Common Problems with Newer Central AC Units

If you are dealing with any of the below issues, call our Plano AC repair specialists to discover how we can help you get your air conditioner back up and running quickly.

Why Is My New AC Not Working?

  • Improper sizing of unit to home: It’s not uncommon for an AC unit to be too small for a large, new home. Smaller units cost less for developers to install yet often aren’t large enough to cool down a home with high square footage.
  • Bad wiring: Depending on the home builder and AC contractor, uncertified technicians could have installed faulty wiring which can trip the circuit breaker and is a fire hazard.
  • Inadequate Testing: Many new home AC systems aren’t tested properly in respect to the entire central air system including the AC unit, air ducts, and thermostats. Inadequate testing could lead to an AC system that is set up for failure in the long run.

Common Problems with Old Residential AC Systems

Plano also has a large number of existing homes and businesses. Problems with old AC units are far different from new units.

Issues Our Plano AC Repair Team Can Resolve:

  • Refrigerant leaks: AC units low on refrigerant could be experiencing a leak. Realize adding more refrigerant does not solve the underlying problem. Contact our Plano AC repair experts to fix the leak and add more coolant.
  • AC Fan or Compressor failure: Common with old systems, these are critical and costly parts that eventually break down. A repair could solve the issue, but it is more costly than a full AC replacement.
  • Frozen inside air coil: Air coils that freeze are often caused by dirty filters or blocked air ducts. Unless your AC system is regularly being maintained, repairs and breakdowns for frozen air coils are likely to occur. Learn more about our active maintenance programs.

How to Determine When it’s Time for AC Replacement

Most homeowners have paid a lot of money for their home’s air conditioning system. It only makes sense to want to get the most out of that system. The longer the HVAC system lasts; the greater the ROI. Unfortunately, all good things come to an end. AC units can last for many years, but eventually, they’ll need to replaced. Fortunately, you can watch for some simple signs, which indicate the need for replacement.

When to Replace Your Air Conditioner:

  • Your AC system has a SEER rating that is less than 13. Systems that have a SEER rating less than 13 are using too much energy and costing you money. By having your AC system replaced, you can help the environment and pay less money for energy.

  • Your air conditioning system is 15 years or older. On average, AC systems have a lifespan of about 15 to 20 years. However, to continue operating for 15 to 20 years, air conditioners must receive proper maintenance.

  • Your air conditioning system uses R22 refrigerant. New regulations prevent the use of R22 refrigerant. Unfortunately, this type of refrigerant has a negative impact on the environment. By having your current R22-based system replaced, you can save money and help protect the environment.

  • You notice an increase in your energy bill. If a unit is receiving proper maintenance, it shouldn’t cause the energy bill to rise every month. If your energy bill is continuing to skyrocket, it could be a sign that you need to have your air conditioning system replaced.

  • Your home is less comfortable. The purpose of an air conditioning system is to make a home comfortable. It filters air and maintains a comfortable temperature. If you find hot or cold spots throughout their home you should consider getting your AC system replaced. However, before having the system completely replaced, it’s important to make sure it’s getting proper filter changes and similar maintenance.

If you notice any of these signs, reach out to your expert Plano AC replacement team. We can help evaluate your unit, discuss your options to ensure you receive the best system for your cooling needs. Most modern systems have excellent energy efficiency and use much less energy than older models.

Keep Your Heater Working Properly All Year Round

If you want to stay cozy and avoid problems this winter, here are some tips for keeping your heating unit working properly.

Keep Outdoor Vents Clear

If your home’s furnace vents to the outside, it’s essential that you keep this clear of obstructions. This time of year, snow drift can accumulate near the vent and block the flow of exhaust. However, this isn’t so much a functionality issue as it is a safety hazard. When exhaust can’t leave, it will be dispersed throughout your house instead.

This can result in a dangerous buildup of carbon monoxide, a colorless, odorless gas that can prove fatal in high enough levels. While you’re clearing your sidewalks and brushing off your car, take a few minutes to clear the snow away from your exterior vents, too.

Change Your Filters

You should make sure to change your heater's filters as often as indicated by your unit’s manufacturer. These filters are responsible for cleaning the air from your furnace, and they can become clogged surprisingly fast. A full filter won’t allow as much warm air to pass through, which means you may experience inadequate heating. Furthermore, any allergens trapped in the fibers are released back into the air, worsening your allergies and making you feel miserable.

Schedule Professional Maintenance

At least twice per year, it’s recommended to have a Plano heating technician come to your home to inspect the unit and perform routine maintenance. The technician will use this time to clean all of the components, inspect them for potential issues and replace them if necessary. By adhering to a regular maintenance and inspection schedule, you can reduce the chances that you’ll have to deal with an inconvenient furnace outage on a cold winter’s night.

Duct Cleaning

If you want cleaner air and a more efficient heating system, then consider having your ducts cleaned at least every three years. Over time, ducts will collect large amounts of dust and debris. This reduces space and increases resistance, which cuts down on the flow of warm air throughout your home.

By keeping them clean, you’ll experience higher efficiency and better air movement. In addition, a duct cleaning will also decrease concentrations of airborne allergens in your home. It’s important to keep in mind that this is a job for properly equipped professionals and should never be attempted by yourself.

Be Keen to Problems

Part of good furnace maintenance means being able to recognize when things aren’t working properly. It’s important to familiarize yourself with these signs and to keep an eye out for them. Stay alert for knocking or grinding sounds, uneven heating, electrical issues or anything else out of the ordinary. If you notice one or more of these signs, call a professional Plano heater repair specialist right away so they can diagnose and fix the problem.
