 Trustindex verifies that the original source of the review is Google. The tech who came out to clear drip line from ac unit was great and very efficient. Would use their service again if needed.  3 text messages for this survey in a week seems a little heavy. Doing this to stop the text messages.

 Trustindex verifies that the original source of the review is Google. What a great company this is. I called at 3:00 on a Friday afternoon and they had a tech in my area who was there at 6. He quickly diagnosed the problem and got us up and running again. Very friendly and professional all around. I highly recommend and will definitely use them in the future.

Keep Your Heat Pump Running All Year

A heat pump runs in every season, which means twice the wear of a single-season system. The Lighthouse Annual Maintenance Plan keeps yours running efficiently year-round, catches small issues before they leave you without comfort, and protects your investment — season after season.

Still Have Questions? Let Us Help

Why is my heat pump not heating in winter?

Several issues can cause this — a failed reversing valve, low refrigerant, a faulty defrost control, or a stuck auxiliary heat setting. Because a heat pump both heats and cools, diagnosing the exact cause takes an experienced technician. We test the full system and pinpoint the real problem.

Why is my heat pump's outdoor unit covered in ice?

Some frost is normal in winter, and your heat pump periodically runs a defrost cycle to clear it. But if the unit is fully iced over or stays that way, it usually signals a defrost control, sensor, or airflow problem that needs professional attention before it damages the system.

Why is my heat pump running constantly?

Heat pumps run longer than furnaces by design, especially in very cold weather — that's normal and efficient. But constant running paired with weak heating or high bills can indicate low refrigerant, a dirty coil, or a failing component. We can determine whether it's normal operation or a real issue.

Should I repair or replace my heat pump?

It depends on the age of your system and the cost of the repair. Heat pumps typically last 10–15 years. If yours is newer, repair is usually the smart choice. For older systems with major repairs, we'll give you an honest comparison so you can decide what makes financial sense.
