Is Your System Asking for Help?

Most breakdowns give a warning first. If you notice any of these, call before a small fix turns into a big one.

Air conditioner warning signs

Furnace warning signs

Before you call: four quick checks

These solve a surprising number of no-cool and no-heat problems. If none of them helps, call us and tell us what you already tried.

Check the thermostat

Set to Cool or Heat, a few degrees past room temperature, with fresh batteries.

Check the breaker

Look for a tripped breaker for the furnace or outdoor unit in your panel.

Check the filter

A clogged filter can freeze the AC coil or make a furnace shut itself off.

Check the drain line

A full condensate pan can trip a safety switch that turns the AC off.

 Trustindex verifies that the original source of the review is Google. I’m so grateful for Gelid-Tech coming out so quickly on such short notice! It’s Texas and over 100 degrees and he treated it as if he was the one stuck in a 94 degree house. He communicated throughout the day to reassure me they were coming even though it was late and went above and beyond to ensure I did not have to go another night without AC. I cannot thank him enough for his genuine concern and professionalism. He even took time to explain what happened and educate me on things to look out for or keep an eye on. Highly recommend calling them if you’re having HVAC issues!

 Trustindex verifies that the original source of the review is Google. I highly recommend Eli! My air conditioning went out yesterday evening, and the temperature inside my home climbed to over 90 degrees. He showed up exactly when he said he would, quickly diagnosed the problem, and did exactly what he promised. It’s refreshing to find someone who is reliable, professional, honest, and true to their word. Thanks to his prompt service, my home is cool and comfortable again. If you’re looking for dependable HVAC service, you won’t be disappointed!

 Trustindex verifies that the original source of the review is Google. I needed HVAC service desperately as the summer heat was arriving, and I didn't want to be taken advantage of. I had an idea of what was wrong, and I knew what I wanted to get done. Gelid-Tech came out, listened to me, checked the problem unit, and gave me repair options. One of the options was perfect for me. I was even able to finance the repair. Gelid-Tech came back on the scheduled repair date, completed the repair professionally, and left me with a unit that is cooling exquisitely. Prayer answered, and I am smiling instead of feeling unhappy and overcharged. If you have an AC issue, "Give Gelid-Tech a call".

 Trustindex verifies that the original source of the review is Google. I had a great experience with this company. The technician was very professional, respectful, and took the time to explain everything he was doing. He worked hard to diagnose and repair the issue, and I really appreciated his dedication and attention to detail. Even though it was a complicated repair, he stayed until the job was done right. I highly recommend this company and especially the technician who helped us Eli Dorilas. Thank you for getting our AC working again!

Repair or Replace Your HVAC System?

This is the question we hear most. Here is the rule of thumb we use when we look at an older air conditioner or furnace.

Usually worth repairing

See AC repair →

Time to consider replacing

See AC installation →

Not sure which side your system is on? A technician can check it and give you both options. Replacing? See our HVAC financing, or call (682) 392-2998.

HVAC Financing for a New AC or Furnace

A failed air conditioner or furnace rarely waits for a convenient time. Financing lets Mansfield homeowners replace an old system now and pay for it over time. If your system is still worth fixing, we will tell you, and point you to AC repair or furnace repair instead.

What you can finance

HVAC Service in Mansfield, Texas

Mansfield summers keep air conditioners running from May through September, and that is when most AC repair calls come in. If your unit is 12 to 15 years old, it may be time to look at AC replacement instead of another repair.

Winter is shorter but harder on old furnaces. During cold snaps we handle furnace repair and heating service calls, and our emergency HVAC service covers breakdowns that can’t wait. The easiest way to avoid both is a maintenance visit each spring and fall.

FAQ

Common HVAC Questions

Short answers to what homeowners ask us most. For anything else, call (682) 392-2998.

What HVAC services does Gelid Tech provide?

AC repair and installation, furnace repair and installation, heating service, seasonal HVAC maintenance and emergency service for homes in Mansfield, TX.

How often should I schedule HVAC maintenance?

Twice a year: the AC in spring before the heat arrives, and the furnace in fall before the first cold night.

When should I repair or replace my air conditioner?

If your AC is 12 to 15 years old, needs a repair every season or your bills keep climbing, replacement usually costs less over time. Our technician will tell you which side your system is on.

Does Gelid Tech provide emergency HVAC services?

Yes. If your heat or air conditioning stops working and it can't wait, call (682) 392-2998.

What areas does Gelid Tech serve?

We are based in Mansfield, TX and serve homeowners in Mansfield and nearby communities. Call (682) 392-2998 to confirm service at your address.

What are your business hours?

Our office is open Monday to Friday from 8 am to 5 pm and Saturday from 9 am to 3 pm. For urgent heating or cooling failures, ask about emergency HVAC service.

Why is my AC running but not cooling the house?

Common causes are a dirty air filter, a frozen evaporator coil, low refrigerant or a failing capacitor. Replace the filter first; if the air is still warm, turn the system off and schedule an AC repair so the compressor is not damaged.

How often should I change my air filter?

Check it every month and replace it every 1 to 3 months. In a Texas summer, when the AC runs all day, monthly is safer, especially with pets or allergies.

My AC uses R-22 refrigerant. Should I replace it?

R-22 has not been produced in the US since 2020, so recharging an older system gets expensive. If an R-22 system needs a major repair, replacement is usually the better value.

Do you offer financing for a new AC or furnace?

Yes. Financing is available for new air conditioners, furnaces and heat pumps, so you can spread the cost over time. Ask about options when you request a quote, or call (682) 392-2998.
