Air Conditioning Services FAQs

Curious about our AC services? We have a few questions that we encounter often here at SM Mechanical — Connecticut’s source for AC repairs and maintenance services. That’s why we’ve cataloged a few of our most frequently asked questions below. If you don’t find the answers that you need right here, you can always reach out to us for more information!

Why isn’t my air conditioner working?

If your air conditioner isn’t operating you could have any number of problems that are to blame. For instance, you may have an electrical problem that is preventing your air conditioner from clicking on. Or, you may have a thermometer that is poorly calibrated, which means that your unit won’t turn on when it should. You may also have a frozen evaporator coil (which cools the air that pumps through your home) which will reduce the efficiency of your AC unit and damage its components. You may also have a broken fan, or you may have a clogged air filter, among other issues. When you notice that your home won’t remain at a cool temperature through the warmest months of the year, we can take a look at your AC unit and ventilation to assess the source of the problem — and then we’ll get to work fixing your cooling system right away. Just reach out to us or get a quick, free quote in a few clicks to get started.

How long does a typical AC unit last?

Most air conditioner units tend to last between 10 and 15 years. That said, your air conditioner may last shorter or longer depending on the model that you have, how well you maintain the unit, and how often your unit clicks on during the summer months. If you think you need to replace your AC unit, you can learn more about our AC installation services, or you can give us a call with any questions that you may have.

My AC unit isn’t working — should I repair or replace my AC?

That depends. If you have a relatively new AC unit, it may be cost effective to simply fix a small malfunction — since your unit will likely continue to run for years on end. On the other hand, if you have a unit that is fairly old, and it has broken down or it is inefficient, it may be best to swap out your unit for a new model. For some repairs, like a broken fan, your unit can be repaired fairly inexpensively, while other repairs, like a compressor failure, can cost nearly as much as an entirely new unit. If you’re curious about the best option for your particular issue, we can diagnose the problem at hand, and we’ll let you know what makes the most sense for your specific scenario.

How can I reduce my home cooling costs?

Improving the efficiency of your home and its AC unit can save you hundreds of dollars in the long run. If you’re looking to improve the performance of your AC unit and the efficiency of your abode, follow these tips:

  • Invest in insulation: Your home’s insulation is its defense against hot air in the summer. Insulation slows the heat gain between your walls and the interior and exterior of your home. If you have poor insulation, heat will make its way into your home, no problem. You may be able to retrofit your home with better insulation (like spray-in insulation) that will improve its efficiency.
  • Update your windows and doors: Your doors and windows are weak points for the efficiency of your home. If you have outdated or poor-quality windows and doors, then heat may be seeping in. Invest in doors and windows with a high R-value (a number which represents how well a material resists heat transfer). You can find thick doors with built-in insulation and multi-pane windows with high R-values.
  • Recaulk seams throughout your home: While you’re looking at the doors and windows of your home, it’s a good time to check the caulking around these weak points. Make sure there is a thick, intact layer of caulking around the interior and exterior edges of your windows and doors. Caulking ensures that your seams are sealed, keeping hot air from flowing into your home during the warm months of the year.
  • Keep new filters in your AC system: Your air filter captures particles that you don’t want to have in your home. However, over time these particles will build up and restrict the airflow into your home, which means that cool air won’t pump into your abode. Invest in new air filters when your old filters get gunked up, it’s worth the small cost of a filter to reduce those energy bills.
  • Maintain your air conditioner: Your air conditioner is made out of a variety of components and moving parts. As such, any wear and tear can prove to make these parts inefficient. With regular AC maintenance, you can keep those moving parts operating smoothly, so that your unit runs effortlessly. We recommend a scheduled maintenance program for your air conditioner at least once per year. With all of our maintenance service calls, we provide a thorough cleaning of your AC unit, a thermostat calibration, we replace air filters, we tighten component connections, we lubricate the motors of your unit, and we test your system — thus improving the longevity and efficiency of your machine.
  • Consider upgrading your AC unit: If you have high energy costs, you could have an air conditioner that is poorly suited for your house. Oftentimes, folks have AC units that are too small for their home, and these units have to run constantly as they try to keep the air consistently cool. Ideally, your AC unit won’t turn on more than three or four times in an hour. If it remains on, or it turns on more often than that, then your unit may be too small. If you need to pull out your current unit and install a new AC unit, we can help.

How much does a new air conditioner cost?

Again, costs can vary vastly, depending on the size of the unit, the model of the unit, and additional factors surrounding the installation of the unit. That said, most air conditioner installations will cost between $500 (for small units) and $4,000 (for larger, whole-home forced central air units).
