"This was a disaster that left me so angry I was literally Shaking! This company was sent by HSA Home Warranty another disaster look them up before you sign up. Anyway Simco was supposed to inspect the hot water heater for a leak to be replaced under the home warranty. The guy right off made a backhanded threat that he wouldn't condemn us and then became accusatory about the insulation on the water pipes saying what are you hiding here...the insulation was on the hot water side and was there when we bought the home this past November then he started nosing around and making other ******** comments. I worked in the trades myself and got very alarmed as he constantly was looking at gas pipes etc. This home had an engineer performed and certified inspection last November. I cant imagine what would have happened with an elderly and or female client. When I started questioning him he became very defensive and when I left to get my phone to record him in action he decided to leave!! Thank god for that!!! This is the worst experience of my 60 years."

Heating and Air Conditioning questions, answered by experts

You should have your AC coils cleaned once per year. To keep your AC unit in tip-top shape, consider cleaning your coils twice yearly—before and after air conditioning season. That way, the pro will remove any dust, dirt, and debris that has built up over the winter and catch new grime that accumulated during the summer. Additionally, if you’re handy, you can tackle any in-between cleanings yourself with a special fin comb.

Assessing location for airflow, convenience, and minimal noise impact.

There are a few factors to consider if you’re deciding between repairing and replacing your air conditioner. It’s probably worth fixing the AC unit if it’s less than 10 years old, you’re dealing with a one-off issue, and your warranty or maintenance plan will cover the repairs. On the other hand, if your air conditioner is dated, inefficient, out of warranty, and experiencing multiple problems, consider replacing it.

In many cases, replacing the entire AC system is a better investment than replacing a condenser or evaporator coil, as the labor and part prices can add up to a significant portion of the cost for a new system. Consult a licensed HVAC technician for an accurate diagnosis and recommendation.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.
