It’s never recommended that a homeowner attempt AC repair on their own, as air conditioners are often far more complicated than they realize. Today’s models are also especially technical, often with computer chips and other parts control digital readouts, built-in dehumidifiers, and similar features.
Simple AC repair includes changing the furnace filter, cleaning the grille around the AC condenser, and checking the fan blades and drip tube for any obstruction. A home’s thermostat might also need recalibrating or new wiring.
To help you through this process, you might note some simple AC repair troubleshooting tips. Some fixes you might address on your own but consider calling a heating and cooling company near you for complicated repairs. It’s also good to note if DIY repairs might void a warranty on your home’s air conditioning unit!
When performing any fixes around your home, first be sure you use all needed safety precautions! Shut off circuit breakers, wear protective gloves and eyewear, and keep children and pets away from your work area. If you’ll be using any aerosol sprays, such as lubricants or cleansers, wear proper breathing apparatus and ensure your home is well-ventilated.
If you try all these quick fixes and your home’s air conditioner doesn’t cycle back on or cool your house adequately, it’s probably time to call an air conditioning repair contractor near you.
An air conditioner refusing to cycle on is not the only sign of needed AC repair! The sooner you schedule needed repairs, the less risk of continued damage to your unit, so note some signs that it’s time to call an AC contractor near you.
While a home’s AC unit might struggle to work as it should during overly warm and humid summer days, don’t overlook any of these signs of needed repairs, or of an air conditioner that simply doesn’t cool your home as it should. Timely repairs reduce the risk of those fixes getting more extensive, and more expensive, over time.
In some cases, an air conditioner is simply beyond repair and needs replacement. How do you decide when it’s time to get a new AC unit, or when does a heating and cooling contractor normally advise an AC installation or replacement versus repairs?
One consideration is your expected repair bill and if more parts are sure to break down in the next few months or year! If your immediate repairs, and repairs you’ll face in the next year, are close to the price of a new AC unit, it’s good to simply invest in that replacement air conditioner.
Many older air conditioners are also very inefficient, meaning a large percentage of the energy they draw is used to run the unit’s internal parts and not for actual cooling! An upgraded energy-efficient unit might result in lower utility bills throughout the year.
An undersized air conditioner might also struggle to cool your entire home so that some rooms always seem hot and stuffy. An oversized unit might also offer too much power for your home so that you’re simply wasting electricity. Replacing your air conditioner with a properly sized unit for your home means consistent, even cooling and no wasted energy.
Regular AC maintenance is an excellent choice for keeping your residential furnace and air conditioner in good repair and for avoiding otherwise unnecessary breakdown. Standard AC maintenance typically includes a good cleaning, removing dust and dirt from inside parts as well as debris from around the compressor housing.
An AC contractor might oil moving parts, check belts and hoses for signs of wear, and look for rust around connectors and other such parts. Wires are checked for wear and the thermostat also tested and calibrated as needed. Drainage hoses are also checked and cleaned. Refrigerant levels are checked and the unit inspected for leaks, and airflow through the evaporator checked as well.
Your air conditioner contractor often makes minor repairs during this maintenance check, replacing belts, tightening connectors, and applying nonconductive coatings if necessary. These simple fixes help avoid major repair bills down the road, and keep your air conditioner functioning properly and efficiently.
How much does AC repair cost?
Many AC repair contractors charge by the hour, often between $75 and $150, while some will offer a flat fee for certain repairs, such as replacing a damaged motor. If you’re not sure the repairs needed, be prepared to pay an hourly fee or a small flat fee for an inspection, and then a quote for needed repairs.
Why does an AC run but not cool the house?
If your AC is running but not cooling the house, it might need a recharge of refrigerant and repair to the compressor or hose containing the refrigerant. The thermostat might also need calibrating. Your contractor can note needed AC repairs for a unit that cycles on but doesn’t cool.
