After-Hours Air Conditioning Repair Service

When you experience an electrical issue with your air conditioner, it can require emergency AC repairs. These can pose dangerous threats to your household, including electrical fires, and leave you without a working air conditioner. This is especially problematic if it’s hot out.

You need to call for emergency air conditioning services at your house. While waiting for the expert to arrive, there are some steps you can take on your own, including checking the circuit breaker to see if it tripped and if that’s what’s causing the problem.

When an AC contractor arrives, they will inspect the wiring and other electrical components to diagnose and repair the issue. DiBiase Heating and Cooling Company is available 24/7 for your convenience and peace of mind

What To Know About New Air Conditioners

When you schedule central air conditioning installations, your focus might be on the work being done to get the new unit up and running. However, it’s just as important to know what to expect with a newer, more modern model.

For one, newer units are larger than older systems. These can be 20-50% bigger in height, length, and width than older models. To fit the new system, technicians may need to relocate your new system or enlarge the spot.

Doing this might require you to move your ductwork or adjust it. It might also increase the timeline and budget of the installation. However, this is usually something you are made aware of before the day of the installation.

If you have questions or concerns about your AC installation, call DiBiase Heating and Cooling Company!

When to Call Experts for Ductless Mini Split AC System Repairs

When your ductless mini split AC system malfunctions, you might wonder if you need to schedule professional repairs or if you can handle the work on your own.

Depending on the issue, you can fix the problem yourself. Before calling an expert, you can check the air filter to see if it needs to be replaced, ensure the thermostat is set to “Cool,” and make sure a circuit breaker didn’t trip.

If these troubleshooting tips do not resolve the issue, you should schedule professional cooling repairs in Coatesville, PA.

Why a Broken Thermostat Is a Heating Emergency

With a fully functioning thermostat, your central heating system can work properly. If your thermostat malfunctions, you might consider this a minor problem. However, it requires emergency heating repairs.

While waiting for a heating contractor to arrive, there are steps you can take to troubleshoot the issue. These can include first checking if the thermostat is correctly set to Heating. If it’s set to Cool, then you can switch it. This should correct the problem.

Next, you should check the device’s batteries. Make sure these are working. If not, then replace them. You should also ensure nothing is blocking the thermostat, preventing it from adequately reading the temperature in the room.

Signs Your Heating System Is Failing

It’s essential to schedule heater replacements at the first signs that your system is malfunctioning. It’s also important to recognize which symptoms imply repairs versus which ones can indicate you need to install a new system.

One of the most obvious signs is if your house is no longer heating to the desired temperature. While this could be an issue with your thermostat, it’s crucial to have a technician inspect your unit, as it can also indicate your system is failing.

Other symptoms to watch for include if your unit is making odd noises or if your utility bills are suddenly increasing. This can indicate your system is losing efficiency.

If you notice any of these problems, call our experts at DiBiase Heating and Cooling Company for heater repair services, inspections, and replacements. We provide the ultimate customer experience in Coatesville, PA, and beyond.

Importance of Scheduling Heat Pump Maintenance

It’s crucial to schedule annual maintenance services on your heat pump to keep it working correctly. These routine tune ups allow heating contractors to conduct a complete system inspection and look for defects that must be repaired.

Performing these services also helps improve the unit’s performance, making it more energy-efficient and prolonging the life expectancy of the system.

Home Energy Audits

A home energy audit is a detailed inspection that identifies areas where energy might be wasted in your home, such as through drafts, insulation gaps, or inefficient appliances. By targeting these problem areas, we can make recommendations to boost efficiency, reduce utility costs, and increase overall comfort.

Signs that your home might benefit from an energy audit include uneven temperatures, high energy bills, or noticeable drafts. Once the audit is complete, our team offers customized solutions—like air sealing and insulation improvements—to enhance your home’s energy performance.

Water Heater Repair and Replacement

Water heater repairs are typically needed when you notice leaks, unusual noises, or insufficient hot water; these issues can often be resolved to restore functionality. Replacement becomes a more cost-effective choice if your unit is over 10-15 years old, breaks down frequently, or no longer meets your household’s hot water needs.

We service both tank-style and tankless water heaters, offering expert repairs and replacements for each type. Upgrading to a new, energy-efficient water heater not only ensures reliable hot water but can also reduce your energy costs and provide improved performance.

Water Treatment Solutions

A whole-home water filtration system provides clean, filtered water from every tap by removing contaminants such as chlorine, sediment, and other impurities. Adding a water softener can further benefit your home by reducing water hardness, which helps prevent mineral buildup in plumbing and appliances while also improving water quality.

Common signs that water treatment may be needed include hard water spots, mineral deposits, or an unpleasant taste or odor. We offer comprehensive water treatment solutions, including whole-home filtration and softening systems, customized to fit your home’s specific needs.

I arrived to the customers home to service their 3 yr old gas furnace system. 
I started with checking the air filter and replaced , the filter size is 16x25x1. I checked all my electrical connections and voltages. I inspected and tested the  burners , flame sensor and the igniter. I water tested all tubing and hoses. I inspected the exhaust and fresh air pipe for restrictions and bellies. I inspected the inducer and the blower motor operation. I checked and tested for combustion and took temp rise splits at the return and the supply. Everything is running fine at this time of service. 

Left 2 estimates for the customer for adding a wet switch water safety to the system and recommended in adding a apco x ultra for clean air purification. She will review the recommendations.

Boiler domestic hot water works. Couldn’t get the boiler to run for both zones. I traced all my wires . Found transformer that powers the relay box wasn’t stepping down to 24 volts, which will run the thermostats. I added a new transformer 40va . I turned the system back on and now both zones are actually calling for heat at the relay board and everything is heating up again. Warranty new system . Please follow up in a few days and check on the customer.

Suction pressure drops to 40 psi quickly and unit cuts off on low pressure.
Found refrigerant leak at liquid line brazed joint at evaporator.
Uploaded photos and video of leak.
We will return next week to fix leak. 

Also verified DC volts, wiring connections and transducer pressures DC volts. Because original error codes are 184.05 which is hard lockout. 

They are only available Monday morning. Talked to Joe. We will schedule to return Monday morning and complete repair.

For now system will only work on emergency heat. Do not try to change to heat or cool

I had a new HVAC installed today by this company. The guys arrived at 8:00 a.m. I met Riley first, and the other two fellows shortly after. They were very professional, started working immediately. After installation, Riley explained how everything worked and if I had any questions, to call the office. Overall experience was excellent.

On the day we moved in to our house, we discovered that our AC unit needed to be replaced in the middle of a heat wave. The whole team at DiBiase has been very responsive to our needs and helpful. They were easy to work with and provided top quality equipment and service. I couldn't have asked for a better experience!

Barry came out to help diagnose an AC issue. Was fast to identifying the issue with a semi clogged drain and was up and running with no issues. Also good to deal with someone with a good attitude during the summer for a last minute issue.

Three trips to fix my clogged condensate drain line. The first technician didn’t clear the clogged line but he did clear the alarm circuit. The second technician DID clear the clogged condensate drain line, BUT, when he reinstalled the cover he crushed the infrared motion sensor eye (“Intelligent Eye”). The second technician DID NOT clear the alarm. The third technician reinstalled the cover correctly and cleared the alarm. The third technician took note that the “Intelligent Eye” lense was damaged. I am still waiting for Dibiase to contact me about this issue.

Riley and team installed a mini split today. Top of the food chain work from DiBiase, as usual. Have used DiBiase Heating and Cooling a few times now. For my latest appointment, I got some recommendations and a quote for some HVAC work for my recently gutted basement. Joe was transparent and gave some great insight and options. Highly recommend their service.
