Keep Cool All Summer Long with Air Conditioning Services

The hottest day of the year is when your AC unit works the hardest to cool your home. Welsch offers repairs, maintenance, and installation services to keep your system working reliably throughout the hot summer months.

Welsch Has the Tools to Improve Your Indoor Air Quality

Improving your home’s indoor air quality will make your air healthier and your home much more comfortable. In the winter, you might notice your family members sneezing and coughing more. You might also be annoyed by static electricity shocking you with every surface you touch. These issues are caused by dry air. A humidifier can add moisture to the air in your entire home which can alleviate these issues. A whole house humidifier needs very little maintenance and is plumbed directly to your water line so you don’t have to worry about refilling a tank.

Every HVAC system has an air filter that removes particulate matter from the air. This only does so much to help with your indoor air quality. By upgrading your HVAC system with an air cleaner, you’ll have a more powerful filter to keep the air your breathe clean and free of bacteria, allergens, and pathogens that make your family sick. Air cleaners can pick up finer particles than your standard filters, which makes them worth the investment.

If your home seems stuffy, has trouble retaining a set temperature, or doesn’t feel like the setting on the thermostat, your thermostat could be experiencing issues. We can help with repair or replacement thermostat services to keep your home consistently comfortable.

Our a/c fan went on the hottest day of the year. We have used Welsh for years and they were quick to respond and had a new system in the next day. Couldn’t be happier.


Rick did an outstanding job of assessing my needs, making appropriate suggestions, and fielding follow-up questions in a timely manner.

We called Welsch to provide a second opinion after another service provider recommended a new furnace. The technician was not only professional, prompt and courteous, he was unbelievably thorough!

This is just a short note to let you know how courteous and educational our recent technician was serving us for our regular fall service.  I was searching for someone to explain these issues to me and he knew his subject matter and was more than gracious with his time...
