Seasonal maintenances are a main factor in how your HVAC system works. You'll notice clean and proper air flow and added longevity to your system. We offer a Maintenance Plan that covers your twice-a-year recommended maintenances. Call or email today to ask about our Maintenance Plan.

For Carrier Products, please register online to receive a 10-year manufacturer part warranty. For Trane Products, there is no need to register — Trane now offers a 10-year manufacturer part warranty automatically.

Here are some things to check before calling:

• Have you replaced your air filters in the last 30 days? Dirty filters can cause blockage and system failure.
• Have you checked your breakers and/or disconnect switch? After a power outage, they may need to be reset.
• Is the power switch in your attic in the 'on' position? It looks like a light switch and is easy to miss.
• Did you recently replace your thermostat? Improper installation can pop a fuse — contact us for help.
• Do you notice oil residue at your exterior unit? This is a sign of a leak — contact HTM as soon as possible.

Replace your return air filters every 1-2 months. If you have media filters (located in your attic), we recommend replacing them every 4-6 months. Regular filter replacement ensures proper and clean air flow throughout your home.

Tips for keeping your home consistently cool:

• Schedule a maintenance with HTM or ask about our Maintenance Plan. Yearly maintenances are a must in Texas heat.
• Replace your filters regularly — dirty filters block air flow.
• Keep your system ON. Shutting it off to save money actually causes damage to your system.
• Set your thermostat to no more than 75 degrees on hot Houston days.
• Use window coverings to keep unwanted heat out.

If you notice water dripping from your exterior pipe, your primary drain line needs cleaning. We recommend getting your drain lines unclogged and cleaned twice a year. You can request this as a standalone service or add it to your yearly maintenance.
