Legacy Home Services, your local HVAC and Electrical contractor, exists to return respect to the home services industry in New Braunfels. Integrity. Honor. Service. Reliability. This Home Services company will distinguish itself from others by the virtues with which we conduct every business transaction. Legacy Heating & Air Conditioning Services, LLC started in February 2013 in Founder Chad Briggs’ garage. With a passion for serving people, Chad aimed to build an organization of individuals who genuinely care for the people in the community. A servant’s attitude was paramount, prioritizing respect for the customer and building a relationship rather than treating them like a transaction. Legacy quickly outgrew the garage through its stewardship towards customers and the community. In 2018, Legacy partnered with Trane Technologies to provide the New Braunfels community with the most reputable residential equipment. In October 2022, Legacy expanded by introducing the Electrical department and rebranding as Legacy Home Services, all while maintaining its focus on serving others. Legacy devotes its energy to become the #1 choice for home services in New Braunfels through its 5-star online reputation, loyal Legacy Family Plan Membership customers, highly trained and caring Comfort Technicians, and caring team of internal support team members. Above all, we care foremost about treating our customers like we would want to be treated, and work to return respect to the HVAC & Electrical industries in New Braunfels.

"Chris & Sam were an amazing team. They were right on time and got the work done very quickly and efficiently. They went the extra mile to answer our many questions and trained us on using our thermostats. They answered our inquiries re options on future expansion of our system. They made sure we knew how to properly use our system to optimize its capabilities. We are seniors, and not techies at all. They explained our 3-zone system to us in terms we could understand and even installed an app on our phones to remotely control our thermostats. Chris was so patient with us. What a great experience."

"We had a wonderful experience, as usual with Jon Wayne’s service. Several days ago a technician, Chris, came out and diagnosed a problem and had to order a part and just returned and replaced the inoperable part. Chris made an adjustment initially so we could still us our water heater until the new part was installed. We have been using Jon Wayne for 10 years and never been displeased with their service."

Window a/c unit installations FAQs

Running a window air conditioner to cool a small room often costs less than $4 per day, making it cheaper than central air for single-room cooling. However, central air might be more efficient if you're using multiple window units or need to cool a space larger than 1,000 square feet. Choosing the right size AC is crucial—a unit that's too big or small can waste energy and increase costs.

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
