AC Repair 

Procrastinating AC repairs could prove to be a costly mistake. A malfunctioning AC is more than just an inconvenience, it can draw more energy than usual, causing your energy bill to spike. A malfunctioning AC can put your health and safety at risk.

If your AC’s evaporator coils are dirty, the system will circulate unclean air. Exposure to particulate pollution can aggravate lung disease and increase one’s risk of respiratory infections. A malfunctioning AC can start a house fire or cause carbon monoxide poisoning.

AC repairs are best left to experts. If you take the DIY route, you may make a mistake and things could take a turn for the worse.

McDonald Home Solutions is your go-to team for air conditioning repair. Whether your AC is not cooling properly or not cooling at all, we can help. Our technicians will get to the root cause of your issue and treat it before it snowballs into a major problem.

There is no one-size-fits-all approach to AC repair. Two systems exhibiting identical symptoms may have different issues. No one knows this better than us. We avoid jumping to conclusions and take the time to inspect your system and perform tests to diagnose your issue accurately. Once we make an accurate diagnosis, we will help you plan a course of action.

Your safety is our number one priority. Our team takes multiple precautions to make sure that your family and our technicians both stay safe.

New System Installation

Thinking of installing a new AC system? It’s important to remember that how you install your AC will affect its efficiency.

Improper installation of an air conditioning unit can result in leaky ducts and other problems or cut short the system’s service life. Problems that arise due to faulty installation will not be covered by the manufacturer’s warranty.

Stick with the experts at McDonald Home Solutions to avoid the pitfalls of DIY installation. An oversized unit will short cycle. An undersized unit, on the other hand, will work harder and longer to cool your spaces, causing your energy bill to shoot up.

We offer top-notch AC installation services. We will help you choose the right-sized AC for your home.

Our team will perform the necessary calculations to accurately determine your home’s heating and cooling needs. A Manual J Load calculation takes many factors into account such as square footage, number and position of windows, and type and quality of building materials.

We plan AC installation projects down to the last detail. We take all necessary precautions to steer clear of installation errors to make sure that your home stays cool and free of any installation issues.

AC Maintenance 

Like all other household equipment, ACs need regular care and maintenance. A poorly maintained AC is a recipe for an expensive breakdown.

Stay on top of maintenance. To prevent problems, schedule a tune-up at least once every year to have your unit inspected for problems and potential issues.

At McDonald Home Solutions, we pride ourselves on being thorough, knowledgeable experts. During a tune-up, we will:

  • Clean the condenser and evaporator coils
  • Check and test the refrigerant and top off, if necessary
  • Clean and repair fins
  • Inspect airflow
  • Inspect electrical controls and tighten loose connections
  • Lubricate moving parts
  • Check the motor fan and blades to ensure they are not damaged
  • Check and clean condensate drain line
  • Check, clean, and replace filters
  • Inspect blower components

There are numerous benefits to regular AC unit maintenance. Periodic maintenance improves AC efficiency, extends system lifespan, and minimizes common AC problems. These common issues include hot and cold spots, inadequate airflow, and poor indoor air quality.
