As early as the first week of March there are things you need to consider doing in order to make sure your central AC is ready for the heat of summer. Depending on where you live, you may actually find that your HVAC system works harder during the warmest months of the year than it ever did during the winter, so it's worth investing some time to ensure it can keep up. As unpleasant as it might seem to spend a few days without heat, it's far worse and far more dangerous to have your AC go out during the hottest months. At least in the winter you can put on additional layers.
Even before you feel like you're going to need your AC it's a good idea to have a professional, from a location like Plisko Electric, check it for faults, failures or problems that could require repairs. An inspection should include any exterior components, such as the compressor where cool air is produced, as well as interior components such as the forced air system, which supplies each room. Further checks and cleaning of the ventilation ducts should also take place to ensure no holes have developed and that there isn't anything constricting air flow.
HVAC companies often have a jump in business during the hottest parts of the summer, when emergency calls happen most frequently. Taking care of potential problems before they pose a health risk can avoid the cost associated with high priority repair calls. Better still, you'll have the confidence of knowing that your AC is blowing clean, cool and consistently throughout your home when you first switch it on.
Apart from cleaning the ducts there are also some other maintenance tasks that need to be attended to in order to ensure your AC works when you need it to. Compressor fins should be cleaned and kept clear of the expanse of nearby foliage, such as grass or shrubbery. The system's Freon levels should also be checked and topped off as needed to ensure that you're not wasting energy by cycling your AC on and off more frequently than you should need to.
The exterior compressor component of your central AC system relies on the compression of Freon gas in order to exchange heat. Expansion fins inside your home and inside the exterior compressor allow heat to be exchanged, cooling the air as the gas expands and contracts. Dirt, debris, or other obstructions will impede this process, so it's a good idea to clean them off regularly and make sure to keep the area mowed or pruned, as appropriate.
It's far better to put a little effort into maintenance and upkeep than to end up sweltering in July while you wait for a repair appointment. Getting the jump on the summer early will ensure you spend it in comfort rather than misery.
