Rock-solid warranty coverage can be great for people who are all about peace of mind and ease.

We’re cooling and heating system experts who can provide you with maintenance work that’s efficient, thorough, comprehensive and, perhaps most importantly of all, trustworthy.

It is extremely important to control the humidity level in your home. If the humidity is too low, then it can lead to dry skin, lips and scratchy throats. It can also make your home uncomfortable. Mold and mildew can grow if the humidity level is too high. The ideal humidity level is between 40 and 60 percent. You can control the humidity level in your home by using a humidity control device. You can also use your air conditioner.

Is your a/c subpar?

Florida temperatures can be sweltering, and without air conditioning, the summer days and nights can become near unbearable. An air conditioning unit is an essential part of your home, as it ensures a comfortable environment indoors and allows you to escape the brutal outside heat. Beyond the comfort it provides, having an AC can protect furniture and electronics from moisture, prevent electronics and other devices from overheating, and improve air quality if the filters are kept clean and maintained.

Hot summers in Florida are not FUN

Your air conditioner is necessary for surviving the hot summers in Florida. However, it may be costing you more money than it has to. If your air conditioner is too large, then it will cost you extra money. Your air conditioner will also cause you to spend extra money if it is inefficient.

You can contact Jim McDonald if you are in need of air conditioning service. We can perform an A/C replacement if your air conditioner is too large. We can also perform an A/C repair if your air conditioner has problems. Additionally, we can tune-up your air conditioner.

A/C Maintenance is a MUST

It is important for you to get air conditioner maintenance at least once a year. Even if you have a brand new air conditioner, you will still need to get it maintained at least once a year. Regular air conditioning service will help keep your air conditioner working at its peak. This will reduce the need for AC repair. You will also be able to keep your air conditioner longer. A/C replacement is expensive, so you will save a lot of money by getting maintenance.

Furthermore, a well-maintained air conditioner will not use as much energy. This can help cut your electric bill.


Your thermostat is one of your most powerful tools in keeping your home temperate. In the summer, it keeps things cool and in the winter, it keep things warm. A properly working thermostat allows you to keep your home comfortable.

How Your Thermostat Helps You

Your thermostat helps you by keeping the air in your home a comfortable temperature whether you are home or not. It helps keep the temperature low enough on hot days for pets, furniture, and loved ones while keeping things cozy on days where the temperature is too cold. Best of all, with your thermostat working properly, you can program set temperatures that adjust according to the time and keep your home properly cooled or heated. There is no need to touch a single button when your thermostat is working for you.

When It’s Time To Repair Your Thermostat

The time to repair your thermostat is when it stops performing. When you find that you have to manually turn your air conditioner on or off, you will know that you have a broken thermostat. Other signs include broken wires and the fan shutting off before it reaches the desired temperature. When you need AC repair, A/C replacement, thermostat repair, thermostat replacement, or other airconditioning service repairs, Jim McDonald Heating & Cooling Inc. is here to help.

Thermostats are a crucial part of the modern American home. Being able to control the conditions within your house makes living more comfortable (and possible in otherwise inhospitable areas), but what does a thermostat really do? We know it makes the temperature go up and down, but how can a tiny box with a few switches control all of that?

For most people, their home will be controlled by a single thermostat mounted on the wall. This handy device can take preset temperatures and heat or cool the entire house to that temperature before shutting off. Thermostats constantly check the air temperature around them, activating again when the temperature falls outside of that preset range. Depending on your specific setup, this may involve activating heaters or air conditioners or regulating heat transfer fluid movement through a radiator.
