As the temperatures rise, you need to start thinking about getting an HVAC technician at your home to make sure your air conditioning unit is working properly. If your unit isn't operating as it should, you'll end up with warm air filtering through your home, leaving you uncomfortable and sweaty. Or, you'll have an AC unit that doesn't work at all and you'll be left with repairs while the sun is glaringly hot outside.

Whether you own a swamp cooler, central air system, or a classic window air conditioner, you need to get a specialist to your home to make sure your unit is working right. What air conditioning services do you need? Use this guide to help you.

New hoses

If your AC hoses are leaking or pinched, then you want new hoses put in. These hoses are mostly used in swamp coolers to allow water to filter through the unit and keep air cool and prevent the fan from overheating and breaking. Have hoses checked and replaced by your HVAC specialist as needed.

New filters

Air filters are placed in your air conditioner, swamp cooler, or outdoor HVAC unit to allow the debris from outside air to be caught and kept from getting inside your home. You want clean air to keep pollen, dust, hair, and other allergens at bay. You should have these air filters replaced or at least cleaned every season (or as per your unit's instructions), particularly if anyone in your home suffers from allergies or asthma.

New pump

Some home cooling systems, particularly swamp coolers, use pumps to help filter water and keep air flowing. If your pump dries out or runs hot, then you may need to have this unit repaired. Along with the pump, compressors and fans will need to be checked to make sure everything is working as it should.

Often, if one part of a cooling unit goes out, others are affected as a result. If your air conditioner starts to overheat, release warm or hot air, smells of smoke when operating, or becomes hot to the touch, stop using the unit and call for emergency repair services. Your air conditioning unit may need to be replaced to best meet your needs, so discuss your budget with your contractor before you begin the repair process to see if getting a new unit or repairing what you have is a better option.
