Old Union Financial is an Indirect Consumer Finance Company offering unsecured loans within the Home Improvement Services Industry. All financing must go through your trusted Contractor.

"I thought I was getting and air condition and heater for 8,500.00 I purchase this in 2016 and will be paying this until 2027. They give you options on how to pay, but they will force charge your account double with fees and multiple other fees , if late. Even if you arent late and have talk with them, they will charge several fees that you cant understand. The statement is very hard to understand. The interest rate is 17.99 on the remaining balance principle.. So you always pay more in interest than monthly payment. Their bookkeepers couldn't even explain the fees.Iv even had one of their reps to come and fix something on it. Took hours to repair. Its a debt that I regret but I am a 70 year old woman living in hot Houston."

Heating and Air Conditioning questions, answered by experts

If your AC refrigerant is low, you may notice that the unit takes longer than usual to cool your home or that your energy bills are higher. You may even feel a warm breeze coming from the vents when the AC refrigerant is low. Don’t attempt to check refrigerant levels yourself. Only certified AC repair pros should check and refill refrigerant.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.
