Landmark Home Warranty is a publicly held company committed to offering the highest level of service for all of your home warranty needs.

"Landmark Uses Disreputable Contractors ? AZA Repair & Brenovations HVAC Are the Worst Landmark sent AZA Repair for my refrigerator, and they left it worse than before?still not working, scorch marks from a blowtorch, copper lines sticking out, tools and oil left behind, and no receipt. Then Landmark sent Brenovations HVAC for an AC motor replacement, and that turned into exposed wires, bolts hitting fan blades, missing parts, and complete disregard for safety near my kids? play area. Both companies were unprofessional, negligent, and refused accountability. Landmark?s use of these contractors makes me seriously question the value of having a home warranty at all."

"This is THE worst company to ever use! They lie, rip you off and never call or communicate! This has been an ongoing problem from the initial install when the compressor blew up. They had to come back the next day with a new compressor to finish installation!! We’ve had problems ever since and this has been going on for 11 years. (We have a 12 year parts and labor warranty with a $49 deductible and we’ve paid this deductible so many times). Our compressor has gone out again, this is the forth time in 11 years!!!!! Tech brought out a portable air conditioner on Wednesday only to have it leak water on our living floor, rug and pad! He came back to pick it up and said the water plug was missing! Gee whose fault is that???? Was told we’d get a different one next morning on Thursday! Heard nothing on Thursday and nothing so far today, Friday! I’m sure we won’t hear a word! We’ve had parts put in backwards, txv’s (thermal expansion valve) replaced so many times, I lost count! Never ever use this terrible, inexperienced, sad excuse for a company!!"

Water Heaters questions, answered by experts

Choosing between an electric water heater vs. a gas water heater comes down to personal preference. Overall, electric heaters are more energy efficient than their gas competitors. They’re also quieter to operate, take up less room, and don’t come with a risk of gas leaks. 

The downside is that electric water heaters cost more to operate than gas. They might also struggle to heat water fast enough for households that use large amounts of hot water. Lastly, a power outage could cause your electric water heater to stop working, whereas gas water heaters may still function.

Replacing facilitates energy savings, decreases repair frequency, and aligns with modern safety regulations, maximizing safety.

Not all homes are required by code to have water heater expansion tanks, though some cities, like Los Angeles, do. Sometimes, municipalities will require a code that asks homeowners to install an expansion tank if their water heater is on a closed system. A closed system setup without an expansion tank can place unnecessary stress on appliances and shorten their lifespan.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.
