AC Installation & Replacement

Air Conditioning Installation in Granbury, TX

Trane-Certified AC Installation for Granbury & Hood County Since 2015

David C. Bates Sr. founded Bates Heating & Air in 2015, and we’ve been installing and replacing air conditioning systems for Granbury homeowners and businesses ever since. Granbury summers run hot from May through October, with temperatures regularly exceeding 90 degrees for weeks at a stretch. A system that’s properly sized and correctly installed can handle that sustained demand. One that isn’t can cost you more to run and can fail sooner. We offer free estimates on every air conditioning installation and replacement project, residential or commercial.

Why Granbury Homeowners & Businesses Choose Bates Heating & Air

We’re a Trane-certified installation provider, which means we’ve met the training and technical standards Trane requires of contractors who install their equipment. That certification matters most on a job like this: an incorrectly installed system can underperform and wear out early, regardless of the brand on the label. Trane certification reflects installation quality, not just equipment volume.

Beyond Trane, we hold an A+ rating with the Better Business Bureau (maintained since 2016), operate in full compliance with the Texas Department of Licensing and Regulation (TDLR), and carry full insurance on every job. We also service all major brands including Bryant, Lennox, and Carrier, so we can work within your budget and equipment preference rather than steering you toward a single line.

Our customers throughout Hood County have left us hundreds of 5-star reviews, and we back that reputation with 24/7 emergency availability. If your system fails during peak summer heat, we’re reachable around the clock.

Repair or Replace? Knowing When It’s Time for a New System

Most air conditioning systems last between 10 and 15 years. As a system approaches or passes that range, repair calls become more frequent and efficiency drops. If your system runs continuously through a Granbury summer but still can’t hold a comfortable temperature, or if your energy bills are climbing without any change in usage, the unit is working harder than it should for diminishing results.

These are the clearest signals that replacement is worth evaluating:

Age of 10 or more years with a recent history of repairs
Rising repair costs that are approaching or exceeding half the cost of a new system
Inconsistent cooling during sustained 90-plus-degree stretches
Higher monthly energy bills without a change in usage patterns
Constant cycling without reaching the set temperature

A Bates Heating & Air technician can assess your current system and give you a straightforward comparison of repair versus replacement costs before any work is committed to.

What to Expect During an AC Installation

A proper installation starts before any equipment is touched. We perform a load calculation that accounts for your home or building’s square footage, insulation, window placement, and sun exposure. This step determines the right system size, and it’s where many installations go wrong. An undersized unit can’t keep pace with North Texas heat. An oversized unit short-cycles, shutting off before completing a full cooling cycle and leaving excess humidity indoors.

For properties near Lake Granbury, where elevated ambient humidity adds to the cooling load, and for older homes with less insulation, accurate sizing calculations carry even more weight. Once sizing is confirmed and equipment is selected, we complete the installation and test the system before we leave, verifying thermostat calibration, airflow balance, and refrigerant charge. Most manufacturers also require professional installation by a certified contractor to keep warranty coverage valid, which is another reason the installer you choose matters.

Choosing the Right AC System for Granbury’s Climate

Granbury’s long cooling season and the added humidity from Lake Granbury make system selection more nuanced than picking a brand and a tonnage. Two factors shape the decision: system type and efficiency rating.

System Types

Central split systems are the most common choice for Granbury homes that already have ductwork in place. They distribute conditioned air throughout the home using the existing duct network. Ductless mini-split systems are a practical alternative for room additions, detached structures, or older homes without ductwork. They also allow independent temperature control by zone, which suits commercial spaces and multi-use buildings.

Efficiency Ratings

New equipment is rated using SEER2 (Seasonal Energy Efficiency Ratio 2), the current federal efficiency standard. A higher SEER2 rating can mean lower operating costs over the life of the system. Granbury’s six-month cooling season means that efficiency investment has more months each year to pay back through reduced energy bills compared to milder climates. We carry equipment across multiple efficiency tiers from Trane, Bryant, Lennox, and Carrier, and financing is available to help manage the upfront cost.

What a New AC System Delivers

Modern high-efficiency systems use significantly less energy than units manufactured a decade or more ago. That difference can show up on your monthly electricity bill, particularly during Granbury’s long stretch of sustained summer heat. A properly sized new system can also distribute cooling more evenly, addressing the hot spots and persistent humidity that often develop as older or oversized units decline.

Beyond efficiency and comfort, new equipment is less likely to fail during peak summer demand than aging equipment with worn components. Worn compressors and aging air handlers carry the highest failure risk exactly when you need them most. Many newer systems also support smart thermostat integration and advanced air filtration, giving you better control over comfort and indoor air quality. Quieter operation is a common observation from customers who’ve replaced aging compressors with current-generation equipment.

"Our second time using Bates. Just recently had them install a complete HVAC system and a mini split. This company is great. The owner is David Bates, He is extremely knowledgeable on all aspects of HVAC. He gave me great options for the equipment, and his bid was excellent.

They said they were going to do with no surprises. If you’re looking for an HVAC company in Granbury, I would definitely refer Bates Heating & Air!"

I’ve used Bates multiple times now.
“Their service is always fast! Both Adam and the entire Bates team are friendly, quick, and knowledgeable. I highly recommend them!”

Eliza

I’ve used Bates multiple times now.
"I’ve used Bates multiple times now, and have been pleased on all occasions! Back in May, our A/C stopped working. They had someone over here within a few hours, found the issue quickly (capacitor), and replaced it.
This week, I noticed both of my thermostats were off as well as our entire HVAC system. I could not get it to come back on so I called Bates. Again, they had someone over here within a few hours. Adam quickly found the issue, fixed it, and was on his way. Both Adam and the entire Bates team are friendly, quick, and knowledgeable. I highly recommend them!"

I highly recommend Bates!
“They are trustworthy and honest and that means more to me than anything. Thank you Bates for the fantastic service! You have one more loyal customer.”

Chris

I highly recommend Bates!
"Our HVAC system failed on us during the summer and I had heard good things about Bates so we decided to give them a call. First they tried to service the system which got us back up and running for a few days but then we lost our cooling again. They came back out and discovered a leak. We decided to replace the system and they presented multiple options like a good, better, best scenario. They were up front and honest in all of their interactions. They genuinely care for their customers and really made sure we were taken care of. We had another company come out that told us there was nothing they could do. Bates came out and immediately had answers to what was going on. They even gave a discount because I am a Veteran. I highly recommend Bates if you need anything with your HVAC system. They are trustworthy and honest and that means more to me than any "good deal". Thank you Bates for the fantastic service! You have one more loyal customer."

Bates was the right call to make.
“Called Bates and they were out the same day to evaluate the situation. They came out and installed my new system the very next day.”

Tony

Bates was the right call to make.
"My furnace went out just two days before the cold snap. Called Bates and they were out the same day to evaluate the situation. They came out and installed my new system the very next day. Temps were being to fall as they left the property. My home was warm and safe before the ice hit the ground. Bates was the right call to make.
Thank you Bates for quick, reliable and affordable service!
Highly recommend your next a/c and heating call, be Bates Heating and Air."

They have the best techs!
“The owner, David, is always a phone call or text away. When it's time for an all new system, I know who I'll be calling. Highly recommend Bates Heating & Air.”

Kim

They have the best techs!
"Bates Heating & Air has kept my 2008 Carrier Infinity System running right without breaking my bank, which is no small feat, and many services I'd called in the past wouldn't even try because of this system's complexity and reputation for being persnickety. The owner, David, is always a phone call or text away and is vested in customer satisfaction. A recent service call by Adam, shows that Bates hires the best techs and people too. When it's time for an all new system, I know who I'll be calling. Highly recommend Bates Heating & Air."
