Our AC froze up about a week ago, and unfortunately it turned out to be a pretty serious refrigerant leak in the coil. Since the system is still covered under Lennox’s 5-year warranty, I started looking for a local Lennox-certified company and found Shamrock Heating & Air Conditioning.
They had someone out the very next day, quickly diagnosed the leaking coil, and then handled the entire warranty process with Lennox for us. They even arranged to have the replacement part shipped overnight, which we really appreciated after several very hot days without AC.
Jay was our technician for both visits and he was fantastic. He was knowledgeable, professional, friendly, and did an excellent job replacing the coil and getting everything back up and running.
After six days without air conditioning, having a cool house again feels pretty amazing!
We had a great experience with Shamrock from start to finish. We’ll definitely recommend them to our neighbors and won’t hesitate to call them again for any future HVAC needs.

Came out to my grandmother’s apartment destroyed her plants put the wrong coolant, then had to come back and drain it and put in the correct coolant, and I guess they were mad and stomped out her plant and killed it don’t use them if you care about your yard or good service

Took 2 days for a reply. Finally get someone to come out. Wires my a/c incorrectly, fan going the wrong way and hits me for a $2700 repair bill. Had another company come out, fix what this place did for a 1/5 of the price. Not totally sure they did this on purpose for a money grab or not but I’d stay away.

The first time I used them to replace LP gas lines for natural gas & install new HVAC, hot water heater and gas line to fireplace. They handled all state and manufacturer rebates. Then again when I moved I again replaced all units. They are very professional, efficient, have taken excellent care throughout many years. Highly recommend!!
Frequently Asked Questions About Shamrock Heating and Air Conditioning Inc
How often do I need to change my air filter?
As a general guideline, we recommend changing your air filter monthly. However, the frequency may vary depending on your location and the presence of contaminants such as dirt or pet dander. It's advisable to inspect your filter regularly and replace it when it appears dirty.
If I replace my outdoor unit, do I also need to replace my indoor unit?
In most instances, replacing both units simultaneously is advisable. Air conditioner and heat pump outdoor units are designed to work with matching indoor units. Using mismatched units can reduce efficiency and performance. Additionally, if both units were installed at the same time, the indoor unit is likely nearing the end of its lifespan as well. Replacing both units ensures a complete system warranty, potentially saving you from bearing the full cost of repairs during the warranty period.
Should I cover my unit in the fall and winter?
Covering your unit can help prevent debris accumulation, but it's important to note that operating the unit with the cover on can cause issues. If you plan to be away for an extended period and won't be using the unit, you may cover it. However, always remember to disconnect the power source before doing so.
How often should I have my unit serviced?
To ensure proper operation, we recommend having your heating and cooling units inspected and serviced annually by a professional HVAC technician. During these service visits, technicians will inspect your system, lubricate components, and address any malfunctioning parts through repair or replacement.
How do I find out if my unit is under warranty?
To determine if your unit is under warranty, locate the manufacture date on the label of your equipment's outer surface. If the unit is less than five years old, it's likely still covered by a warranty. For more specific details about your warranty coverage, we suggest contacting the manufacturer directly.
What can I do to lower my energy bills?
There are several steps you can take to reduce your energy bills: install a programmable thermostat to optimize heating and cooling when you're away; switch to energy-efficient lighting such as CFLs or LEDs; use ceiling fans instead of air conditioning when possible; unplug unused appliances to prevent standby power consumption; and ensure proper sealing of windows and doors to minimize air leaks and reduce strain on your HVAC system.
What's a good rule of thumb for changing the thermostat?
When adjusting your thermostat, consider the following: utilize programmable thermostats to set temperatures based on your daily schedule; adjust settings according to your comfort preferences and lifestyle; take into account outdoor temperature and humidity levels; and ensure your home is well-insulated to maintain consistent temperatures and improve energy efficiency.
