What’s the best thermostat setting for summer in Houston?

For optimal comfort and energy savings during summer in Houston, set your thermostat to 78°F (25°C) when you're home. If you're away, raising it to 85°F can help reduce cooling costs. Using a programmable or smart thermostat can make these adjustments automatic and more efficient.

Do you provide emergency after-hours HVAC service in Houston?

We are available 24/7 to take your call for emergencies. Our appointment hours are listed above.

How can I improve indoor air quality in Houston?

To improve indoor air quality in Houston, start by regularly changing your HVAC filters, scheduling routine maintenance, and using air purifiers. Consider duct cleaning if your home has excessive dust or allergy symptoms. Proper ventilation and keeping your home clean are key to healthier air.

How often should I service my HVAC system in Houston?

It’s ideal to service your cooling system each spring and your heating system each fall to ensure you find small issues before they become big problems.

Do you offer HVAC financing in Houston?

We work built relationships with several lenders to ensure our customers are able to restore comfort in their homes. Ask your technician about your financing options.

How often should I have my furnace serviced in Houston?

It’s recommended to have your furnace professionally serviced once a year, ideally in the fall before the heating season begins in Houston. Annual maintenance helps ensure safe operation, improves efficiency, and can extend the life of your system.

How often should I have my air ducts cleaned in Houston?

It’s generally recommended to have your air ducts cleaned every 3 to 5 years in Houston, or more often if you notice dust buildup, allergies, or musty odors. Homes with pets, recent renovations, or high pollen levels in Houston may benefit from more frequent cleanings to maintain healthy indoor air quality.

How often should I schedule AC maintenance in Houston?

You should schedule AC maintenance once a year, ideally in the spring before the cooling season starts in TX. Regular tune-ups help your system run efficiently, prevent breakdowns, and extend the life of your unit, especially important in Houston's summer climate.

What size HVAC system is right for my home in Houston?

The right HVAC system size for your home in Houston depends on factors like square footage, insulation, number of windows, and local climate. A professional load calculation ensures your system is properly sized for comfort and efficiency. Oversized or undersized units can lead to higher energy bills and uneven temperatures.

“Been a long time customer for a reason. I can always rely to get my issue fixed the first time by experienced professionals. Marcos took care of me and he was very knowledgeable and friendly throughout the entire repair in getting my AC cooling. He took time to explain the issue, was very thorough, and answered all my questions I had regarding my electrical issue which can be hard to diagnose. Will not hesitate to use their services in the future.”

The technician arrived on time, was professional, and took the time to explain what was going on with my system instead of rushing through the visit. Everything was clearly laid out before any work was done, and the service was completed efficiently. Definitely appreciate the honesty and customer service would recommend.”

“I had an excellent experience with Joseph Wilson during my AC maintenance service. He was professional, punctual, and extremely thorough with the detailed maintenance he completed. Joseph took the time to explain what he was doing, checked everything carefully, and made sure my system was running efficiently before he left. His attention to detail and knowledge really stood out, and I felt confident knowing my AC was in great hands. I highly recommend Joseph Wilson for anyone looking for reliable and high-quality HVAC service.”
