Air Conditioner Replacement & Installation — Serving Denison, Sherman, Pottsboro, Bells & All of Grayson County!

We believe in keeping your existing system running for as long as possible — and we'll always explore every repair option before suggesting a new unit. If we do repair an aging system, we'll give you our honest assessment of how much life it likely has left, so you can plan ahead on your terms, not ours.
We don't push replacements. We don't upsell. What we do is give you the full picture and let you make the decision that's right for your home
and your budget.

When the time does come for a new system — whether your unit has finally reached the end of its life or the cost of repair simply no longer makes sense — Bee Cool AC is ready to make that process as smooth and straightforward as possible. Our team has set Rheem units for many years, and we’re proud to bring them to your home or business in Denison, Sherman, Pottsboro, Bells, and all of Grayson County.
Our lead contractor brings over 20 years of HVAC experience to every installation, and every technician on our team has between 5 and 13 years in the field. When we install a new system in your home or business, it's done right — properly sized, correctly installed, and built to last through years of Texas heat.
Our lead contractor has been installing Rheem systems for over 20 years and has built a trusted relationship with Rheem directly. When you choose a Rheem system, you're getting a team that knows it inside and out — from proper sizing and installation to long-term performance in North Texas heat.
Prefer a different brand? No problem. Bee Cool AC installs all major HVAC brands including: Goodman, Lennox, American Standard, Bryant, and more. At the end of the day, the best system is the one that fits your home, your budget, and your comfort — and we'll help you find it.

When you call Bee Cool AC, repair is always our first priority. We'll do
everything we can to keep your existing system running — and if we repair an older unit, we'll give you our best honest estimate of how much life it has left so you can start planning ahead without any pressure.
That said, there are situations where replacement genuinely becomes the smarter financial decision. Here's what our experienced technicians look for:
Signs replacement may make more sense than repair:
- Your unit is 12–15 years old or older and has needed multiple repairs recently
- The repair cost exceeds 50% of the cost of a comparable new system
- Your system uses R-22 refrigerant (no longer manufactured — increasingly costly to service)
- Your energy bills are rising significantly without a change in usage
- Your home has persistent hot spots or uneven cooling despite repairs
- Your system runs constantly but can't keep up with Grayson County summer heat
Even then, we'll lay out both options —
repair cost vs. replacement cost
— and let you decide. No pressure, no upselling. Just honest advice from a team that wants to earn your trust for the long haul.
We know a new AC system is a significant investment. Here's exactly how the process works with Bee Cool AC:
1. You call, we answer.
Call (903) 647-8283 and we'll get you scheduled for a free estimate.
Our technicians give a 15-30 minute heads-up call before arriving — no vague arrival windows.
2. We assess your home or building. Our team evaluates your existing system, ductwork, home size, and insulation to determine the right system size for your space. An improperly sized AC is one of the most common — and costly — mistakes in the industry. We don't guess.
3. We give you a free, upfront estimate. You'll receive a clear and honest estimate before any work is scheduled. No hidden fees. No surprises. Free estimates on all replacements and new installations in Sherman/Denison.
4. We install within 7 business days.
Once you approve the estimate, we get you on the schedule. Most installations are completed within 7 business days — so you're not waiting weeks in the Texas heat.
5. We install it right the first time.
Our experienced technicians handle everything — removal of your old system, installation of the new one, electrical connections, refrigerant charging, and full system testing before we leave.
6. We stand behind our work.
If something isn't right after we leave, we make it right. No runaround, no excuses — just a team that takes pride in every installation we complete in Grayson County.
Free estimates on all AC replacements and new installations — no diagnostic fee, no trip charge for estimates in Denison and Sherman.
For customers located approximately 10 or more miles outside of Denison and Sherman, a travel fee of $2.25
per mile round-trip may apply to service calls and installations.

travel fee. Not sure if your location applies? Call us at (903) 647-8283
and we'll let you know upfront.
Financing: We no longer offer in-house financing, but we want to be honest with you:
we've found that customers are almost always better served going through their own personal bank or credit union. Banks tend to approve their own customers more readily and at better rates than third-party HVAC financing companies. If you're facing a larger replacement cost, that's our genuine recommendation — and we're happy to talk through your options.
Don't just take our word for it — here's what real customers have said about working with our team.
"I had Bee Cool AC inspect my unit before I bought my house. He gave me a report of all the issues I could run into with it later on in a way I could understand and gave a quote on its replacement. I appreciated that I didn't have to call time and again to get answers or hear back. When they said they would call, they did — and I value that in a company. Jason is professional and efficient in his work and has a great staff (his sons and wife). I would definitely recommend them to anyone any day!"
"I would absolutely use Bee Cool again. My AC was not cooling so I called to get it looked at. They were quick to show up, got my AC back up and cooling, and were affordable."
Bee Cool AC, LLC is the Grayson County home of the same family-owned team that built a trusted reputation serving Texas families since 2016. Here's what those customers had to say:
"From start to finish — very professional, very knowledgeable, polite, and responded to my wife's questions without ignoring them, which is a huge plus for us since I'm usually not there. I will definitely be using them for all my service needs. Highly recommended. If I could give more stars I definitely would."
"So happy I chose them to come look at my AC — very professional but very nice! Very reasonably priced and they came and got right to it and finished quick. Other AC guys like to go very slow so they can charge more, but they were great!"
"Very professional. The tech knew exactly what he was doing and was able to explain to me what had happened in a way I could understand."
