any ductwork installation but uses an exterior heat pump that connects to interior units that can then deliver cooler air to the rooms that need it. The same can be said for heat during the winter. The components of this setup connect through a hall in the exterior walls of the house. The interior parts of the unit can be installed either high or low on a wall or on the ceiling and controlled with a remote. In each room, the occupant can independently control the temperature they want. Meanwhile, unused rooms don’t get any cooling or heating, which saves you both money and energy.

Best Way to Heat Old Houses

The options mentioned above are great for not only cooling but heating older homes. You can also get heating from radiators. Many old houses already have this type of heating system, which first became popular in the 18th century. However, you may want to upgrade your old radiators to more energy-efficient options. Consulting with an HVAC professional is wise as they can come to your home to inspect your system and determine what might require upgrades and what can remain. In most cases, older homes do well with individual radiators in each room while a new boiler is installed to deliver warm temperatures throughout the house.

A modulating condensing boiler may be the best option for a hot water heating system. They are more energy-efficient due to heating only the amount of water needed to heat the home instead of heating all at once. You can enjoy better comfort during the colder days of the year and enjoy cheaper energy bills at the same time.

There has always been conflict and difference of opinion about making changes to an old house, and for good reason. There is a delicate balance between preserving the historical integrity of a home and making upgrades to support the demands of modern life. One of the most important considerations in this regard is how to heat and cool the house.

What You Need to Know About Older Homes & Energy Efficiency

Before jumping on to how to cool or heat your old house, you should first focus on how to make your home more energy efficient. Old houses have significant structural differences from newer homes, which are built by modern energy efficiency standards. While the average new home today may have things like tightly sealed doors and windows, weather-stripping, and sophisticated ventilation systems to control indoor temperatures and humidity levels, older homes won\’t have these systems in place. This means that older homes have more problems with air leakage, translating to heat loss during the winter and cold air loss during the summer. This, in turn, means more work for your heating and cooling systems and more money spent on trying to control your indoor temperature. Correcting energy efficiency issues can help you save!

Here are some things you can do to improve the energy efficiency of your old house:

• Install a smart meter. Installing a smart meter in your home will help you keep track of your energy consumption. 
• Update lights. Swap out traditional light bulbs with energy-efficient and long-lasting LED bulbs. Not only do they consume very little energy and last up to 25,000 hours, they also provide the added bonus of emitting less heat than older bulbs that range from 100 watts to 1000 watts. 
• Get a smart thermostat. Smart thermostats are programmable, which means you can customize your heating and cooling preferences for different hours of the day without having to constantly change the settings. For example, you can set the temperature lower during the hours you\’re away at work, which means you\’ll save more on the energy that would have been wasted before on heating or cooling an empty house.
• Consider renewable energy. Using renewable energy to generate electricity will help you save money on your electricity bills, but it may not fit the aesthetic of your home if you\’re trying to preserve its historical integrity. If this isn\’t a problem for you, solar panels are a great option.
• Address your chimney. The chimneys in houses built decades ago were built with different requirements than today, which unfortunately means that in addition to a number of safety concerns, they are also a prime place for heat/energy loss. Always keep the damper closed when the chimney is not in use. You may also wish to consider hiring a chimney professional for an inspection and to go over additional options on how to keep energy loss to a minimum.

How to Cool an Old House

Most old houses were built even before the concept of air conditioners entered the market. As a result, they aren’t compatible with modern air conditioning needs, like a duct system to circulate air throughout the home. If your old house doesn\’t have air ducts, don\’t worry; you still have options!

If you are looking for the most economical way to cool your old house, consider the following:

High-Velocity HVAC Systems

Even if you wanted to install ductwork for central air conditioning in an old house, it simply may not have the space to accommodate it. While this may seem like an obstacle, it may actually be a blessing in disguise, because there is a better and more cost-effective solution. Rather than spending several thousand dollars trying to add conventional air ducts for central air conditioning, you can go with a high-velocity HVAC system instead. High-velocity HVAC systems use mini-ducts that are considerably smaller than the standard ones. Since they are small, they can be easily installed around the house. They even have smaller vents, which means fewer disruptions to the interior decoration of your house. 

Ductless Mini-Split Systems

Another potential solution to solve the ductwork problem is to get a ductless mini-split HVAC system. As the name suggests, they do not require ductwork installation. Instead, mini-splits utilize two main components: an outdoor compressor and an indoor air-handling unit, which are linked together by a conduit housing the power cable, refrigerant tubing, suction tubing, and a condensate drain. This system offers balanced conditioned air around the house as well as zoning capabilities that can help you save money.

How to Heat an Old House

As with air conditioning, a lack of air ducts is the biggest consideration when choosing ways to heat an old house. If you\’re in this situation, here are some heating systems that will work for your older home:

Mini-Duct Forced Air System

If you\’re looking for an easy HVAC retrofit for old houses. the mini-duct forced air system might be for you. Also known as a small-duct high-velocity HVAC system, a mini-duct air distribution system, or a Unico system, it\’s one of the best and most versatile solutions for heating an older home. Other benefits include whisper-quiet operation and unobtrusive outlet vents that won\’t disrupt your home\’s aesthetics.

Radiant Heat

Radiant heating is a concept that became popular post-World War II. Unlike forced air heating systems like furnaces or heat pumps, radiant heating systems involve the use of hot water pipes that run underneath your flooring. Radiant heat is often found in old houses, but they may be prone to leaks. To avoid problems, you should have your system routinely maintained by a qualified heating professional. If you ever see evidence of a leak, call for service quickly to keep flooring damage to a minimum.
