Your Guide to Air Conditioning, Heating, Plumbing & Electrical Services

Air Conditioning

We provide a full range of cooling solutions tailored to your space, including central air conditioning, energy-efficient ductless mini-splits, and heat pumps. Whether you need a system for a single room or a large commercial building, we can help you choose the right model for your needs.

For optimal performance and energy efficiency, we recommend a professional maintenance check at least once a year—ideally in the spring before the peak cooling season. Regular servicing helps prevent costly breakdowns and extends the lifespan of your unit.

First, check if your thermostat is set correctly and ensure your air filters aren’t clogged with dust. If those aren’t the issue, you may have a refrigerant leak or a failing compressor. We recommend turning the unit off and scheduling a repair immediately to avoid further damage.

You can lower your energy bills by installing a programmable thermostat, sealing air leaks around windows and doors, and keeping your filters clean. Additionally, upgrading to a modern, high-SEER (Seasonal Energy Efficiency Ratio) unit can significantly reduce energy consumption compared to older models.

Yes! We understand that a broken AC in the middle of a heatwave is more than just an inconvenience. We offer emergency repair services to ensure your home or business stays cool and comfortable when you need it most.

Heating

The air handler is the indoor component of your HVAC system that “handles” the air. It contains the blower motor, evaporator coil, and filter. Its job is to pull air from your home, condition it (heat or cool it), and then blow it back through your ductwork. When it fails, your entire system loses the ability to move air, regardless of how well your outdoor unit is working.

Key warning signs include weak airflow from your vents, persistent motor noises (grinding or squealing), and frequent electrical issues like tripped breakers. If your unit is over 10–15 years old or requires an expensive motor or coil repair, a replacement is often the more cost-effective choice for long-term reliability.

It is possible, but we generally advise against it. HVAC systems are designed as matched pairs. Installing a modern, high-efficiency air handler with an older outdoor condenser can lead to poor performance, increased humidity levels, and may void your manufacturer’s warranty. For the best results, we recommend replacing both to ensure they are perfectly compatible.

A standard air handler replacement typically takes 4 to 8 hours. Our team works efficiently to remove the old unit, secure the new one, and verify all electrical and ductwork connections. We strive to have your home’s airflow restored and your family comfortable by the end of the day.

Newer models often feature variable-speed motors, which are significantly quieter and more energy-efficient than older single-speed versions. They provide better humidity control—essential for DFW summers—and more consistent temperatures throughout your home, helping to eliminate hot or cold spots.

Plumbing

Warning signs include slow drains, gurgling noises from your toilets, unexplained spikes in your water bill, or low water pressure. If you notice damp spots on your walls or a musty odor, you may have a hidden leak that requires professional detection.

Yes. Dwello Home Service provides 24/7 emergency plumbing repair for urgent issues like burst pipes, major sewer backups, or gas leaks. We are ready to respond at any hour to protect your home from water damage.

Most common repairs, such as clearing a clog or fixing a leaky valve, are completed the same day. Our technicians arrive in fully stocked trucks with the tools and parts needed to resolve the majority of plumbing problems in a single visit.

A sudden increase is often caused by a running toilet or a hidden leak. In the DFW area, shifting clay soil can also cause slab leaks (leaks under your foundation). We use specialized acoustic equipment to find these leaks without unnecessary digging.

When a North Texas “Arctic blast” is forecast, you should insulate exposed exterior pipes, let your faucets drip slowly, and keep cabinet doors open to allow warm air to reach the plumbing under your sinks.

Electrical

Immediate red flags include burning smells (often like fish or burnt plastic), outlets that are warm to the touch, buzzing sounds from your panel, or flickering lights when you use large appliances. If you notice any of these, shut off the breaker to that area and call us immediately—these are classic signs of potential electrical arcing or overheating.

Yes. Dwello Home Service provides 24/7 emergency electrical repair. Hazards don’t wait for business hours. Whether it’s a sparking panel, a total power loss, or a partial outage where half your home is dark, our team is on standby to stabilize your property.

In 2026, many DFW homes are upgrading to 200-amp panels to support modern demands like EV chargers and high-efficiency heat pumps. If your panel is over 25 years old, uses outdated brands like Federal Pacific or Zinsco, or if you’re still relying on a 100-amp service, an upgrade is essential for both safety and home insurance compliance.

For most Dallas-Fort Worth homes, a Level 2 EV charger installation typically ranges from $800 to $2,500. The final investment depends on the distance between your panel and the garage, whether you need a new 240V circuit, and if your panel has the available capacity (amperage) to handle the load.

A tripping breaker is a safety feature preventing a fire. It usually means you are overloading a circuit (too many devices on one line). However, frequent “nuisance” trips without a clear cause can indicate a faulty breaker or a dangerous “short circuit.” We recommend a professional diagnostic if your breakers trip more than once or twice a month.
