Maintenance and Repairs

To keep your air conditioner units in working and tip-top condition, regular maintenance and repairs are sometimes needed. Before you decide to call a serviceman, here are some things you can do on your own to make your conditioner perform well.

Clean or Replace Your Filters

One of the most important things you can do is clean or replace the filter for your unit. Filters should be replaced or cleaned at least once a month. If you’re having difficulty picking a filter, you can contact your Lennox dealer to assist you with picking the right one.

If your air conditioning unit is in constant use or there is a lot of dust in your home, your filters will need more attention.

Clean the Coils

Over time, your air conditioning unit’s coils will collect dust. The more dirt and dust your coil collects, the more airflow and insulation will reduce. To keep from blocking airflow, you should remove anything blocking your unit.

Remove Any Debris From Your Unit

Dirt, debris, and other particles can collect on the outside of your unit and decrease the airflow. Make sure you trim back any plants that could be blocking your unit.

Straighten the Coil Fins

On your unit, the coils can easily become bent and can block the air from flowing to your coil. Have your Lennox dealer check them regularly and straighten them out if needed. 

To find parts for your product, Lennox offers a repair part finder on its website. This allows customers to manage their time more efficiently and find the parts that they need. You can operate their service on your phone, tablet, or desktop.

You can search for your Lennox parts using their catalog number. Four search options you have include the model/part number, serial number, and catalog number. Lennox also has a Top 5 Replacement Carousel Feature.

This feature allows you to order any needed extras if you end up having a service call with a similar problem. This will not only save customers time but money.


When installed by a professional, Lennox has been a go-to for companies to use for heating and cooling. Companies install a wide range of their products because they are reliable, high-performing, and energy-efficient. If you’re not a registered professional, installing an air conditioner could seem like a tough job.

For most homes, customers choose a split-system air conditioner. These units consist of an indoor unit, a fan, and an outdoor unit. The indoor portion will be mounted on the wall, while the outdoor unit is installed on the surface level.

Before a professional can install your unit, they must know if you have an old system before you replace it with a new system. In addition, you might need to give them info such as the requirements and job that needs to be completed.

For a professional, the installation process is fairly simple. Please keep in mind that you should never try to install a home air conditioning unit on your own.


When it comes to home air conditioning and heating, Lennox systems cost the most. Prices for their products will range anywhere from $3,000 to $7,500 depending on the product and its size. Even with their high prices, the company has a great reputation for supplying high-quality products to its customers.

When compared to other companies, Lennox will give their customers more money in savings, which makes it worth it to pay the high price. Lennox does not give the prices of their products on their website, they will only be given over the phone to their customers.

They do not provide the prices because their products are only installed by Lennox dealers. For a customer to get pricing for a product, they must call a Lennox dealer to receive a quote. The price of your unit will depend on the size, age of your home, home design, local climate, and condition of the ductwork.

Maintenance and Repairs

During those hot summer months, air conditioners provide relief from the humidity. When running smoothly, air conditioners can be a great thing. However, when the temperature increases outside, this can cause the humidity to rise inside and put stress on your unit.

Air conditioner maintenance and repairs are a must in having your AC unit runniung smoothly. You should have your AC unit serviced by a technician at least once a year. Parts such as your coil and filter require maintenance to run efficiently.

When scheduling regular maintenance for your unit, this can help extend the life of your AC unit. If you have a cooling unit, several factors may determine it’s time for an AC repair. Some of these factors include running constantly, repeated starting and stopping, weak airflow, or high energy bills.

If you need new parts for your unit, you can go to the HVAC Direct website. Some of the parts they carried are circuit boards, heat exchangers, motor and motor parts, pilots and ignition, sensors, switches, valves, and other miscellaneous parts. If you don’t see what you need on their website, you can fill out a request form so they can track down exactly what you’re looking for.


When installing a new air conditioning unit in your home, the easiest way to make the installation process go smoothly is to call a technician. You never want to try and install an AC unit on your own. During installation, you’ll never know if you need to replace your unit or have an entire system installed.

Are you purchasing a forced-air split system or a geothermal system? These are questions that only a trained technician would be able to answer and to find out which one is right for your home during installation. The most-basic installation can take anywhere from 4-8 hours to install.

If your outdoor unit and your indoor unit need to be installed, you’re looking at around 8-14 hours. The more time it takes to install your unit, the higher the installation costs will be. Installation costs can cost you anywhere from $3,000 to $15,000.


When purchasing an air conditioning unit, the cost will depend on the size and model type. The best way for you to determine how much your unit is going to cost is to contact your Carrier dealer. For air conditioners, you can expect to pay anywhere from $3,000 to $15,000 with installation included.

For ductless mini splits, you can expect to pay anywhere from $2,000-$10,500 with installation included. For geothermal systems, you can expect to pay anywhere from $12,000-$45,000 with installation included.

When determining the price, there are always factors you’ll need to take into consideration. Do you want a basic unit installed or are you looking for a luxury model? Are you looking for a model that has a high SEER rating?

Are you looking for a model that provides large amounts of savings in energy? These are all questions that will determine the price you end up paying for your unit.
