    Can Your HVAC Be Repaired?

    Just because your air conditioner doesn’t work doesn’t mean it needs to be replaced. Air conditioners have a lot of moving parts that work together in order to make it run smoothly. If your air conditioner stops working, the best thing to do is to call a licensed professional to see if your air conditioner can be repaired before you start worrying about replacing the entire unit.

    Sometimes, the system just needs a small part. There are others when there are obstructions (like packrat nests) that have caused issues that have nothing to do with the actual air conditioner itself. So if you find that your air conditioner is not working the way it should, a professional can diagnose what may be causing the problem and provide a solution; many times, without having to replace the unit itself. AC repair can be done easily by Cummings Plumbing Heating & Cooling

    How Often Should You Have Your HVAC Looked At?

    Most people aren’t sure how often they should have their air conditioner looked at. If you have a heating and cooling unit combo (which most people do) we recommend twice a year. You’ll want your air conditioner looked at during the spring before summer starts and your heating system looked at before fall starts. Of course, it’s always best to have your system looked at before you plan to use it.

    Each system has its own list of items that a technician should be checking for. During this process, the technician should also do any routine repairs and maintenance to your air conditioner that is needed and inform you of any upcoming issues. A good technician will also let you know about the lifespan of your air conditioner so that you can plan accordingly, should you need to start preparing financially for a replacement unit.
