Air Conditioning Services Deer Park

Deer Park summers aren’t without their sweltering days, so prepare for the season with a new air conditioner. Every family needs a comfy way to shelter from the sun, and few contractors can compare with National. We’ve been serving Deer Park for almost a century, so with us, you can count on lasting results. We handle commercial and residential installations, services, and repairs. Your air conditioner needs some work if:

  • It’s blowing warm air.
  • It’s not experiencing enough airflow.
  • It’s cycling frequently.
  • It’s creating too much humidity.

Our comprehensive air conditioning services include:

Heat Pumps

Heat pumps are a great option for Deer Park homeowners due to their versatility and efficiency. Functioning as both a heating and cooling option, heat pumps will keep your home at the right temperature all year long. Heat pumps let you only deal with one system, and their maintenance requirements are just as attractive. At National, we make sure you choose the perfect product for your needs and environment. But our services don’t end at installation, so we also perform tune-ups and repairs. Your heat pump probably needs attention if:

  • Your power bills have increased without explanation.
  • Your heat pump needs to work harder to achieve its effect.
  • Your heat pump requires frequent repairs.
  • Your heat pump is making unusual sounds.

Many problems can be repaired with a simple service, but we’re pros at diagnosing issues that require repair. No system lasts forever, though, so let us help you to navigate the market. We’ll guide you through your options so that you find the ideal product for your family.

If you’re ready to experience heating the National way, contact us online to schedule an appointment.

Commercial Heating & Cooling

Commercial HVAC specialists must deal with a growing number of difficulties. Legislation is constantly changing, so that old furnace you installed five years ago might not keep you above the law. As Deer Park HVAC pros, we know these regulations thoroughly. We make sure your installation is convenient, effective, and economical.

Commercial properties are changing as quickly as the law is. Businesses are becoming smaller, which reflects in their heating and cooling strategy. Today’s commercial appliances need to be compact enough to fit into tight places and light enough to move, so many of the products we install are even mounted on casters. It’s time to welcome a new era of flexibility.

Why Choose Us?

National has served the Deer Park community for 90 years, so we have a level of finesse that few can match. Our team has the skill to work with a huge range of systems, from ductless products to central AC units. Keep an eye on our special offers. We’re always coming up with new ways to save our clients’ money.

We’re here to help with your heating and cooling needs. Call us today at (513) 621-4620 to schedule service!

What Our Clients Are Saying

Brandon of National Heating did an excellent job servicing my AC. He is very thorough, knowledgeable, and professional. He discovered that the low outside temperature sensor had not been set up on my Evolution Connex Control and took care of it. I appreciated his top-notch service!

Thomas S.

Great company that I trust. Very thorough. I just had my air conditioner annual service. I used Help in the past. They always tried to upsell every opportunity they had. National Heating and A/C is the real deal from booking the appointment to the actual work. Every person I have dealt with is kind, knowledgeable, and…

Paul M.

I can highly recommend National (previously Nelson Comfort) Heating and Air especially if Sanjay is the company representative. He was beyond good in that he completely cleaned the outside unit and was very thorough with the ac equipment inside the house. He even destroyed a wasp nest that I had not noticed. Five stars for this…

Susan S.

Excellent experience all around. Communication from the company was timely and complete. My service technician Chad Wilson was very knowledgeable, efficient and helpful. I had a lot of questions, having just moved into a house with systems that were unfamiliar to me (geothermal, radiant heat). Chad answered all my questions and spent extra time helping me…

Mary C.

My family has been using this company for years. They've always provided us with honest feedback on pricing for repairs and maintenance. This means a lot to a family on a tight budget. We never feel like we are charged for unnecessary items. All charges are explained and examined in great detail before being followed through.…
