A: There are many reasons why your AC unit is freezing. Low refrigerant, dirty evaporator coils, a faulty blower motor or relay, even a dirty air filter or a combination of these issues could freeze any air conditioner. Turn off your system and allow it a few hours to thaw completely. Once the ice is all melted, change out the air filter and turn the system back on. If it freezes again, call us and we’ll send a technician to provide a diagnostics.
Because the air conditioning and heating systems of today are so technologically advanced and efficient, you should consider replacing the system if it is outdated. Current systems are more durable and efficient than heating and AC units from even 10 years ago. For example, if you just bought an old house and the HVAC system is from the 70s, you’re likely to be more comfortable knowing that you have an up-to-date system to rely on throughout the upcoming years.
If your old heating or cooling unit is experiencing problems with efficiency and driving your heating and cooling costs up, it may be time to consider getting a new system.
Call New Hope Heating and Air Conditioning. We offer many financing options to help you afford a new system. We can also run a diagnostics and repair the system if less expensive than replacement.
It’s a good rule of thumb to schedule maintenance at least once annually. To get the best results, schedule maintenance twice yearly: once in the months before summer and again before the winter months. As for why, regular HVAC maintenance helps you catch problems before they turn into expensive repairs, and ensures that your system is running at peak efficiency. Regularly scheduled maintenance also helps prolong the life of the unit, allowing you to get the most from your investment.
While most maintenance should be performed by an HVAC technician, one of the best things you can do to keep your HVAC system performing in tip-top shape is to keep your furnace clean. Change your filters and make sure nothing is blocking your condensers in order to ensure proper ventilation. Also, make sure your pets aren’t urinating on or near the unit to prevent expensive damage.
Comfortable humidity in homes average from 30 to 35 percent. When you open and close doors and windows, cool and moist outdoor air enters your home and dries as it warms up. This can create issues with static electricity build-up and sinus problems. A humidifier can help balance out the moisture in the home and help minimize these problems during the dry winter months. Factors such as home layout, how often outside air circulates indoors, the size and style of humidifier can affect humidity levels.
For the best performance and efficiency, change your filters at least monthly, depending on your furnace and how heavily you use your system.
HVAC systems these days are built with efficiency and durability in mind. If [installed properly by a qualified technician,] you should expect your new air conditioner or heater to last at least 10 to 15 years or more. It can last even longer with [proper maintenance.]
It depends on your priorities. There are pros and cons to both the ON and AUTO function of your heater and AC. If you’re home and you want a more consistent temperature, the ON function is best because the fan will consistently blow the heat or AC through your home. If the home will be vacant, but you still want to experience some comfort when you do come home, the AUTO function is best. Your AC or heater will continue to run until your space has reached its set temperature.
If you use the ON function often, you’ll have to change the filters in your house more frequently, and your bill will be more expensive. Using the AUTO function will save you some money on your bill and on filters.
