Thermostats are more important than most people think. They give you complete control over your home’s heating and cooling system, allowing you to enjoy your favorite climate regardless of the outside weather. However, if your thermostat breaks down, you can’t control your residence’s internal temperature, significantly reducing your overall comfort.

Fortunately, Top Flight Heating & Air provides first-class thermostat repair and installation services to Milton, DE, residents in need.

Types of Thermostats

While it may seem there are many types of thermostats to choose from, they fall into one of three categories:

  • Mechanical thermostats
  • Programmable thermostats
  • Smart thermostats

Mechanical Thermostats

People looking for an economical thermostat that will keep their homes nice and comfortable year-round might want to consider a mechanical thermostat. Mechanical thermostats come standard in many older homes and provide limited control to homeowners. Although mechanical thermostats don’t have advanced regulatory temperature settings like more modern models, they are affordable and easy to use.

Programmable Thermostats

Programmable thermostats allow homeowners to set automatic temperature changes throughout the day to help them save money over time. You can program up to four different temperature adjustments, depending on the model you purchase. Most programmable thermostats fall into one of the following categories.

  • 1-week programmable thermostats
  • 5-2 programmable thermostats
  • 5-1-1 programmable thermostats
  • 7-day programmable thermostats

Each model offers unique temperature control options, so research the pros and cons before committing to a specific design for your needs.

Smart Thermostats

Smart thermostats are the most advanced thermostat model currently available. They utilize geofencing technology to learn your preferred room temperatures and adjust according to your schedule. Some even have a mobile app that allows you to program your thermostat while away from home.

Homeowners looking for superior comfort and comprehensive control over their cooling system will want to invest in a smart thermostat. Although most smart thermostats cost more than less advanced models, they can help you save money over time. They keep your home comfortable while you are home and decrease once you leave for work or run weekly errands.

Signs You Need Thermostat Repair or Replacement Services

Most thermostats display warning signs when they need professional repair or replacement services. However, many homeowners don’t know what to look for when they suspect their thermostat is on its last legs. Below are some telltale signs of a failing or faulty thermostat.

  • The thermostat won’t display your home’s internal temperature
  • Your air conditioner doesn’t maintain the set temperature
  • The heating and cooling system won’t turn off
  • Fluctuating room temperatures
  • A sudden increase in electricity bills
  • Unresponsive thermostat

Just bought a house and wanted the Heat Pump serviced before the winter months came in. Called Top Flight and was greeted with a friendly voice and was able to schedule promptly and when my technician arrived he was very gracious and polite. The unit was older about 18 years so I expected some issues, was pleasantly surprised that not bad at all. Gave me options and actually cheaper than I expected. Will definitely call them again when I need service!

Tyler came today to do the preseason check-up. He was right on time - literally to the minute. Polite, attentive. (I have a very new and nervous foster dog and he was very sensitive to her special issues). He checked out the heating equipment for my house; changed the filter; and I have every confidence I am ready for winter.

Tyler and Joseph came by today to do some follow-up work. They were on schedule and on time. They did a great job and I very much appreciate the work they did. Now my house is ready for encapsulation. Once the encapsulation is complete, and with my new AC/Heat system, both will add some great value and comfort to my home. Thanks TFH&A!

It was refreshing to find a local business that is both professional and customer service focused. Staff are very personable and get the job done quickly. No hard up-sell tricks during the service call... something that seems to be the norm with many other companies who force their service personel to try to generate extra income. We were impressed enough to switch all of our HVAC service contracts to Top Flight.
