Hello. We want you to know we are taking extreme precautions with the current situation, so neither, you, your household/business or our techs are affected. We pre-screen all technicians every morning, checking for any signs or symptoms of the virus. All of our technicians wear protective gear, such as gloves and mask. They wash their hands prior to entry into your home and will practice social distancing while with you. It’s all part of an 8 step process we now go through to protect you and our technicians. As the weather is uncertain in the weeks to come, you and your family will be spending more time at home. You will definitely want to get your system ready, so no issues arise. Most of our work will be done in your attic, on your roof or outside. We will spend very little time in your home. Here at Coolmark Heating & Air, we are a locally owned and operated company that values honesty, integrity and treats your home as if it were our own. We offer a variety of quality home improvement services. You will find us to be competitively priced with close attention to the details of each and every project that we are involved with. We look forward to building lasting relationships and guarantee your satisfaction. We are on call 24/7 so please don't hesitate to reach out to us. Lastly, stay healthy and safe, we will overcome these trying times.
"We have had the best experience with the team at CoolMark and the owner himself, Mark Garza. They have gone over and above to help us out when our AC unit died, and even after the installation to ensure everything is working correctly. I felt bad bugging them when our new unit wasn't working right but they kept coming out until they discovered the problem, even coming out twice in the same day! Their services and the product they install were very competitive price wise and they worked with us to get the best financing options. I would highly recommend Coolmark Heating and Air to anyone needing service on their current unit or installing a new unit all together. You won't be disappointed!"

FAQs for heating and air conditioning service projects in Castle Hills, TX
Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.
While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.
The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.
Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
