Heating, Cooling & Water Heater Repairs You Can Count On
John James Appliance Service knows that when you live in Houston, the weather isn’t something you can ignore. Summers can get hot and humid, while winters bring their own share of chilly nights. That’s why keeping your heating, cooling, and water heating systems in good shape is essential. We’re not just appliance experts—we’re your go-to technicians for HVAC repairs as well.
We work year-round to make sure your home stays comfortable in every season, with straightforward pricing, fast response, and same-day service when possible.
Honest Service and Straightforward Pricing
We charge a diagnostic fee of $98.50 + tax. If you decide to go forward with the repair, that fee is credited toward the total repair cost. That way, you’re not paying twice. Whenever possible, we prepare for the repair before arriving so we can complete the job in one visit.
We Service All Refrigerator Types
Our experienced technicians work with every style and brand of refrigerator on the market. Whether you own a basic top-freezer unit or a high-end built-in model, we can help. We repair:
- Side-by-Side Refrigerators
- French Door Refrigerators
- Top- and Bottom-Freezer Units
- Built-In and Counter-Depth Models
- Compact and Small Commercial Refrigerators

Your Local HVAC Repair Team
Because we’re based right here in Houston, we understand how important dependable HVAC systems are to everyday life. Whether your AC goes out in the middle of a heat wave, your heater won’t fire up on a cold morning, or your water heater starts acting up, our team is ready to help.
We repair most major HVAC brands and handle everything from
simple fixes to full component replacements. And since we work with
local suppliers, we can often get the parts needed the same day.
Air Conditioning Repairs—Beating the Houston Heat
Houston summers can be brutal, and a broken air conditioner can turn your home into an oven. That’s why AC repair is one of our busiest services during the summer months.
We service central air units, ductless mini-splits, and window units. Common AC issues we repair include:
- Warm Air Blowing or No Cooling at All
- AC Unit Won’t Turn On
- Frozen Coils or Refrigerant Problems
- Weak Airflow or Uneven Cooling
- Thermostat Malfunctions
- Unusual Noises or Leaks
Whether your AC needs a quick fix or a major repair, our technicians work efficiently to get your cooling system running again. If we can get the part the same day (and we usually can), we’ll complete the repair on our first visit.
Call or text (281) 933-6900 to schedule your AC repair today.
Heating Repairs—Staying Warm in the Cooler Months
Even though Houston isn’t known for harsh winters, cold snaps do happen—and they can catch you off guard. When your heating system goes out, you don’t want to wait days for service.
We repair furnaces, heat pumps, and other heating systems, including common issues like:
- System Not Turning On
- Weak or No Airflow
- Uneven Heating
- Thermostat or Sensor Failures
- Blower or Ignition Problems
- Strange Smells or Noises
Our heating services peak during late fall and winter, but we’re available year-round for preventive maintenance and repair to make sure your system is ready before temperatures drop.
Schedule your heating repair today and keep your home warm when it matters most.
Water Heater Repairs—Year-Round Service
Unlike heating and cooling, hot water is something your home needs every single day, no matter the season. That’s why water heater repair is one of our most consistent services all year long.
We service both tank and tankless water heaters. Common problems we handle include:
- No Hot Water or Inconsistent Temperature
- Leaking Tanks or Valves
- Rusty or Discolored Water
- Pilot Light or Ignition Issues
- Unusual Noises or Pressure Problems
Whether your water heater is electric or gas, residential or small commercial, we’ll find the cause and get it back in working order quickly.
Same-Day HVAC Repair Service
When your HVAC system fails, time matters. Because we’re local and work with trusted part suppliers, we can complete most repairs on the same day. When you call or text us, we’ll ask for details about your system so we can come prepared to fix it on the first visit whenever possible.
Clear Diagnostic Pricing and Warranty
We believe in making things easy to understand.
- Diagnostic Fee: $98.50 + tax
- If you approve the repair, this amount is applied toward the total.
